Kutheni kufuneka ufunde PHP Programmierung

I-PHP lulwimi olunamandla lokubhala. Ngokungafaniyo nezinye iilwimi zokubhala, PHP doesn’t require a browser or server to function. Izikripthi ze-PHP zingasetyenziselwa ukusetyenzwa okubhaliweyo okulula okanye iinkqubo zecron. I-PHP ikwane-syntax ekulula ukuyisebenzisa. Ukwengeza, Imibhalo ye-PHP kulula ukuyigcina kunye nokukala.

Ulwimi lwenkqubo olujolise kwinjongo (OOP)

Inkqubo eJoliswe kwiNjongo (OOP) sisimbo senkqubo esisebenzisa iiklasi kunye nezinto ukulinganisa idatha. Nje ngeziphumo, ilungele iinkqubo ezinkulu ezifuna ulondolozo olusebenzayo kunye neengqiqo ezinzima. Ngokusebenzisa esi simbo, abadwelisi benkqubo banokongeza umsebenzi owongezelelweyo ngaphandle kokukhathazeka ngokubhala ikhowudi eninzi.

I-OOP kwi-PHP yenza abaphuhlisi bachaze iiklasi ezimele izinto kwinkqubo. Izinto zingasetyenziselwa ukugcina, buyisa, lungisa, kwaye ucime ulwazi. Ezi klasi kunye nezinto zingasetyenziselwa kwakhona ngeenjongo ezahlukeneyo. Ngelixa i-OOP ingazifanelanga iingxaki ezincinci, igcina ixesha labaphuhlisi.

Udweliso lwenkqubo olujolise kwinjongo sisakhono esiyimfuneko kumdwelisi wenkqubo onothando lwezicelo ezibanzi. Ngelixa i-PHP ilulwimi olusebenzayo kunye ne-prozedural, Kananjalo inecandelo elikhulu elijolise kwinto. Ikhosi ye-OOP elungileyo iya kukunceda ukuba ufunde iziseko zale ndlela yokucwangcisa kwaye uphuhlise izakhono eziphambili.

Ngelixa i-OOP ingeyomfuneko kuzo zonke iindidi zeenkqubo, yenza udweliso lwenkqubo lube lula kwaye lukhawuleze. I-Object-orientation ivelisa ngaphezulu kwaye ayifanelekanga kuzo zonke iindidi zeenkqubo. Abanye abadwelisi benkqubo bakhetha ukuphuhlisa izicelo kunye neendlela zenkqubo zokunciphisa i-overhead. Kwakhona kubalulekile ukwazi ukuba i-OOP ingasetyenziswa kwiinkqubo ngaphandle kokuguqula ikhowudi yesakhiwo.

Schnelle Leistung

Programming is an essential skill to have in today’s modern world. Uninzi lwethu lusebenzisa usetyenziso lwewebhu ngeenjongo ezahlukeneyo.
