Ukufunda nokukhohlisa amafayela e-JSON kuwumsebenzi ovamile emhlabeni wokuthuthukiswa kwe-PHP. I-JSON, emele i-JavaScript Object Notation, isiphenduke indinganiso eyamukelwa kabanzi yokushintshisana kwedatha ngenxa yobulula bayo nesakhiwo esinesisindo esincane. Ngaphandle kwegama layo, i-JSON iyifomethi yedatha ezimele yolimi. Lokhu kusho ukuthi singayisebenzisa ngokuphumelelayo ku-PHP kanye nezinye izilimi ezifana ne-JavaScript, C#, Python, njll. Kulo mhlahlandlela, sizobhekisisa ukuthi singayifunda kanjani idatha yefayela le-JSON sisebenzisa i-PHP ngesinyathelo-by- isinyathelo sokuhamba kwekhodi.

I-PHP ihlinzeka ngemisebenzi eyakhelwe ngaphakathi yokuphatha idatha ye-JSON, inxenxa onjiniyela ngobulula nokuhambisana phambili. Kungakhathaliseki ukuthi usebenza kuhlelo lokusebenza oluncane noma uphatha idathasethi enkulu, i-PHP ne-JSON yenza inhlanganisela enamandla.

Ifayela le-phpinfo() liyithuluzi elinamandla elinganikeza ingcebo yolwazi mayelana nendawo yakho ye-PHP. Lolu hlelo lokusebenza lungasetshenziswa ekuxazululeni izinkinga nasekulungiseni amaphutha futhi kuthathwa njengokubalulekile kunoma yimuphi umthuthukisi we-PHP.

Ukufinyelela kudatha yemetha yefayela nokuthola idethi yokudala ifayela kuyingxenye ebalulekile yokuphatha nokuhlela okuqukethwe kwedijithali. Lokhu kungaba usizo kakhulu konjiniyela abakha izinhlelo zokusebenza ezisebenza ngamafayela, njengesistimu yokuphatha okuqukethwe, ama-software okuphatha amafayela nokunye. Ngokuvamile sidinga ukubonisa imininingwane efana nokuthi ifayela ladalwa nini, usayizi wefayela, noma idethi yalo yokugcina yokulungiswa. Ku-PHP, inani lemisebenzi eyakhelwe ngaphakathi iyatholakala engakusiza ukuthi ulande lolu hlobo lwemininingwane yefayela. Kulokhu, sizobe sisebenzisa umsebenzi we-filemtime() ukuze sithole idethi yokudalwa kwefayela.

Impela, ngaziqonda izimfuneko zakho. Nansi indlela i-athikili yakho ethi “PHP Nokuphathwa Kwekheli Le-IP” engabukeka kanje:

Ukusebenza namakheli e-IP emhlabeni wokuthuthukiswa kwewebhu kuwumkhuba ojwayelekile, ikakhulukazi uma usebenzisana nokulandelela komsebenzisi, ukusetha ukuqinisekiswa okusekelwe ku-IP, nokunye okuningi.

Lapho usebenza ne-PHP, inselele eyodwa abathuthukisi abaningi abahlangabezana nayo isidingo sokususa uhla lwemibhalo kanye nemibhalo engaphansi yalo ngokuphindaphindiwe. Lokhu kusebenza kubaluleke kakhulu lapho usebenza nokuphathwa kwefayela kuhlelo lwakho lokusebenza lwe-PHP. Ngenkathi umsebenzi we-rmdir() ku-PHP uhlinzeka ngomsebenzi oyisisekelo wokukhipha umkhombandlela, awusebenzi uma uhla lwemibhalo lungenalutho. Kulokhu, udinga ukususa wonke amafayela nama-subdirectories kuqala. Yilapho ukuphindaphinda kufika khona. Ngalesi sihloko, sibheka kabanzi le nqubo.

Ukufaka i-ext-curl kuwumsebenzi ojwayelekile wonjiniyela abasebenza ku-PHP, ikakhulukazi uma bedinga ukwenza izicelo ze-HTTP ngaphakathi kwezinhlelo zabo zokusebenza. Isandiso sinikeza iqoqo lemisebenzi yokudlulisa idatha kusetshenziswa amaphrothokholi ahlukahlukene. Kuyithuluzi elibalulekile lokusebenzelana nama-RESTful API, ukungena kumawebhusayithi, ukuthumela i-imeyili nge-SMTP phakathi kokunye. Kungakhathaliseki ukuthi uthuthukisa uhlelo lokusebenza lokuhlanganisa okuqukethwe, ithuluzi lokumba idatha, noma uhlelo lokusebenza olulula olusebenzisana nama-API ezinkampani zangaphandle, i-ext-curl ingaba omunye wabasizi bakho abakhulu.

**Umsebenzi we-sigmoid** uwumqondo wezibalo onokusetshenziswa okubanzi emikhakheni efana nokufunda komshini, ukufunda okujulile, nesayensi yedatha, ngenxa yezici zayo ezihlukile zokwenza okukhiphayo kube okujwayelekile phakathi kwebanga elingu-0-1. Umsebenzi we-sigmoid ubalulekile ikakhulukazi ekuhlehleni kwezinto kanye namanethiwekhi okwenziwa kwemizwa, lapho usiza ukunikeza okungenzeka, usize izibikezelo ezinembe kakhulu.

Indawo yesihloko iyithuluzi elinamandla ku-PHP. Inikeza onjiniyela indlela ephumelelayo yokulawula ukuhamba kwezinhlelo zabo zokusebenza zewebhu. Lesi sihloko sizohlola kahle lo msebenzi, siveze izinkinga zawo, izixazululo, kanye nezinyathelo ezidingekayo zokuwusebenzisa ngendlela efanele ukuze usebenze kahle.
