Kodi PHP programming ndi chiyani?

The PHP Programmiersprache has emerged as one of the most popular and widely used languages to build websites. Ndiwofulumira komanso yosavuta kuphunzira Object-Orientierte Programmiersprache yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana., kuchokera ku machitidwe a masitolo ndi machitidwe oyendetsera zinthu kupita ku hosting web. Ngati mukufuna kudziwa zambiri za PHP, werenganibe.

Chilankhulo chokhazikika cha mapulogalamu

PHP has evolved into an ObjectOrientated programming language, mawu omwe amatanthauza “kupanga zinthu.” Pamene PHP 4 anali ndi ObjectOrientation, kutulutsidwa kwaposachedwa kwa PHP, PHP 5, ndi ObjectOriented kwathunthu. Izi zikutanthauza kuti PHP siyikutsaliranso kumbuyo kwa zilankhulo zina zamapulogalamu ikafika pamapulogalamu omwe amatsata zinthu. Pali malingaliro olakwika, komabe, izo zikupitirirabe.

Zilankhulo zokhazikika pazifukwa zimagwiritsa ntchito makalasi kukonza deta m'njira yomveka. Kalasi iliyonse imayimira mtundu wina wa data. Maphunzirowa ali ndi njira ndi zikhumbo ndipo amagwiritsidwa ntchito ngati maziko a kugwirizana kwa chinthu. Maphunzirowa amagwiritsidwa ntchito kutengera mitundu ya data yovuta. Mosiyana ndi ma datatypes osavuta omwe amagwiritsidwa ntchito pamakhodi achikhalidwe a PHP, OOP imalola kuti deta ikhale yolongosoka.

Mapulogalamu otsata zolinga ndi njira yabwino yopangira ma code anu kukhala osavuta kusunga. Mutha kugwiritsanso ntchito ma code ndikugwiritsanso ntchito zida popanda kuda nkhawa kuti zikusemphana. Izi ndizothandiza makamaka mukamagwira ntchito zazikulu, zovuta ntchito. Kugwiritsira ntchito mapulogalamu a Object-Oriented kumapangitsa kukhala kosavuta kusunga ndi kugwiritsanso ntchito code.

Ubwino wa mapulogalamu okhazikika pazinthu zambiri. Zimakupatsani mwayi wothana ndi zovuta zovuta pobweretsa mulingo watsopano wachinsinsi ku code yanu. Izi zimachitika pogawa ma code m'magulu osiyanasiyana. Maphunzirowa ali ndi mitundu ya data ndi machitidwe omwe amatha kusinthidwa kapena kugwiritsidwanso ntchito pazifukwa zosiyanasiyana.

Mapulogalamu otsata zolinga ndi njira yabwino yopangira mawebusayiti osinthika. Ili ndi kusinthasintha kochulukirapo kuposa HTML, ndipo ndi yosavuta kuphunzira ndi kugwiritsa ntchito. Ndi njira yabwino yopangira pulogalamu yamabizinesi payekha. Kuwonjezera pa kupanga webusaiti yamphamvu, PHP imakupatsani mwayi wopanga mapulogalamu omwe ndi apadera kwa kampani yanu.

Mapulogalamu otsata zolinga mu PHP amakupatsani mwayi wolekanitsa makalasi anu kwa wina ndi mnzake. M'malo mokhala ndi kalasi imodzi yayikulu ndi angapo ang'onoang'ono, mukhoza kukhala ndi makalasi osiyana ndi njira kalasi iliyonse. Zotsatira zake, code yanu imasinthasintha, zambiri zosanjidwa, ndi zambiri zothandiza. Zimakupatsaninso mwayi wowongolera khodi yanu bwino.

Njira yabwino yopezera chinenero chodziwika bwino cha mapulogalamu anu ndikufunsana ndi netiweki yanu. Ngati muli ndi digiri kale m'munda wokhudzana ndi sayansi yamakompyuta, mutha kufunsa anzanu kuti amagwiritsa ntchito chilankhulo chanji. Atha kukupatsani malangizo kapena kukuuzani za zilankhulo zapadera zomwe mungaphunzire panokha. Mutha kusakanso maudindo pa Stellenanzeigen kuti muwone zilankhulo ndi kuphatikiza zomwe zikufunidwa.

Kuwonjezera pa PHP, mutha kugwiritsanso ntchito zilankhulo zina zamapulogalamu. Ruby ndi mmodzi wa iwo. Komabe, chinenerochi chili ndi zovuta zina. Mwachitsanzo, Ruby ndi wochedwa kwambiri. Ruby amagwiritsa ntchito mitundu ya data.

PHP is a highly flexible and powerful programming language that supports multiple databases and real-time monitoring. Mawonekedwe ake a datenbank-ochezeka amapangitsa kukhala chisankho chabwino pakukula kwa intaneti. PHP ndi gwero lotseguka, kutanthauza kuti aliyense akhoza kukopera ndi ntchito kwaulere. Palinso gulu lalikulu la PHP lomwe limagawana malangizo ndi chidziwitso.

PHP imagwiritsidwa ntchito kwambiri pamakampani opanga mawebusayiti. Kutchuka kwake ndikwambiri, ndipo nthawi zambiri amagwiritsidwa ntchito pama code kumbuyo kwa masamba ena akulu kwambiri pa intaneti. Kuphatikiza apo, PHP ndi yaulere ndipo imasinthidwa nthawi zonse. Ngakhale, pali zovuta zochepa, kuphatikizapo scalability yake yochepa ndi zosayembekezereka, PHP ndi chisankho chokhazikika.

PHP ili ndi mawu osavuta, kupangitsa kukhala kosavuta kwa opanga mapulogalamu kuti asinthe. Imaphatikizidwanso mkati mwa HTML, kutanthauza kuti code yalembedwa bwino kwambiri. PHP ndi chilankhulo champhamvu komanso chosinthika chomwe chimatha kuthetsa mavuto ovuta, kupititsa patsogolo mpikisano wamakampani. Motero, ndikofunikira kuti muphunzire ndikumvetsetsa chilankhulocho kuti mupange mapulogalamu ofunikira kwambiri pa intaneti ndi mapulogalamu.

Ndikofunikiranso kukhala otetezeka popanga mapulogalamu a pa intaneti. Kafukufuku waposachedwapa anapeza zimenezo 86% ya mapulogalamu a PHP anali ndi chiopsezo chotchedwa XSS. Awa si mapeto a dziko, monga gulu la PHP latenga njira zambiri kuti PHP ikhale yotetezeka. Komabe, PHP siyotetezedwa kwathunthu, ndipo pamafunika chisamaliro ndi chisamaliro chochulukirapo kuti tipewe ziwopsezo zachitetezo. Ngati mukukhudzidwa ndi chitetezo, Python ndiye chisankho chabwinoko. Ili ndi zinthu zambiri zotetezera ndipo imatha kugwira ntchito zovuta kwambiri.

Kuphunzira chinenero chatsopano cha mapulogalamu ndikovuta, koma ndizosavuta kuposa momwe mungaganizire. Ngati ndinu watsopano ku coding, ndi bwino kuyamba ndi chinenero chosavuta chimene mungaphunzire, kenako onjezerani kuchokera pamenepo. Ndibwinonso kuyamba ndi chilankhulo chomwe chimagwira ntchito ndi malaibulale ndi mafelemu. Kuphatikiza apo, ndikofunikira kuganizira mtundu wa projekiti yomwe mukufuna kukhazikitsa ndi chilankhulocho.

Ngati ndinu watsopano ku lingaliro la chitukuko cha intaneti, PHP ikhoza kukhala njira kwa inu. Ndiosavuta kuyamba ndi PHP. Chilankhulochi chili ndi ntchito zambiri ndipo chingathandize aliyense wopanga mapulogalamu. Mawu ake amamveka bwino komanso osavuta kuwerenga, zomwe zimapangitsa kuti zikhale zoyenera kwa oyamba kumene. Ndi chisankho chodziwika bwino kwa opanga mawebusayiti.

PHP imakhalanso yachangu kuposa zilankhulo zina zambiri zamapulogalamu. PHP 7.x yakonza kusanjikitsa ma code ndipo ikufika ku 2x mwachangu kuposa yomwe idakhazikitsidwa kale. Ndi zatsopano zake monga Zend Engine 3.0, PHP ndiyothamanga kwambiri kuposa kale. Komanso, chinenerocho n'chosavuta kusanthula zofunikira kusiyana ndi zilankhulo zina zamapulogalamu.

Zikafika pamapulogalamu, PHP ndi chisankho chodziwika bwino kwa opanga mawebusayiti. Ndiosavuta kuphunzira ndikugwiritsa ntchito, ndipo imasinthasintha kuposa Java. Zimakupatsaninso mwayi wogwira ntchito ndi ma code osagwirizana komanso aulere, zomwe ndi phindu lalikulu kwa opanga. Komanso, PHP ndi gwero lotseguka ndipo imayenda pa nsanja iliyonse.

Kukonzekera kwa Object-Oriented (UWO) ndi njira yopangira mapulogalamu omwe amagwiritsa ntchito zinthu ngati zomangira pulogalamu. Mwa njira iyi, zinthu zimatanthauzidwa ngati zinthu zomwe zilipo panthawiyi. Mabungwewa amathanso kukhala ndi katundu ndikulumikizana ndi zinthu zina. Zinthu zimasiyana ndi makalasi, zomwe ndi zidutswa za code zomwe ziyenera kuyesedwa ndikukhalabe chimodzimodzi. PHP imagwiritsa ntchito utsogoleri wamakalasi, zotchedwa Zinthu, kupanga ntchito ya pulogalamu.

Kukonzekera kwa Object-Orient mu PHP kumapangitsa kukhala kosavuta kugwiritsanso ntchito ndikusunga ma code. Lingaliro la Object-Orientation nthawi zambiri limakhala lothandiza pamagwiritsidwe ovuta. PHP 5 ali ndi ubwino angapo kuposa Mabaibulo oyambirira. Kwa chimodzi, imapereka kuwongolera kwabwinoko pamakhalidwe ndi katundu. Izi zimalola opanga kulemba zolemba zovuta kwambiri munthawi yochepa.

PHP imaperekanso njira zamatsenga, zomwe nthawi zambiri sizimayitanidwa ndi wogwiritsa ntchito koma zimatchedwa PHP zikakwaniritsidwa. Njirazi zimatchedwa ndi double-understroke, ngakhale kuli bwino kupewa kugwiritsa ntchito khalidweli potchula njira. Njira zithanso kugawidwa m'magulu.

Mu PHP, makalasi ali ndi katundu wamba komanso wamba. Katundu wamba ndiwo otetezeka kwambiri. Katundu wamba amafikiridwa ndi mamembala okha a kalasi. Katundu wamba, monga chomwe chimagwiritsidwa ntchito polenga chinthu, sizipezeka pagulu. Makalasi amathanso kugwiritsa ntchito pfeiloperator -> kupeza katundu wawo ndi njira zawo.

Mapologalamu a Object-Oriented amalola opanga kutengera dziko potengera zinthu. Zinthuzi zili ndi deta ndi njira ndipo zingagwiritsidwe ntchito pazinthu zosiyanasiyana. Makalasi amatanthauzidwa kukhala magulu ofanana zinthu. Pamene kalasi ikufotokozedwa, The Object imatha kugwira ntchito zingapo ndikugwiritsidwanso ntchito.

Mapulogalamu Otsata Zinthu amalola opanga kulemba mapulogalamu omwe amagwiritsa ntchito database. Zinthu zitha kupangidwanso ndikusungidwa mkati mwa mafayilo a PHP. Izi ndizotheka pogwiritsa ntchito arrays. Pogwiritsa ntchito masanjidwe, mukhoza kusunga zinthu zambiri nthawi imodzi. Mukhozanso kugwiritsa ntchito lamulo lokhazikika lotchedwa echo. Mutha kuyikanso timagawo zingapo zamakhodi mu HTML yomwe ilipo.

Monga dzina likunenera, Mapologalamu a Object-Oriented amagwiritsa ntchito mikhalidwe kuwongolera kayendedwe ka chidziwitso. Uku ndi kusiyana kwakukulu pakati pa mapulogalamu ofunikira komanso ogwira ntchito. Ngakhale kuti zilankhulo zonsezi zimagwiritsa ntchito zikhalidwe kuti zisamalire deta, kalembedwe kantchito kumafuna kukhazikika komanso kusinthasintha. Madivelopa a PHP amatha kulemba kachidindo komwe kamagwira ntchito bwino kwa gulu lawo pogwiritsa ntchito njira yotakata.

OOP amagwiritsanso ntchito lingaliro la kalasi, zomwe zikuimira chinthu chenicheni. Chinthu ndi chitsanzo cha kalasi. Mwachitsanzo, dzina la munthu, zaka, nambala yafoni, ndi mfundo zina zikhoza kusungidwa m’kalasi la munthu. Chinthu chingathenso kukhala ndi njira ndi mfundo zomwe zimakulolani kuti muzichitapo kanthu.
