Tsim ib lub rooj nyob rau hauv lub MySQL Tsim Rooj ntaub ntawv

Database, raws li variants ntawm lub concentration ntawm cov ntaub ntawv no tseem ceeb heev, thiab yog tsis muaj lawv yuav tsis ua txawm tias ib tug me me project. Yuav ua li cas zoo xav tawm qauv, zoo tsim ntxhuav, Mekas kev sib txuas lus - nyob rau cov qauv nqi / sau ntaub ntawv, cov ntaub ntawv muaj kev cia siab, tau lees tias cov impossibility ntawm cov lo mob, txaus rollback, lub tiav ntawm txhua lw - thiab txoj kev vam meej ntawm tag nrho cov.

Lub database yog feem ntau - conceptual lub tswv yim, kev nthuav qhia ntawm cov ntaub ntawv, thiab cov logic ntawm nws siv nyob rau hauv ib tug kev ua hauj lwm.

Tej yam yooj yim zoo siv piv =

Paub lub tswv yim ntawm Workers ntaub ntawv kom meej meej tsis yog tus zoo tshaj plaws, tab sis lawv confidently tuav tau lawv txoj haujlwm rau cov xyoo lawm. Raws li factories rau zus tau tej cov zaub mov thiab qhov tseem ceeb cov khoom mus rau cov neeg, lawv yog twv yuav raug hu xav tau.

Revolutionary tswv yim nyob rau hauv cov ntaub ntawv ua tau ntau lub sij hawm tshaj tawm hais tias lawv txoj cai mus rau lub neej, tab sis rau hnub no ua tsis tau tejyam rau muab tseem ceeb pov thawj ntawm lub hav zoov ntawm xws li ib tug txoj cai. Raws li ib txwm, simplicity - tus yuam sij rau kev kawm tau zoo. Txawm li cas los, cov ntsiab lus ntawm kev sib raug zoo thiab sib txuas ntawm cov ntaub ntawv khoom - cov ntsiab lus, thiab tshuab nyob rau hauv ntaub ntawv qhov chaw - tseem tag nrho cov dawb me ntsis thiab nthuav surprises.

Thov yooj yim qauv MySQL tsim rooj ua mus rau tsim ntawm tej yam yooj yim thiab yooj yim rau siv dozens ntawm cov ntxhuav, formalizing uas teeb meem. Pib siv "nqaij" yog yooj yim heev, tab sis tom qab thawj zaug kaum rooj ntawm paub kev sib raug zoo muab sawv mus rau ib tug cwj pwm sib txawv rau cov lus qhia, kev nthuav qhia, cia thiab siv.

Ib Ntus, tswj tau thiab qhov

Salient taw tes: "yuav tsum muaj lub tsev" database tswv yim tsis muaj kev koom tes los ntawm MySQL, uas tuaj rau lub neej nrog Internet programming thiab tau ua ib qho tseem ceeb ib feem ntawm nws. Dynamic, niaj hnub siv tshuab tau tso cai rau database los ua ib tug ceev ceev, txhim khu kev qha thiab zoo, yooj yim mus kawm thiab siv tau.

Nyob rau hauv tas li ntawd mus rau lub ntsiab ntxhuav tsim ib ntus rooj MySQL tsim tso cai rau lub programmer los tsim ib ntus ntaub ntawv lug nyob ua ib ke thaum lub sij hawm tam sim no kev sib kho, mus xyuas ntawm ib tug neeg, tshwm sim los ntawm ib tug kev tshwm sim.

Yog hais tias ua ntej lub rooj thiab kev sib raug zoo nruab nrab ntawm lawv raug kho raws li ib yam dab tsi indisputable, tab sis tam sim no tsis muaj lawm txais txawm haib database rau xa mus rau qhov siv khoom. Qhov no yog cia li ib kauj ruam mus rau kev to taub ntawm cov ntaub ntawv uas yuav tsum tau los mus daws cov teeb meem.

By muab ib lub cuab tam los tsim ib ntus rooj, tsim ib ntus rooj, MySQL tso cai rau koj mus phua lub database rau qhov zoo li qub thiab dynamic Cheebtsam. Specifying lub hom teb nyob rau hauv lub rooj, lub programmer tau txais tswj lub correctness ntawm nws tsim. Siv MySQL tsim rooj check tsim, cov designer yuav hais kom meej lub tej yam kev mob rau sau lub teb. Thaum qhov kev xaiv no - es ib lub sij hawm los pab txhawb lub tsiv teb tsaws ntawm designs ntawm lwm SQL dialects.

Cov ntaub ntawv chaw: cov ntsiab lus uas thiab tshuab

Txhua project, seb nws yog tag nrho cov qhov chaw, ib sab los yog ib tug yooj yim algorithm, yog nyob rau hauv ib tug tej yam qhov chaw ib tug tej yam lus qhia qhov chaw. "Chaw nyob" rau ntawm qhov chaw - ib tug cov hauj lwm, cov tej yam kev mob ntawm cov hav zoov ntawm cov algorithm: cov ntaub ntawv cov qauv rau lub inlet thiab qhov hluav taws xob, cov ntaub ntawv hloov siab los ntseeg.

Txawm li cas los, tsis tas yuav ua raws li cov kev cai ntawm MySQL, tsim rooj yuav tsis tsim uas nyob rau hauv raws li nws syntax.

Nyob rau hauv qhov kev piv txwv, teb code_back, owner_code session_code txhais lub lag luam thiab feem xa rov qab, thiab tus neeg kev sib kho. Tsis tsuas yog rau kev siv uas tsis yog-tus qauv version ntawm MySQL tsim rooj, qhov tseem ceeb no tsis dag nyob rau hauv nws daim teb ntawm tsis txawj txaus, thiab pleev xim rau nyob rau hauv lub ntsiab lus: rov qab los code nyob rau hauv cov ntaub ntawv ntawm tsis yog-kawm tiav ntawm cov kev sib pauv, lub active neeg code thiab kev sib kho code, uas tej zaum yuav tsum tau ob peb rau tus neeg, tab sis yog nyob ntawm nws, qhov chaw uas tus code yuav mus rov qab los xyuas dua.

Muaj kuj yog siv uas tsis yog-tus qauv teb h_code, a_contents thiab a_surprise. Ntawm no tsim rooj MySQL piv txwv ntawm yuav ua li cas ib tug teb yuav muaj cov ntaub ntawv, thiab semantics. Nyob rau hauv tej teeb meem no qhov twg koj muaj ib lub rooj ntawm cov neeg muas zaub, nws yog paub qab hau los ua ib tug cache ntawm lub active ib feem ntawm lub rooj. Qhov no tsis tas ua nws ib tug txaus thawj zaug qauv ntaub ntawv no. Piv txwv li, a_contents teb txheem: lub npe, lo lus zais; e-mail, thiab a_surprise teb - tam sim no lub xeev ntawm tus neeg siv.

Lub tswv yim a_contents thiab / los yog a_surprise

Tej embodiment tsis yuav tsum tau nkag mus rau lub ntsiab lus, uas yuav ua tau loj thiab cumbersome, thiab yuav txwv tsis pub cov me me, muaj tsuas yam ntaub ntawv. Ntawm no tsim rooj MySQL - ib qho piv txwv ntawm yuav ua li cas cov tswv yim tus neeg muas zaub lub npe thiab lo lus zais, los yog cov lo lus zais thiab e-mail nyob rau hauv yooj yim cov nqe lus: (a_contents zoo li '{$ cUserName}; {$ cUserPass}%') los yog (a_contents zoo li '% {$ cUserPass}; {$ cUserName} ').

Nyob rau hauv qhov kev piv txwv, siv nws tus kheej muaj nuj nqi check ntawm lub rooj: scTableExists ( 'rm_cache') raws li yog hais tias tus cov lus tsis yog, koj yuav tsum tau tsis tsuas mus rau tsim nws, tab sis kuj yuav sau, piv txwv li, thawj ob peb cov ntaub ntawv nrog rau cov ntaub ntawv kev pab cov thawj coj.

Standard variant tsim rooj yog hais tias tsis tshwm sim MySQL embodiment muaj raws qhov nyob rau ntawm lub rooj thiab nws tsim nyob rau hauv cov ntaub ntawv ntawm kev qhaj ntawv. Feem ntau, qhov no yog tsis txaus. Peb yuav tsum tsis txhob tsuas saib rau lub rooj, tab sis kuj sau nws nrog cov thawj cov ntaub ntawv.

yooj yim hom cell

Tseem ntawm MySQL siv hom lus, tshwj xeeb tshaj yog PHP, feem ntau yog minimizes tus nqi ntawm cov nrov cov ntaub ntawv: thawj thiab foremost, netipirovannostyu nws zog. Cov feem ntau siv hlua, raws li yuav tsum tau - tus naj npawb thiab hnub, tej zaum cov zajlus kom cov ntaub ntawv. Ntau lub sij hawm piav txog cov ntaub ntawv nyob rau hauv MySQL tsim rooj muaj tsawg. Txawm hais tias tom kawg yog txiav txim los ntawm qhov teeb meem yuav tsum tau solved. Koj muaj peev xwm siv rau tag nrho cov ntau yam ntawm cov ntaub ntawv ntawm tsim rooj MySQL, ib qho piv txwv - tej niaj hnub ntsiab lus tswj system website.

Yuav ua li cas thiab yuav ua li cas siv - sij tus tsim tawm. Thaum no tus taw tes nyob rau hauv lub sij hawm, raws li Wikipedia, cov ntim thiab ceev nta ntawm MySQL tau raws li qhov feem ntau capacious lub tswv yim ntawm cov qhua tuaj noj mov, noj mus rau hauv tus account qhov kev paub ntawm tus tsim tawm siv. Thaum uas siv los ntawm ib tug MySQL tsim rooj neej ntawd hais-lug cia rau tsim huv si (tas ntxhuav) nrog hlwb ntawm nce mus nce los ntev thiab tsim tau ib cov dynamic ntsiab lus nyob rau hauv tus txheej txheem.

Complex qauv ntaub ntawv no

Orientation rau tej yam yooj yim cov ntaub ntawv hom, thawj kab, tau coj mus rau nce paj nyob rau hauv lub tsim ntawm complex ntaub ntawv tej khoom uas thaum ua hauj lwm nrog cov database yog hloov dua siab tshiab rau cia nyob rau hauv lub ntsiab hlua, xov tooj (indexes - feem ntau), hnub, thiab "loj cov ntaub ntawv" - duab , suab, lwm yam capacious cov ntsiab lus. Ntawm no lub suab hais lus rau hauv lub tsim lub SQL Lub rooj lub MySQL zoo tsis muaj kev txwv. Rau tag nrho cov simplicity thiab cuag ntawm "nqaij" programmer muaj nyob rau hauv nws pov tseg rau hauv lub hwj huam tas nrho tiag SQL.

Lawv ua txuj coj yooj yim nyob rau hauv cov nqe lus ntawm hom ntawm tes database char los yog VARCHAR hloov dua siab tshiab nyob rau hauv lub algorithm rau kev nyeem ntawv nyob rau hauv ib tug tag nrho cov kwv - ib tug complex qauv ntaub ntawv no (zog, txoj kev, syntax thiab semantics), thiab thaum cov ntaubntawv povthawj siv dua twv mus rau hauv ib tug compact daim ntawv no, lub essence ntawm cov uas yog txiav txim los ntawm tus tsim tawm.

Lub tsev rooj

kem xwb, tsuas kab thiab tsuas yog ib lub caij nyob rau ntawm lawv cov kev tshuam, thiab tsuas yog ib hom - cell. Qhov no yog qhov yooj yim txoj cai qauv MySQL "tsim rooj". Tsis MySQL cov ntaub ntawv hom yog tsis thawj: tus xov tooj, cim txoj hlua, hnub ... Nws tsis ua raws li los ntawm cov syntax, tab sis nws puv tawm nyob rau hauv xyaum.

Programmer txhais tes muaj peev xwm zam nws ib yam ntawm cov kwv, vim yuav tsum ua hauj lwm. Los ntawm cov foundations ntawm lub database hais tias "txhua yam" - tsuas yog kab.

Txawm li cas los, tsis muaj teeb meem dab tsi, thiab yuav ua li cas siv tus tsim tawm prefers. Nws yog ib qho tseem ceeb uas nyob rau ntawm no taw tes rau hauv lub sij hawm (raws li Wikipedia) ntim thiab ceev MySQL tsis muaj peev xwm los siav tshaj plaws capacious lub tswv yim ntawm cov qhua tuaj noj mov, noj mus rau hauv tus account qhov kev paub ntawm tus tsim tawm siv.

"Tenacious" yog yooj yim heev cov lus, cov txheej txheem ntawm cov feem ntau yooj yim txoj kev. Yog hais tias tus tsim tawm txo nws hwj nyob rau hauv txhua txhua teb ntawm cov ntsiab lus, couching nws nyob rau hauv ib tug char los yog VARCHAR hom nyob rau hauv koj MySQL tsim rooj syntax, lub rooj yuav ua hauj lwm.

integer rooj

Peb kuj yuav tsum tham txog indexes nyob rau hauv MySQL. Tsim rooj tso cai rau koj kom sai li sai piav txog lawv thiab siv mus saib tau loj tagnrho ntawm cov ntaub ntawv. Qhov no mus kom ze yog heev nkag siab, paub thiab zoo tag nrho rau tej kev nthuav dav uas lub optimization nyob rau hauv lub CPU ceev, caching kuaj artful xam algorithms feem ntau xaiv cov ntaub ntawv editing php.ini, my.ini thiab httpd.conf.

Meanwhile, tsis muaj dab tsi tiv thaiv tus tsim tawm los tsim koj tus kheej saib "Cov ntaub ntawv" - "cov yuam sij rau cov ntaub ntawv" rau simplicity integer - tsis muaj kab nyob rau hauv lub rooj, tsuas yog tus xov tooj. Ib tug micro tsim rooj rau cov menyuam MySQL yuav muab tag nrho cov tsim nyog so ntawm lub qhov rooj: yooj yim nkag tau mus siv, yooj yim ua lag luam, tag nrho functionality ntawm qhov zoo tagnrho ceev.

Zauv, cov raws li ib tug tiag tiag cov ntaub ntawv cards nyob rau hauv loj thiab loj ntxhuav, yuav leeb xaiv thiab kev hloov kho ntawm cov ntaub ntawv tsis muaj teeb meem. Optionally tsim ib tug version ntawm qhov tseem ceeb ntawm kev nkag tau mus rau lub duration ntawm lub chaw ua hauj lwm, koj muaj peev xwm siv lub tsim ib ntus rooj qauv, MySQL tsim ib ntus rooj ua ntej yuav siv nws. Los yog, piv txwv li, rau txhua tus neeg siv - ib tug tseem ceeb lub rooj.

Nyob rau hauv qhov ntsiab lus teb, lub syntax yog tsis qhia kev siv ntawm tsim rooj yog hais tias tsis tshwm sim MySQL tso cai rau koj los mus tsim cov kev tsim nyog ntxhuav, txawm tias thaum ib tug npaj txhij txog qhaj ntawv, piv txwv li, yog ib tug tsis yog cov tswv yim / tso zis los yog computer crashes, thiab indexing disrupted.

Lub neej ntawm hosting - MySQL +

Keeb kwm, lub database yog ib tug muaj nuj nqis qauv ntaub ntawv no. Tsim M ySQL tsim rooj chiv ua raws li classical tswv yim ntawm cov ntaub ntawv thiab lawv qhov chaw nyob rau disk qhov chaw. Internet programming, thiab saum toj no tag nrho cov kev xaiv ntawm hosting thiab cov logic ntawm qhov nrov ntsiab lus tswj system, ua coj txawv txawv, thaum xub thawj siab ib muag, xaav: ib puag tej zaum yuav ib tug ua ke ntawm ob peb. Qhov kev sib cais yog nyob rau hauv lub rooj prefix lub npe.

Ib txhia hosting zov me nyuam tau yuam rau tus database lub npe ntawm lawv cov xav tau, xws li cov database lub npe pib nrog lub npe ntawm tus tswv hosting.

By thiab loj, nws tsis muaj nqi dab tsi yuav tau hu rau lub database thiab yuav ua li cas hu rau nws ib lub rooj. Txawm li cas los, qhov teeb meem no pib los sawv cev rau tsis yog ib tug MySQL syntax thiab yuav tsum txais ntxiv syntax, piv txwv li MySQL +.

Ib tug me me lus, qhov yooj yim dua nws yog txheej txheem, thiab cov uas tsis tshua nws cov ntaub ntawv, lub denser nws yog implanted nyob rau hauv hom lus programming uas los ntawm lub yam kev ua yog ua nrog cov ntaub ntawv.

Nyob rau hauv hauv paus ntsiab lus, tej hauj lwm yog ib qho yooj yim mus rau xim mus rau hauv elementary Cheebtsam, lub lus nug tsuas yog, ntau npaum li cas yuav raug nqi xws simplicity.

Yog hais tias koj xav tau ib tug huv si MySQL, nws tus kheej txais koj tus kheej neeg rau zaub mov, qhov twg yuav muaj tsis muaj kev txwv nyob rau hauv lub xov tooj ntawm databases los yog los ntawm cov kev cai ntawm tis npe rau lawv thiab lawv neeg ntxhuav.

Ib tug ntau yam ntawm versions ntawm Apache / MySQL / PHP

Nyob tos rau lub txais ib puag ncig - tsis yog li ntawd ntau npaum li cas cov teeb meem, raws li ib qho tseem ceeb mob rau ib tug niaj hnub defensive programming. Koj muaj peev xwm sau nyob rau hauv PHP 7.0.13, siv MySQL 5.7.16, tab sis tus neeg muas zaub yuav tsum hosting, uas tsuas version ntawm Perl thiab "nqaij" 4.1.1 los yog ib tug laus version ntawm PHP.

Nyob rau hauv kev (uas, incidentally, yog tsis yog ib tug fact) hosting muaj nyob rau ntawm Linux, FreeBSD, ubuntu thiab lwm yam variations yunikosopodobnyh systems. Lawv tag nrho cov ua hauj lwm zoo, tab sis txhua yam uas lawv muaj nws tus kheej cov yam ntxwv, lawv tus kheej versions ntawm cov rooj sib txoos AMP (Apache, MySQL, PHP). Tsis yeej ib txwm thiab tsis yog txhua pab neeg no yog mus ua hauj lwm nyob rau hauv lub tom ntej no version, tab sis yog nws ua hauj lwm nyob rau hauv lub yav dhau los yog ib tug.

Xws li ib tug yooj yim lub lag luam raws li ib tug database export tej version ntawm MySQL puas tsis muaj teeb meem, ob qho tib si los ntawm Ntshuam Ntshuam phpmyadmin, thiab los ntawm cov kab hais kom ua. Tiv tauj ntshuam hauj lwm yuav tsis muab qhov chaw. Ntau zaus tshaj tsis muaj hloov ib yam dab tsi nyob rau hauv koj lub PHP, MySQL neeg rau zaub mov los yog Apache. Yog hais tias cov kev hloov tsis tau kev pab, nws yog tsim nyog los saib rau lwm txoj kev.

Qhov yooj yooj yim fact, ib lub lag luam yuav tsum tau ua los ntawm resetting lub database, hom lus programming los yog cov neeg rau zaub mov. Qhov no yog tsis zoo tshaj plaws tshuaj, tiam sis feem ntau zoo.

Lub database creation / validation rooj

Syntax MySQL tsim rooj tsis tshua siv nyob rau hauv nws cov txheej txheem embodiment. Yog hais tias nws tsis yog nyob rau hauv lub ntsiab lus teb ntawm qhov nrov ntsiab lus tswj system: yuav muaj yeej ib txwm yog ib tug classic ntawm ib hom ntawv nyeem. Lub sij hawm ua hauj lwm yog ib qho yooj yim mus xav txog nws nyob rau hauv lub ntsiab lus teb ntawm kev xyaum: uas tau teb cov uas yuav tsum tau nyob rau hauv lub rooj, uas lawv yuav tsum muaj ib yam thiab loj. Tus so tseem yuav tau cais puab cov txheej txheem ntawm txoj kev loj hlob: lub cim txheej, tsi kev txiav txim, lub lag luam.

Optimum yog ib tug version ntawm tus algorithm, nyob rau hauv uas txawm cov tsis muaj ib tug database tsis cuam tshuam nrog rau cov chaw mus pib. Koj muaj peev xwm sau koj tus kheej muaj nuj nqi kos rau lub database thiab / los yog lub rooj thaum koj yuav tsum tau tsim tsis tsuas cov ntaub ntawv lug, tab sis kuj yuav sau nyob rau hauv lawv cov thawj cov ntaub ntawv.

Heev feem ntau siv ib tug series ntawm designs Tsim rooj yog hais tias tsis tshwm sim, MySQL tsis surprise lub site tswv los yog ib tug qhua uas mam li nco dheev hais tias: yog tsis muaj database los yog cov lus qauv yog lawm.

Nyob rau hauv niaj hnub programming kev cai ntawm "cia siab rau tab sis tseeb" yog tsis ua hauj lwm, los yog es yuav siv cov logic ntawm lub "kos thiab siv."

Tsim rooj: MySQL neeg siv rooj qauv

Sau npe ntawm tshiab qhua thiab cov kev nkag / tawm ntawm qhov chaw cov neeg muaj tsim heev heev lub sij hawm, tab sis cov kev txwv ntawm perfection nyob rau hauv no tseem ceeb heev ib feem ntawm kev kawm ntawv tsis tau.

Nyob rau hauv ntau txoj kev, tswv yim / tso zis thiab sau npe yog txhais los ntawm cov nqe lus ntawm reference ntawm lub site thiab / los yog siv cov ntsiab lus tswj system, tab sis ntau ntau - lub siab xav los tsim ib yam dab tsi ntau ruaj ntseg, tiv thaiv cov neeg siv nyiaj, tiv thaiv hacking site.

Feem ntau MySQL database yog ntau ruaj ntseg tshaj li ib lub website, tab sis nyob rau hauv cov ntaub ntawv ntawm tsis ua hauj lwm tsis tau kav zaub browser kev ua yuam kev cov lus uas cov configuration code ntawm ib qhov chaw, uas muaj cov npe thiab passwords rau lub database.

Zoo xyaum - muab cov ntaub ntawv nyob rau hauv qhov zoo li qub thiab dynamic Cheebtsam. Nyob rau cov piv txwv ntawm ib tug neeg cov lus, uas koj yuav muaj ib tug loj spreadsheet cov neeg siv thiab active cache_users. Tus thawj rooj muaj ib tug loj tus naj npawb ntawm cov neeg siv, qhov thib ob - tsuas yog cov neeg uas ua hauj lwm nyob rau hauv lub xeem hnub (piv txwv li). Txhua tshiab cov neeg siv uas yog tsis tuaj kawm ntawv nyob rau hauv lub rooj thib ob, tuaj muaj tom qab rau kev nkag / txais tos thiab khaws cia rau tej lub sij hawm.

Tab sis lub division rau hauv ob lub rooj no tsis tsuas yog muab cov ntaub ntawv coj tus nqi (ib tug me me lus no yog yeej ib txwm sai dua loj thiab loj loj), tab sis kuj nyob rau hauv lub fact tias nws fits tsuas cov ntaub ntawv uas yuav tsum tau ntau tshaj thaum kev khiav hauj lwm tej qhua tuaj noj mov ntawm ib tug qhov chaw. Rau piv txwv los yog cov ntaub ntawv hloov lawm siv lub ntsiab lus.

Nco, cov ntaub ntawv thiab databases

Nyob rau hauv lub teb ntawm cov ntaub ntawv technology cas muaj tsis tsim los sawv cev rau lub cim xeeb programming lus. Lus - lub zog, constants thiab lug, uas ib yam dab tsi thiab cas manipulated. Database - yog ib yam dab tsi khaws cia. Los ntawm nws koj muaj peev xwm xaiv ib yam dab tsi nyob rau hauv nws koj yuav sau ib yam dab tsi.

Ua ke lus thiab lub moj khaum rau lub hom phiaj ntawm kev ua hauj lwm uas muaj ntaub ntawv, tab sis cov logic ntawm lub kev sib raug zoo nyob rau hauv no triad yog tsis yog li ntawd zoo meej, txawm nyob rau hauv ib tug yooj yim Rev ntawm AMP: Apache, PHP, MySQL. Ntawm no txhua yam yog tseeb: lub neeg rau zaub mov, hom lus programming thiab cov database - tag nrho cov uas yuav tsum tau rau feem ntau ntawm kev pab raws qib.

SQL lus - tib yam programming lus, thiab nyob hauv lub database muaj nws tus kheej logic ua hauj lwm, tus kheej programming tswvyim. Ntawm no yog peb muaj lub siab xav mus database programming sab. PHP - ib tug zoo twj, tab sis hais tias nws yog ua phem rau ntau database sab, nws yog ib qhov nyuaj. Txawm li cas los, nws cov qauv thiab kev khiav dej num tsim thiab zoo tuaj.

Yog hais tias peb muab PHP thiab MySQL nyob rau hauv ib chav tsev xwb, koj yuav tau txais lub cuab tam, muaj ib tug nco. Option thaum lawv tseem muab lub tswv yim ntawm yam khoom-taw qhia kom paub programming: tus kwv piav nyob rau hauv cov lus thaum lub sij hawm ntawm lawv cov uselessness nyob rau hauv lub cim xeeb (nyob rau hauv lub database) nyob rau hauv ib tug compact lub xeev. Thaum nws yuav tsim nyog, nws yog txo mus rau hauv ib tug tag nrho cov kwv thiab ua hauj lwm nyob rau hauv raws li nws tsis txawj txaus.
