Zomwe Muyenera Kudziwa Zokhudza PHP Programmierung

If you are thinking of developing a web project, you may want to learn more about PHP programmierung. Pali zabwino zingapo m'chinenerochi, kuphatikiza kutchuka kwake pakati pa mabungwe apa intaneti komanso kukhazikika kwake. PHP ndi chisankho chabwino kwa oyamba kumene, popeza zimalola opanga mawebusayiti kupanga masamba osinthika mosavuta komanso popanda kukangana kwakukulu. Nkhani yotsatirayi ifotokoza PHP, Symfony, ndi Mapologalamu olunjika pa chinthu.

Symfony

If you’re looking for a framework for developing web applications, Symfony ndi chisankho chodziwika bwino. Cholinga chachikulu cha chimango ichi ndi kufewetsa chitukuko, komanso imathetsa ntchito zobwerezabwereza. Ngakhale sizibwera ndi gulu la admin, Symfony ili ndi mndandanda wazinthu zomwe zingagwiritsidwenso ntchito, PHP library, ndi dongosolo lachikwatu lolimba. Izi zikutanthauza kuti code yanu idzakhala yomveka komanso yowerengeka, ndipo zidzathandizira ntchito yachitukuko.

Monga momwe zimakhalira ndi machitidwe ena, Symfony idapangidwa kuti izithandiza omanga kupanga mapulogalamu a pa intaneti powapangitsa kuti azigwira ntchito ndi owongolera-mawonekedwe (MVC) zomangamanga. Zomangamanga za MVC zimakuthandizani kuti mukhazikitse zosintha pakati, ndipo simudzasowa kusintha ma code akuluakulu. Ndondomekoyi imapangitsanso kukhala kosavuta kuyang'anira malo pochotsa zigawo zosafunikira ndikupangitsa kukonza kukhala kosavuta. Zomangamanga za Symfony-view-controller ndi njira zopangira zosavuta kupanga mapulogalamu onse a pa intaneti.

Ngakhale kukhala open source, Symfony imathandizidwa ndi malonda. Madivelopa ake ali ndi kudzipereka kwakukulu ku chimango ndikuchithandizira ndi misonkhano ndi maphunziro ovomerezeka. Zochulukirapo, gulu lachitukuko cha chimango likugwira ntchito kwambiri, ndipo imathandizidwanso ndi kampani yayikulu yolumikizana, SensioLabs. Zotsatira zake, pali misonkhano yambiri ya akatswiri, maphunziro, ndi certification kwa Symfony Madivelopa.

PHP

PHP ndi imodzi mwazilankhulo zodziwika bwino za seva. Yopangidwa ndi Rasmus Lerdorf, PHP imagwiritsidwa ntchito ndi oposa 240 miliyoni mawebusayiti ndi kupitilira 2 mamiliyoni a seva za intaneti. M'mbuyomu 20 zaka, PHP yasinthidwa kangapo kuti ikhalebe yatsopano komanso yothandiza. Lero, PHP imagwiritsidwa ntchito kupanga mitundu yosiyanasiyana yamasamba, monga zolemba za blog, mabwalo, ndi maakaunti a ogwiritsa ntchito. Mutha kuphunzira kulemba nambala ya PHP kuti mupange tsamba lanu.

Chilankhulo cholemberachi chingagwiritsidwe ntchito pamitundu yonse. Amagwiritsidwa ntchito kwambiri pakupanga intaneti ndipo amagwiritsidwa ntchito popanga mapulogalamu osavuta opangira ma data. PHP imagwirizana ndi MySQL, seva yaulere ya database. Zimakupatsaninso mwayi kutumiza deta yosungidwa pa seva yanu. Mutha kuphunzira kugwiritsa ntchito PHP lero pochita maphunziro a PHP. Pali zabwino zambiri zophunzirira PHP. Mfundo zotsatirazi zakonzedwa kukuthandizani kuti muyambe. Ganizirani ntchito mu PHP lero!

Phindu limodzi lalikulu la PHP ndikutha kukonza zomwe ogwiritsa ntchito amalemba. Ngakhale HTML siyitha kuyika zolowetsa zamtunduwu, PHP akhoza. Pogwiritsa ntchito luso limeneli, mutha kusintha masamba a HTML kukhala PHP, kenako zikwezeni ku seva ndikuzipempha popanda kuzisintha. Izi zimapangitsa PHP kukhala chida chachikulu cha E-Commerce. Akagwiritsidwa ntchito moyenera, PHP itha kugwiritsidwanso ntchito kupanga zinthu zopangidwa ndi ogwiritsa ntchito ngati mafayilo a PDF, Makanema a Flash, ndi mafayilo a HTML. Komanso, PHP imakulolani kuti musunge mafayilo anu opangidwa pogwiritsa ntchito cache ya mbali ya seva.

Object-oriented programming

One important concept in Object-oriented PHP programming is using the constructor of the parent class. Nthawi zina, sizingakhale zotheka kuitana womanga kalasi ya makolo popanga chinthu. Zikatero, mutha kuyimbira womanga gulu la makolo pogwiritsa ntchito opareshoni ya scope resolution “.:”. Njirayi imatha kuvomereza mfundo imodzi kapena zingapo. Womanga ndiye njira yayikulu ya chinthu. Imatchedwa womanga chifukwa imagwira ntchito ngati pulani yopangira zinthu zatsopano.

Gawo loyamba la mapulogalamu a PHP opangidwa ndi Object limaphatikizapo kupanga ma interfaces. Mawonekedwe ndi gulu lapadera lomwe limalola opanga kufotokozera ndikukhazikitsa mapulogalamu awo. Ndilofanana ndi kalasi kupatula kuti ilibe thupi. Mawonekedwe amatha kupangidwa pogwiritsa ntchito mawu osakira mu PHP. Imathandizira opanga kalasi kuti awonjezere njira zapagulu popanda kukhazikitsa. Motsutsana, mawonekedwe amatha kusiyanitsidwa ndi kalasi ndipo amatha kukhala ndi zochitika zingapo.

Mu mapulogalamu a PHP opangidwa ndi Object, kalasi imaphatikiza zomwe munthu wapatsidwa, banja, ndi mayina ena. Kuphatikiza apo, Mchitidwe wabwino wa OO ndikuwulula minda yachinsinsi kudzera munjira zapagulu zotchedwa accessors. Izi zimapatsa anthu njira yosavuta yopezera chidziwitso mu kalasi ya PHP. Mwa njira iyi, mukhoza kusunga dongosolo lomwelo popanda refactoring code yanu. Mapulogalamu a PHP okhazikika pa zinthu amathandizira njira yopangira mawebusayiti.

Prozedural programming

There are two approaches to computer programming: mchitidwe ndi zolunjika pa chinthu (UWO). Ngakhale code code ndi njira yabwino kwa oyamba kumene, si njira yabwino kwa akatswiri. Ndondomeko ya PHP ya Procedural imatsatira mfundo zofanana ndi za OOP, monga kugwiritsa ntchito zinthu ndi njira. Mu ndondomeko code, sitepe iliyonse imagwira ntchito inayake. Kugwiritsira ntchito ndondomeko kapena chunk code, kuyika kachitidwe kumatsata mfundo zamapulogalamu otsata zinthu.

PHP ndi chilankhulo chotsatira. Zotsatira zake, sichigwiritsa ntchito maziko aliwonse, zomwe zimapangitsa kukhala kosavuta kupanga mapulogalamu. Pomwe PHP imagwiritsa ntchito pulogalamu yamachitidwe, Maphunziro ake ambiri amalembedwa m'chinenero chotchedwa C. Kaya woyambitsa amatenga njira iti, ndondomeko idzawathandiza kupanga maziko olimba a ntchito zamtsogolo. Ndipo malinga ngati amvetsetsa zoyambira zachilankhulocho, adzatha kupanga mapulogalamu ogwira ntchito posakhalitsa.

Mfundo ina yofunika kwambiri pakupanga mapulogalamu ndi DRY, kapena “osadzibwereza”. Izi zikutanthauza kuti simuyenera kubwereza pokhapokha ngati pakufunika kutero. M'malo mwake, muyenera kuyika nambala wamba pamalo ogwiritsidwanso ntchito. Mu ndondomeko code, code yomweyi imatha kuwoneka nthawi zambiri m'malo osiyanasiyana. Zomwezo zimapitanso kuzinthu. Khodi yokhazikika pazinthu ndiyosavuta kuyisunga ndikusintha. Uwu ndi mchitidwe wabwino kwa aliyense wopanga PHP.

Frameworks

Whether you’re building an application for a client, kapena mukuyang'ana kuti muchepetse chitukuko, Mapulogalamu a PHP angapangitse kuti ntchitoyi ikhale yosavuta. Zomangamanga za PHP zimapereka ma module omangidwa kale ndi maziko omwe amatenga zolemba zambiri zotopetsa pa mbale yanu.. Posankha chimodzi, ganizirani zofunikira za polojekiti yanu. Zolinga za PHP zili ndi magawo osiyanasiyana othandizira aboma, thandizo la anthu ammudzi, ndi zolemba. Pomaliza, muyenera kusankha chimango malinga ndi zosowa zanu.

Zambiri zamapulogalamu a PHP zilipo, koma pali ochepa otchuka omwe mungasankhe. Mwamwayi, mutha kugwiritsa ntchito chimango kuchita chilichonse chomwe mungafune kuchita. Pansipa pali magawo asanu apamwamba omwe alipo. Werengani kuti mudziwe zambiri za iliyonse ndikusankha yoyenera pulojekiti yanu. Nawa malangizo ndi zolemba zothandiza kuti mupindule ndi chimango chanu. Ndiye, sankhani chimango chomwe chikugwirizana ndi zosowa zanu ndi bajeti.

Ngati mukupanga tsamba lalikulu kapena pulogalamu yapaintaneti, PHP ndi chisankho chabwino kwambiri. Chifukwa ndi chimodzi mwa zilankhulo zodziwika kwambiri zolembera pa intaneti, Zolinga za PHP zimapangitsa kuti zikhale zosavuta kupanga mapulogalamu a pa intaneti ndi chinenero champhamvu ichi. Kuwonjezera pa kupereka chitukuko champhamvu chilengedwe, Zomangamanga zimachepetsanso kusatetezeka kwa chilankhulo ndikuwongolera kudalirika kwake. Chosavuta chimango chimakhala chosinthika kwambiri. Zomwe zimapereka chithandizo chokwanira cha PHP ndi mitundu yosiyanasiyana ya mapangidwe a mapulogalamu amatha kuchepetsa kwambiri nthawi ndi ndalama zomwe zimakhudzidwa popanga mapulogalamu a pa intaneti..

Scripting languages

PHP is a popular server-side scripting language that allows developers to create dynamic web pages and applications. Chilankhulochi chikhoza kuphatikizidwanso mu HTML kuti zikhale zosavuta kulemba code. Poyamba ankatchedwa PHT, PHP imayimira “Tsamba Lanyumba Lanu,” koma adatchedwanso kuti “Hypertext Preprocessor” kusonyeza chikhalidwe cha chinenerocho. Chilankhulochi chili ndi matembenuzidwe asanu ndi atatu monga a 2022.

PHP ndi yaulere komanso yotseguka. Izi zimapangitsa kuti zikhale zosavuta kwa oyamba kumene kuphunzira kulemba ma code PHP. Komanso ndi open-source, kotero aliyense akhoza kumanga ndi kusintha izo mogwirizana ndi zosowa zawo. PHP ili ndi gulu lotukuka pa intaneti komanso zothandizira kwa opanga. Imathandiziranso zolemba zonse zomveka komanso zopanda nzeru. Ngati mukuganiza zophunzira PHP, Nazi zifukwa zina zoyambira. Mawonekedwe ake osavuta kugwiritsa ntchito apangitsa kuphunzira chilankhulo kukhala kosavuta.

PHP ndi imodzi mwazilankhulo zodziwika bwino za seva, kupanga kukhala kwabwino popanga masamba osinthika. PHP imaperekanso zida zosiyanasiyana. PHP imaphatikizidwa mosavuta mu HTML code ndipo imagwirizana ndi MySQL ndi PgSQL databases. Mutha kupanga pulogalamu yamtundu uliwonse ndi PHP! Ndipo ndizosavuta kusintha ndikusintha chilankhulo. Mwachitsanzo, ngati mukufuna kuwonjezera malo olowera, mutha kungosintha mu PHP!
