Mitauro yekuronga yakanangana nechinhu inoshandisa makirasi kuronga data nenzira ine musoro. Kirasi yega yega inomiririra imwe mhando yedata. Makirasi ane nzira uye hunhu uye anoshandiswa sehwaro hwekudyidzana kwechinhu. Iwo makirasi anoshandiswa kuenzanisira yakaoma data mhando. Kusiyana neakareruka datatypes anoshandiswa mune yechinyakare PHP kodhi, OOP inobvumira huwandu hune musoro hwe data.

Object-oriented programming inzira huru yekuita kuti kodhi yako ive nyore kuchengeta. Unogona kushandisazve kodhi uye kushandisazve zvikamu pasina kunetsekana nazvo zvichipokana. Izvi zvinonyanya kubatsira kana uchishanda pane yakakura, yakaoma zvikumbiro. Kushandisa Object-Oriented programming kuchaita kuti zvive nyore kuchengetedza uye kushandisazve kodhi.

Mabhenefiti ezvirongwa zvinonangana nezvinhu zvakawanda. Iyo inokutendera iwe kutarisana nematambudziko akaomarara nekuunza nhanho nyowani yekubvisa kune yako kodhi. Izvi zvinoitwa nekuparadzanisa kodhi mumakirasi akasiyana. Aya makirasi ane chaiwo datatypes uye maitiro anogona kugadziridzwa kana kushandiswa zvakare kune akasiyana zvinangwa.

Kuronga-kwakanangana nechinhu inzira huru yekugadzira ine simba pawebhu maapplication. Iyo ine zvakawanda zvakanyanya kuchinjika kupfuura HTML, uye zviri nyore kudzidza nekushandisa. Iyo zvakare yakanakisa sarudzo yekuvaka yega bhizinesi software. Pamusoro pekugadzira webhusaiti ine simba, PHP inobvumidza iwe kugadzira yakajairwa software yakasarudzika kune yako kambani.

Kurongwa-kwakanangana nechinhu muPHP kunobvumidza iwe kuparadzanisa makirasi ako kubva kune mumwe. Panzvimbo yekuve nekirasi imwe hombe uye akati wandei madiki, unogona kuva nemakirasi akasiyana uye nzira dzekirasi yega yega. Semagumo, kodhi yako iri nyore kuchinjika, zvakanyanya kurongeka, uye zvakanyanya kushanda zvakanaka. Iyo zvakare inobvumidza iwe kubata kodhi yako zvirinani.

Nzira yakanakisa yekutsvagira mutauro wakakodzera wakasarudzika ndeyekubvunza netiweki yako. Kana iwe uchitova nedhigirii mumunda une chekuita nesainzi yekombuta, unogona kubvunza vamwe vako kuti ndeupi mutauro wechirongwa wavanoshandisa. Vanogona kukwanisa kukupa mamwe matipi kana kukuudza nezve hunyanzvi mitauro yekuronga iwe yaunogona kudzidza wega. Iwe unogona zvakare kutsvaga zvinzvimbo paStellenanzeigen kuti uone kuti ndeipi mitauro uye musanganiswa uri kudiwa.

Kuwedzera PHP, iwe unogona zvakare kushandisa mimwe mitauro yekuronga. Ruby mumwe wavo. Zvisinei, mutauro uyu une zvimwe zvinokanganisa. Semuyenzaniso, Ruby inononoka. Ruby anoshandisa datatypes ane simba.
