Chaunoda kuziva nezvePP purogiramu

Kana iwe uri kufunga kugadzira chirongwa chewebhu, ungangoda kudzidza zvakawanda nezve PHP programmierung. Kune zvakawanda zvakanakira mutauro uyu, kusanganisira mukurumbira wayo pakati pewebhu masangano uye kuenzanisa kwayo. PHP isarudzo yakanaka kune vanotanga, sezvo ichibvumira vagadziri vewebhu kugadzira mapeji ewebhu ane simba zviri nyore uye pasina kupokana kwakawanda. Chinyorwa chinotevera chichatsanangura PHP, Symfony, uye Object-oriented programming.

Symfony

Kana iwe uchitsvaga chimiro chekugadzira mawebhu application, Symfony isarudzo yakakurumbira. Chinangwa chikuru chechimiro ichi ndechekurerutsa maitiro ekusimudzira, uye inobvisawo mabasa ekudzokorora. Kunyangwe isingauye nepaneru admin, Symfony ine yakazara seti yezvinhu zvinogona kushandiswazve, PHP maraibhurari, uye yakasimba dhairekitori chimiro. Izvi zvinoreva kuti kodhi yako ichave yakajeka uye inoverengwa, uye ichaita kuti hurongwa hwekuvandudza.

Sezvimwe nemamwe mafuremu, Symfony yakagadzirirwa kubatsira vanogadzira kuvaka mawebhu application nekuvagonesa kushanda nemodhi-view-controller (MVC) zvivakwa. MVC dhizaini inoita kuti iwe uise pakati magadzirirwo, uye haufanirwe kugadzirisa zvidimbu zvakakura zvekodhi. Iyo dhizaini zvakare inoita kuti zvive nyore kubata saiti nekubvisa zvisina kufanira maseru uye kuita kuti kugadzirisa kuve nyore. Symfony's modhi-view-controller architecture uye nzira system inoita kuti zvive nyore kuvaka ese web applications.

Kunyangwe kuve open-source, Symfony inotsigirwa nekutengeserana. Vagadziri vayo vane kuzvipira kwakasimba kuhurongwa uye vanoitsigira nemisangano uye zvidzidzo zvepamutemo. Zvakatowanda, nharaunda yevagadziri vehurongwa inoshanda zvakanyanya, uye inototsigirwa nekambani huru inodyidzana, SensioLabs. Semagumo, kune akawanda maprofessional level conferences, tutorials, uye zvitupa zvevagadziri veSymfony.

PHP

PHP ndeimwe yeanonyanya kufarirwa server-side scripting mitauro. Yakagadzirwa naRasmus Lerdorf, PHP inoshandiswa nevanopfuura 240 miriyoni mawebhusaiti uye pamusoro 2 miriyoni internet maseva. Kare 20 makore, PHP yakadzokororwa kakawanda kuti irambe iripo uye inoshanda. Nhasi, PHP inoshandiswa kugadzira akasiyana marudzi ewebhusaiti, senge mablog blog, maforamu, uye maakaundi emushandisi. Iwe unogona nyore kudzidza kunyora PHP kodhi kuvaka yako webhusaiti.

Mutauro wekunyora uyu unogona kushandiswa kune marudzi ese ezvinangwa. Inoshandiswa zvakanyanya mukuvandudza webhu uye inoshandiswa kuvaka yakapusa data processing application. PHP inoenderana neMySQL, yemahara database server. Iyo zvakare inobvumidza iwe kutumira kunze data yakachengetwa pane yako server. Iwe unogona kudzidza kushandisa PHP nhasi nekutora PHP kosi. Pane zvakawanda zvinobatsira pakudzidza PHP. Mashoko anotevera akaitirwa kukubatsira kuti utange. Funga nezvebasa muPHP nhasi!

Imwe bhenefiti huru yePHP kugona kwayo kugadzirisa mushandisi kupinza. Nepo HTML isingakwanise kubata rudzi urwu rwekuisa, PHP inogona. Nekushandisa tekinoroji iyi, unogona kushandura mapeji eHTML kuita PHP, wobva waaisa kune server uye wovakumbira pasina kuachinja. Izvi zvinoita kuti PHP ive chishandiso chikuru cheE-Commerce. Kana yashandiswa nemazvo, PHP inogonawo kushandiswa kugadzira zvinyorwa zvinogadzirwa nemushandisi senge mafaera ePDF, Flash animations, uye HTML mafaira. Uyezve, PHP zvakare inobvumidza iwe kuchengetedza mafaera ako akagadzirwa uchishandisa server-padivi cache.

Kuronga-kwakanangana nechinhu

Imwe pfungwa yakakosha muObject-yakatarisana PHP programming iri kushandisa muvaki wekirasi yevabereki. Dzimwe nguva, zvingave zvisingakwanisi kudana muvaki wekirasi yevabereki paunenge uchigadzira chinhu. Pakadaro, unogona kufonera muvaki wekirasi yevabereki nekushandisa scope resolution opareta “.:”. Iyi nzira inogona kugamuchira nharo imwe chete kana dzakawanda. Muvaki ndiyo nzira huru yechinhu. Inonzi muvaki nokuti inoshanda sepurani yekugadzira zvinhu zvitsva.

Chikamu chekutanga cheObject-oriented PHP programming inosanganisira kugadzira mainterface. Iyo interface imhando yakakosha yekirasi inobvumira vanogadzira kutsanangura nekugadzira yavo zvirongwa. Yakafanana nekirasi kunze kwekuti haina muviri. Iyo interface inogona kugadzirwa uchishandisa iyo interface kiyi muPHP. Inogonesa vagadziri vekirasi kuti vawedzere nzira dzeveruzhinji pasina kuita. Mukupesana ne, interface inogona kusiyaniswa kubva mukirasi uye inogona kuva neanopfuura muenzaniso mumwe.

MuObject-yakatarisana PHP programming, kirasi inoputira yakapihwa munhu, mhuri, nemamwe mazita. Pamusoro pe, tsika yakanaka yeOO ndeyekufumura minda yakavanzika kuburikidza neruzhinji nzira dzinonzi accessors. Izvi zvinopa veruzhinji nzira iri nyore yekuwana ruzivo mukirasi yePHP. Nenzira iyi, iwe unogona kuchengetedza chimiro chimwe chete pasina kugadzirisa kodhi yako. Kuronga-kwakanangana nechinhu PHP kunorerutsa maitiro ekugadzira mawebhusaiti.

Procedural programming

Pane nzira mbiri dzekugadzirisa komputa: muitiro uye chinonangana nechinhu (OOP). Nepo procedural kodhi iri sarudzo yakanaka kune vanotanga, haisi sarudzo yakanaka kune nyanzvi. Procedural PHP kodhi inotevera mamwe emisimboti yakafanana neOOP, sekushandiswa kwezvinhu uye nzira. Munzira kodhi, nhanho imwe neimwe inoita basa rakati. Kushandisa pateni kana chunk yekodhi, procedural coding inotevera misimboti yekumisikidza-yakatarisana nechirongwa.

PHP mutauro wemaitiro. Semagumo, haishandisi chero maitiro, izvo zvinoita kuti zvive nyore kugadzira maapplication. Nepo PHP inoshandisa procedural programming, mazhinji emakirasi ayo akanyorwa nemutauro unonzi C. Zvisinei nekuti anotanga anotora nzira ipi, procedural code inovabatsira kugadzira hwaro hwakasimba hwemapurojekiti emangwana. Uye chero bedzi vachinzwisisa nheyo dzemutauro, ivo vanozokwanisa kugadzira inoshanda maapplication pasina nguva.

Imwe nheyo yakakosha yehurongwa hwehurongwa ndeye DRY, kana “usazvidzokorora”. Izvi zvinoreva kuti haufanirwe kudzokorora kodhi kunze kwekunge zvichidikanwa. Pane kudaro, iwe unofanirwa kuisa kodhi yakajairika munzvimbo inogona kushandiswazve. Munzira kodhi, iyo kodhi imwechete inogona kuoneka kakawanda munzvimbo dzakasiyana. Zvakafanana zvinoenda kune zvinhu. Kodhi yakanangana nechinhu iri nyore kuchengetedza nekugadzirisa. Iyi itsika yakanaka kune chero PHP mugadziri.

Frameworks

Kunyangwe iwe uri kuvaka application yemutengi, kana kuti uri kutsvaga kurerutsa maitiro ekuvandudza, PHP zvirongwa zvekugadzira zvinogona kuita kuti maitiro ave nyore. PHP masisitimu anopa pre-akavakwa mamodule uye nheyo dzinotora yakawanda inonetesa coding kubva mundiro yako.. Pakusarudza imwe, funga zvinodikanwa zvepurojekiti yako. PHP masisitimu ane madhigirii akasiyana ekutsigirwa kwepamutemo, tsigiro yenharaunda, uye zvinyorwa. Pakupedzisira, iwe unofanirwa kusarudza chimiro chinoenderana nezvido zvako.

Anoverengeka PHP programming masisitimu aripo, asi pane mashoma akakurumbira aunogona kusarudza kubva. Sezvineiwo, unogona kushandisa hurongwa kuita zvese zvaungade kuita. Akanyorwa pazasi ndiwo makuru mashanu masisitimu aripo. Verenga kuti udzidze zvakawanda nezve imwe neimwe uye sarudza yakakodzera yeprojekti yako. Heano mamwe matipi anobatsira uye zvinyorwa zvekukubatsira kuti unyatso shandisa chimiro chako. Zvadaro, sarudza hurongwa hunoenderana nezvido zvako uye bhajeti.

Kana iwe uchigadzira yakakura-chiyero webhusaiti kana webhu application, PHP isarudzo yakanaka. Nekuti ndeimwe yemitauro inonyanyozivikanwa yekunyora paInternet, PHP masisitimu anoita kuti zvive nyore kuvaka mawebhu application nemutauro une simba uyu. Pamusoro pekupa nzvimbo ine simba yekusimudzira, mafuremu zvakare anoderedza kusakanganiswa kwemutauro uye anovandudza kuvimbika kwawo. Iyo yakapfava dhizaini ndiyo inowanzoita zvakawanda. Idzo dzinopa rutsigiro rwakakwana rwePHP uye akasiyana-siyana ekugadzira software mapatani anogona kuderedza zvakanyanya nguva uye mari inosanganisirwa mukugadzira web applications..

Mitauro yekunyora

PHP yakakurumbira server-side scripting mutauro unobvumira vanogadzira kugadzira mapeji ewebhu ane simba uye maapplication. Mutauro unogonawo kuiswa muHTML kuti zvive nyore kunyora kodhi. Pakutanga yainzi PHT, PHP inomirira “Peji Yekumba Yemunhu,” asi rakatumidzwa zita rokuti “Hypertext Preprocessor” kuratidza chimiro chemutauro. Mutauro une shanduro sere se 2022.

PHP ndeyemahara uye yakavhurika-sosi. Izvi zvinoita kuti zvive nyore kune vanotanga kudzidza kunyora PHP kodhi. Iyo zvakare yakavhurika-source, saka chero munhu anogona kuivaka nekuigadzirisa kune zvavanoda. PHP ine nharaunda inobudirira yepamhepo uye zviwanikwa zvevagadziri. Iyo inotsigirawo zvese zvine musoro uye zvisina-rational databases. Kana uri kufunga kudzidza PHP, hezvino zvimwe zvikonzero zvokutanga. Yayo mushandisi-inoshamwaridzika interface ichaita kuti kudzidza mutauro kuve nyore.

PHP ndeimwe yeanonyanya kufarirwa server-side scripting mitauro, zvichiita kuti ive yakakwana pakugadzira mapeji ewebhu ane simba. PHP inopawo zvakasiyana-siyana zvezviridzwa. PHP inosanganiswa nyore nyore muHTML kodhi uye inoenderana neMySQL uye PgSQL dhatabhesi. Iwe unogona kugadzira chero mhando yewebhu application nePHP! Uye zviri nyore kugadzirisa uye kugadzirisa mutauro. Semuyenzaniso, kana iwe uchida kuwedzera nzvimbo yekupinda, unogona kungoichinja muPHP!
