Umehluko Phakathi Konjiniyela be-PHP nama-PHP Entwicklers

I-PHP iwulimi lokubhala oluhlala lusesimweni sokuziphendukela kwemvelo futhi lusetshenziselwa ukwenza imisebenzi eminingi. Abathuthukisi be-PHP bakha izakhiwo zedatha eyinkimbinkimbi kanye nezinhlelo zokusebenza zewebhu. Ngokuvamile zisetshenziswa ezinhlelweni zokuphatha okuqukethwe, guestbookers, kanye nezinkundla. Ngokuvamile bagcina bethuthukisa okuqukethwe okunamandla. Ukuze ufunde kabanzi nge-PHP, qhubeka ufunda! Lesi sihloko sihlola umehluko phakathi konjiniyela nabathuthukisi be-PHP. Ukuqala, cabangela indima yakho njengonjiniyela.

Amafayela kumafayela we-PHP

Njengonjiniyela we-PHP, ungase uhlele izihloko njalo. Lezi zihloko zinikeza ulwazi lweseva yakho. Amafayela e-UTF8 nawo aqukethe i-a “I-Byte Order Mark,” noma i-BOM. Ukubeka izihloko kuqala kubangela igazi, ngakho-ke ukususa ama-BOM kumafayela akho kuwumqondo omuhle. Ukuze uthole ulwazi olwengeziwe, bona Ukusetha Izihloko ku-PHP. Nawa amaphutha ambalwa avamile abangela igazi:

Ifayela_thola_okuqukethwe(): Sebenzisa lo msebenzi ukuze uthole okuqukethwe kwefayela le-a.txt. Le ndlela futhi idinga 'isibambo sefayela’ kanye ‘nombhalo’ ipharamitha. Amafayela kufanele akwazi ukubhala. The ‘loba’ inani lazisa umsebenzi wenani lamabhayithi kufayela. Uma ukuhlinzwa kwehluleka, bhala() ibuyisela amanga. Nokho, lokhu kuwumsebenzi obalulekile we-PHP.

Phakathi kwezinhlelo zokusebenza ezisekelwe ku-PHP ezaziwa kakhulu, I-e-commerce nokuthuthukiswa kwewebhu yizibonelo ezimbili ezijwayelekile. Ulimi lwe-PHP lusetshenziswa kakhulu emabhizinisini aku-inthanethi nakumakhompyutha omuntu. Ziningi izinzuzo zokuyisebenzisa, okuhlanganisa nokusebenziseka kwayo kalula kanye nenani layo eliphansi. Umhumushi we-PHP ikuvumela ukuthi udale idatha yezinhlobo ezahlukahlukene futhi uyithumele kuseva yewebhu. Ngokungafani nezinye izilimi zokubhala, I-PHP ingumthombo wamahhala futhi ovulekile. Ukwazi izisekelo ze-PHP kubalulekile lapho uzethula ku-IT-Recruiters.

Uhlelo lwe-PHP luzosebenza kumaseva ewebhu aziwa kakhulu. Ulimi lokubhala i-PHP lusetshenziselwa ukwakha amawebhusayithi ashukumisayo nezinhlelo zokusebenza zewebhu. I-PHP inemvelaphi yayo ekuqaleni kweminyaka engamashumi ayisishiyagalolunye futhi manje isatshalaliswa ngaphansi kwelayisensi ye-PHP. I-PHP-code iwulimi lokubhala olusebenza kumakhompyutha kusetshenziswa amasistimu wokusebenza ahlukahlukene kanye nesizindalwazi. Njengoba kuwulimi oluqhutshwa yiseva yewebhu, Amamojula wokunweba we-PHP akuvumela ukuthi uthuthukise izinhlelo zokusebenza zewebhu ngezindleko eziphansi kakhulu.

Ukusebenza kwamafayela we-PHP

Ungafaka i-PHP-Dateien kukhodi yakho ye-PHP ngokusebenzisa i-syntax 'include’ noma udinga'. Ku-PHP, lawa magama amabili asho into efanayo – hlanganisa noma dinga. I-PHP inesethi yayo yemisebenzi ebalulekile ekuhleleni. Nazi ezinye zazo:

bopha() futhi i-bind_once yimisebenzi emibili ekuvumela ukuthi ubophe ifayela ekhelini elithile kuseva ngaphambi kokulithumela kusivakashi.. Nokho, kufanele usebenzise lo msebenzi kuphela uma uqinisekile ukuthi igama lefayela le-PHP lihlala lifana. I-Sonderzeichen noma ezinye izinhlamvu zingase zingafundeki. Kufanele futhi uqinisekise ukuthi i-PHP-Programm yakho aweqi umkhawulo ngoba izonqamuka.

Umsebenzi we-file_put_contents ungasetshenziswa ukufunda noma ukubhala idatha efayeleni. Lo msebenzi wamukela iyunithi yezinhlamvu, igama lefayela, futhi i-charset futhi idale ifayela elisha.txt. Usayizi wefayela() izobuyisela inani lamabhayithi efayelini. Ingasetshenziswa futhi ukufunda noma ukubhala ifayela. Ingasetshenziselwa ukufunda nokubhala idatha, noma ingasetshenziswa ukwakha ifayela.

Ngaphandle kokuthi ikhodi ikufayela le-PHP, ungasebenzisa futhi isandiso esikhethekile ukuze ungeze ukusebenza. Ngokungafani nolimi olujwayelekile, Imisebenzi ye-PHP-tag ikuvumela ukuthi wengeze noma ususe amathegi e-HTML, ngalokho kushintsha umongo. Lokhu kungenza kube lula ukusebenzisa izandiso, njenge-jQuery. Kungenjalo, ungasebenzisa isandiso esihlukile se-jQuery. Uma ukhetha inketho yokugcina, kufanele uqiniseke ukuthi unenguqulo ye-PHP.

Ukusebenza kwezinhlelo ze-PHP

Izinhlobonhlobo zemisebenzi zingenziwa ezinhlelweni ze-PHP. Ku-PHP 5, lo msebenzi wethulwa. I-PHP iphinde isekele i-Object-Oriented Programming. Izinto empeleni akuzona izinto, kodwa ubheke eziguquguqukayo nezibambi. Lesi sici sivumela onjiniyela ukuthi bakhe izinto ezingasetshenziswa ukwenza imisebenzi eyahlukene. I-PHP isekela Ukufinyelela Kwedatha Egxile Entweni (I-PDO).

Njengolimi lwezinhlelo olusetshenziswa kakhulu, I-PHP idume kakhulu emhlabeni. Ingasetshenziselwa ukwakha izinhlelo zokusebenza ezisuselwe kwideskithophu kanye nezinhlelo zokusebenza zewebhu nge-graphic interface yomsebenzisi. I-PHP iphinde isekele ukuthuthukiswa kwe-cross-platform. Lokhu kusho ukuthi ingasetshenziswa ukuthuthukisa izinhlelo zokusebenza kuzo zonke izinkundla ezahlukene. Lokhu kuwusizo ikakhulukazi kulabo abasebenza kuphrojekthi ehilela ukuthuthukiswa kwamaselula. Ukuvumelana nezimo nokunwebeka kwayo kuyenza ibe ukukhetha okuhle kakhulu kwezinhlelo zebhizinisi.

I-PHP-Izinhlelo zisebenzisa umqoqi wezibi ukuqeda izinto ezingasadingeki. Lesi siqoqi sikadoti siyisici esilula kakhulu esenza kube lula ukuhlela futhi sivimbele izinto ukuthi zigcinwe futhi zisetshenziswe ngokungadingekile.. I-PHP ifaka nesici senqolobane, egcina ireferensi yento esikhundleni sokuyivumela ukuthi ilahleke. Ukusebenzisa inqolobane kuyindlela enhle kakhulu yokwandisa ukusebenza kwezinhlelo zakho ze-PHP futhi uvimbele ukulahleka kwedatha.

Ngaphezu kokuduma ngokuhlukahluka kwayo, I-PHP inikeza ukusebenza okuningi kubanikazi bewebhusayithi. Kusukela ekuboniseni okuqukethwe ekhasini lewebhu kuya ekuhlaziyeni idatha, I-PHP iwulimi lokuhlela olusebenza kahle kakhulu futhi oluguquguqukayo oluya luduma kakhulu. I-syntax yayo elula kanye nokusebenza okunengqondo kuyenza ibe inketho ekahle kubathuthukisi bewebhusayithi. Iwulimi lokuhlela ohlangothini lweseva olusebenziseka kalula olusetshenziswa kakhulu ukwenza okuzenzakalelayo nezinhlelo zokusebenza zewebhu..

Umehluko phakathi konjiniyela nabathuthukisi

Umehluko phakathi komthuthukisi we-PHP nomthuthukisi wewebhu awumuhle ngendlela umuntu angacabanga ngayo. I-PHP inamaphuzu amaningi amahle nama-nuances futhi idinga ukuthi abathuthukisi bavumelane nezimo futhi basebenzise izinto ezihlukahlukene emsebenzini wabo. Kunezinzuzo eziningi ekuthuthukisweni kwe-PHP kanye nekhono layo lokusebenza kumapulatifomu ahlukene. Nokho, umthuthukisi kufanele futhi abe namakhono athile nolwazi ukuze aphumelele kule ndima. Kulesi sihloko, sizobheka omunye umehluko phakathi konjiniyela we-PHP kanye nonjiniyela.

Abathuthukisi nabaklami bewebhu basebenzisa izilimi zokuhlela ezidumile ukuze bakhe izinhlelo zokusebenza zewebhu. Phakathi kwalezi zilimi kukhona i-Java, C#, INSIPHO, JSON, nabanye. Abahlaziyi be-Middleware baphinde baphathe ama-backups azenzakalelayo futhi bagcine amasistimu nolwazi olugciniwe. Umehluko phakathi konjiniyela nomklami wewebhu awukho olimini kuphela, kodwa nakumakhono nolwazi lwabathuthukisi. Umthuthukisi we-PHP uzojwayele ukujwayelana nakho konke okungenhla.

I-PHP yenzelwe ukuthuthukiswa kwewebhu kanye nezinhlelo zokusebenza zewebhu. Ulimi lungaphatha yonke into engenziwa wuhlelo lwe-CGI, kuhlanganise amakhukhi, amakhasi ashukumisayo, futhi nokuningi. Lokhu kusetshenziswa kwendabuko kwe-PHP kulapho ikhodi idalwe khona kuseva yewebhu, futhi ayibonwa isiphequluli. I-PHP entwickler noma umthuthukisi ngokuvamile uzoba umthuthukisi wewebhu, kodwa umthuthukisi we-PHP uzobe ethuthukise amakhono abo kule ndawo iminyaka. Empeleni, ngokusho kwe-W3Techs, 78.3 amaphesenti amawebhusayithi abukhoma asebenzisa lolu limi lokuhlela oluseceleni kweseva. Ngaphezu kwalokho, 8 koku 10 amawebhusayithi asebenzisa i-PHP ngandlela thile.

Izindleko zonjiniyela we-php

Kunezindlela eziningi ongakhetha kuzo uma udinga umthuthukisi we-PHP. Ungaqasha isisebenzi esizimele noma inkampani ukuthi ikuqashe. Abathuthukisi abazimele akudingeki ukuthi baqashwe yinkampani, futhi ungawaqasha kuphela uma uwadinga. Ama-freelancers nawo akhokhisa imali engaphansi kwesisebenzi senkampani, futhi ungawaqasha noma nini lapho uwadinga. Uma ufuna unjiniyela we-PHP ngesisekelo senkontileka, uzodinga ukwazi ukuthi uzimisele ukukhokha malini.

Abathuthukisi be-PHP bangenza noma kuphi $15 ngehora ukuze $80 ngehora. Lapho benolwazi oluthe xaxa, amanani abo azoba phezulu. Kungenjalo, uma uqasha unjiniyela wephrojekthi yesikhathi eside, ungacabanga ukuqasha umuntu ongaphandle kwe-US. Kulezi zimo, ungalindela ukukhokha kancane kakhulu kunalokho obungakukhokhela umthuthukisi waseMelika. Amanani angase abe ngaphansi. Kuzodingeka ucabangele indawo yakho lapho ufuna unjiniyela we-PHP.

Ulimi lwe-PHP lunamaphuzu amaningi amahle nama-nuances. Ukuqasha unjiniyela onamakhono athile kungakusiza ugweme ukuqasha unjiniyela osezingeni eliphansi. Abathuthukisi be-PHP badinga ukunethezeka ngezitayela ezahlukahlukene zomsebenzi, kuhlanganise nalawo amakhasimende abo. Bazodinga futhi ukuqeqeshwa okukhethekile, ngaphandle uma besebenza kuphrojekthi engadingi i-PHP. Futhi abathuthukisi be-PHP badinga ukuba nekhono eliphakeme. Uma udinga unjiniyela we-PHP, ungangabazi ukuxhumana ne-Spider India. Ithimba lochwepheshe lizokwenza umsebenzi wenziwe ngokushesha nangempumelelo.

Kungani ukhetha umthuthukisi we-php?

Kungani kufanele uqashe umthuthukisi we-PHP wewebhusayithi yakho entsha? Ngemva kwakho konke, inqubo yokwakha iwebhusayithi yakho ihilela umsebenzi omningi wezobuchwepheshe. Awufuni ukukhokha imali eshisiwe ukuze nje umthuthukisi wewebhu athuthukise okulula, iwebhusayithi engabonakali – ufuna ukwenza umsebenzi wenziwe kahle. Kodwa kunezimfanelo ezimbalwa okufanele uzibheke ukuze uqinisekise ukuthi uthola umthuthukisi wewebhu ongcono kakhulu womsebenzi.

Okokuqala, Abathuthukisi be-PHP bangochwepheshe ekuthuthukiseni izinhlelo zokusebenza zewebhu ezinamandla. Kufanele bazi ukuthi bangasebenza kanjani eqenjini futhi bathuthukise amawebhusayithi amasha. Amakhono abo kufanele ahlanganise i-HTML neJavaScript. Kufanele futhi bazazi izindlela zesimanje zentuthuko. Uma unesizinda sobuchwepheshe, kufanele ukwazi ukufunda umtapo wezincwadi we-PHP futhi uqonde ulimi. Ekugcineni, Abathuthukisi be-PHP badinga ukwazi ukuzivumelanisa nanoma yiziphi izinguquko zedizayini, ngakho kufanele bakwazi ukusebenzisana kahle nobunye ubuchwepheshe.

I-PHP isetshenziswa kakhulu ngabathuthukisi bewebhu ezinhlobonhlobo zezinhlelo zokusebenza. Ngenkathi iningi labo libhala isoftware nekhodi, izici ze-server-side ze-PHP ezenza idume kakhulu. Abathuthukisi be-PHP bangenza amawebhusayithi asebenze nezinhlobo ezahlukene zamawebhusayithi futhi baze bawahlanganise kwelinye. Ngaphezu kwalokho, Abathuthukisi be-PHP bangakha izinhlelo zokusebenza zewebhu zangokwezifiso zezinkampani nezinhlangano ezingenzi nzuzo. Lokhu kwenza ukuthi amabhizinisi akwazi ukusebenzisa lobu buchwepheshe ngezinjongo ezahlukahlukene.
