Nyeem txog cov lus programming, koj yuav zaum hla cov lus parsing thiab scripting. Lub tswv yim ntawm kev faib tawm yog qhov yuav tsum muaj nyob hauv tsab ntawv, tab sis cov ntawv sau tsis tas ib txwm cuam tshuam nrog kev faib khoom.

Dab tsi yog parsing thiab tsab ntawv

Dab tsi yog hu ua tsab ntawv

Ib tsab ntawv yog ib qhov kev pabcuam me sau ua hom lus programming. Hauv Is Taws Nem, nws yog kev coj los hu rau cov kev zov me nyuam hauv PHP, Python rau kev ua ntau yam, nrog rau kev tswj hwm cov ntsiab lus, piv txwv li Wordpress lossis DLE.

Koj tuaj yeem sim sau koj cov ntawv yog tias koj txaus siab rau nws. Koj tsuas yog yuav tsum txiav txim siab txog hom lus uas koj yuav kawm. Lawv txhua tus muaj cov ntaub ntawv ntawm cov nom lub vev xaib hauv Is Taws Nem rau kev ua haujlwm syntax thiab cov qauv, nrog rau yam ntxwv. Cov txheej txheem programming yog zoo ib yam nyob txhua qhov chaw. Vim li ntawd, cov programmer uas paub zoo hauv ib hom lus thiaj yooj yim kawm lwm yam lus tau.

Lub koom haum pabcuam kuj tseem tuaj yeem ua qhov kev sau ntawv, uas pab lub ntsiab kom ua tiav lub hom phiaj kawg. Ntau zaus cov programmer yuav tsum sau ntau dua ib qhov chaws ua ntej yuav daws nrog lub luag haujlwm ntawm chaw ua haujlwm lossis ib tus neeg siv khoom.

Cov lus sau ua muaj ntau tshaj plaws PHP thiab JavaScript. Nws tsuas yog tsis yooj yim sua kom xav txog lub vev xaib tsis muaj lawv.

Ntsuas yog dab tsi?

Parsing yog lub tswv yim kev nqaim dua hauv cov cajmeem. Lub ntsiab lus ntawm kev sau cov cai los ua cov txheej txheem no tsuas yog khaws ib qho ntaub ntawv los ntawm lwm qhov chaw, ua nws thiab xa nws mus rau cov zis lossis xa mus rau lwm tsab ntawv ua cov ntsiab lus nkag rau kev ua haujlwm ntxiv.

Kev khiav dej num thiab cov tsev qiv ntawv txuas txuas ntxiv rau kev faib tawm yog nyob rau hauv txhua hom lus programming. Cov ntawv sau uas ua cov haujlwm no hu ua parsers. Raws li txoj cai, lawv tau raug sau kom tau txais qee cov ntaub ntawv los ntawm qee qhov tshwj xeeb, hloov kho cov ntaub ntawv tshiab tsis tu ncua. Txawm li cas los xij, muaj cov kev pabcuam puv ntoob rau lub Windows, ua haujlwm nrog uas tso cai rau koj los tsim ib tus qauv rau qee tus xaib.

Cov hom phiaj ntawm kev faib tawm tuaj yeem txuas rau cov nplooj ntawv sib txawv, chaw, duab, yeeb yaj duab, ntau cov ntawv nyeem los ntawm tej qhov chaw los ntawm coob tus ntawm nplooj ntawv. Ntawd yog, los ntawm kev xaiv lub khw online koj nyiam, koj tuaj yeem sau txhua yam khoom muag los ntawm nws thiab txhais lawv mus rau hauv hom ntawv xav tau rau upload rau lwm lub xaib.

Parsing tsis yooj yim sua yam tsis muaj kev paub txog kev hais tawm tsis tu ncua, uas nws txoj haujlwm yog tshawb rau cov khoom los ntawm qee tus qauv. Piv txwv, lub hom phiaj ntawm kev ua niam txiv yog nyob ntawm tus lej ntawm cov lej sib txawv, tab sis lawv ib txwm ib txwm naj npawb. Tom qab sau qhov tsim nyog ib txwm hais tawm, tsis muaj teeb meem dab tsi cov kab ntawv ntawm tus lej ntawm tib ntev, nws yuav pom tas li.
