Monga wopanga PHP, mutha kukhala mukukhazikitsa mitu pafupipafupi. Mitu iyi imapereka chidziwitso cha seva yanu. Mafayilo a UTF8 alinso ndi a “Byte Order Mark,” kapena BOM. Kuyika mitu yoyamba kumayambitsa magazi, kotero kuchotsa ma BOM pamafayilo anu ndi lingaliro labwino. Kuti mudziwe zambiri, onani Setting Headers mu PHP. Nazi zolakwika zingapo zomwe zimayambitsa magazi:
File_get_contents(): Gwiritsani ntchito izi kuti mutenge zomwe zili mufayilo ya a.txt. Njira imeneyi imafunikanso 'fayilo chogwirira’ ndi ‘text’ parameter. Mafayilo ayenera kukhala okhoza kulemba. The ‘lemba’ value imadziwitsa ntchito ya kuchuluka kwa ma byte mufayilo. Ngati ntchitoyo ikulephera, kulemba() amabwerera zabodza. Komabe, iyi ndi ntchito yofunikira ya PHP.
Zina mwa mapulogalamu otchuka kwambiri a PHP, E-malonda ndi chitukuko cha intaneti ndi zitsanzo ziwiri zodziwika. Chilankhulo cha PHP chimagwiritsidwa ntchito kwambiri m'mabizinesi apaintaneti komanso pamakompyuta. Pali ubwino wambiri wogwiritsa ntchito, kuphatikizirapo kugwiritsa ntchito kwake mosavuta komanso mtengo wake wotsika. Womasulira PHP amakulolani kuti mupange deta yamitundu yosiyanasiyana ndikutumiza ku webserver. Mosiyana ndi zilankhulo zina zolembera, PHP ndi yaulere komanso yotseguka.

PHP idachokera koyambirira kwa zaka makumi asanu ndi anayi ndipo tsopano imagawidwa pansi pa chilolezo cha PHP. PHP-code ndi chilankhulo cholembera chomwe chimayenda pamakompyuta pogwiritsa ntchito machitidwe osiyanasiyana opangira ndi nkhokwe. Monga chilankhulo choyendetsedwa ndi seva yapaintaneti, Ma module owonjezera a PHP amakulolani kuti mupange mawebusayiti pamtengo wotsika kwambiri.
You can include PHP-Dateien in your PHP code by using the syntax ‘include’ kapena amafuna'. Mu PHP, mawu awiriwa amatanthauza chinthu chomwecho – kuphatikiza kapena kufuna. PHP ili ndi ntchito zake zomwe ndizofunikira pakukonza mapulogalamu. Nazi zina mwa izo:
kumanga() ndi bind_once ndi ntchito ziwiri zomwe zimakulolani kumangirira fayilo ku adilesi inayake pa seva musanatumize kwa mlendo.. Komabe, muyenera kugwiritsa ntchito ntchitoyi ngati mukutsimikiza kuti dzina la fayilo ya PHP limakhala lofanana nthawi zonse. Sonderzeichen kapena zilembo zina sizikhoza kuwerengedwa.

Izi zikutanthauza kuti zitha kugwiritsidwa ntchito kupanga mapulogalamu pamapulatifomu osiyanasiyana. Izi ndizothandiza makamaka kwa omwe akugwira ntchito yokhudzana ndi chitukuko cha mafoni. Kusinthasintha kwake komanso kufalikira kumapangitsa kuti ikhale chisankho chabwino kwambiri pamabizinesi.
PHP-Mapulogalamu amagwiritsira ntchito chotolera zinyalala kuchotsa zinthu zomwe sizikufunikanso. Chotolera zinyalalachi ndi chinthu chosavuta kwambiri chomwe chimapangitsa kuti pulogalamu ikhale yosavuta komanso imalepheretsa kuti zinthu zisungidwe ndikugwiritsidwa ntchito mosayenera.. PHP imaphatikizansopo cache, zomwe zimasunga mawu a chinthucho m'malo mochilola kuti chitayike. Kugwiritsa ntchito posungira ndi njira yabwino kwambiri yowonjezerera magwiridwe antchito a mapulogalamu anu a PHP ndikupewa kutayika kwa data.
Kuwonjezera pa kukhala wotchuka chifukwa cha kusinthasintha kwake, PHP imapereka magwiridwe antchito ambiri kwa eni webusayiti. Kuchokera pakuwonetsa zomwe zili patsamba lawebusayiti mpaka kusanthula deta, PHP ndi chiyankhulo chothandizira kwambiri komanso chosinthika chomwe chikukula kwambiri. Kalembedwe kake kosavuta komanso kachitidwe koyenera kamapangitsa kukhala chisankho choyenera kwa opanga mawebusayiti. Ndi chilankhulo chosavuta kugwiritsa ntchito pa seva chomwe chimagwiritsidwa ntchito kwambiri popanga zokha komanso kugwiritsa ntchito intaneti..
The difference between a PHP developer and a web developer is not as great as one might think. PHP ili ndi mfundo zabwino zambiri ndi zina zambiri ndipo imafuna kuti otukula azikhala osinthika komanso osinthika pantchito yawo. Pali zabwino zambiri pakukula kwa PHP komanso kuthekera kwake kugwira ntchito pamapulatifomu osiyanasiyana. Komabe, wotukula akuyeneranso kukhala ndi maluso ndi luso linalake kuti apambane pa ntchitoyi. M'nkhaniyi, tiwona kusiyana kwina pakati pa wopanga PHP ndi wopanga.
Madivelopa ndi opanga mawebusayiti amagwiritsa ntchito zilankhulo zodziwika bwino kupanga mapulogalamu apa intaneti. Zina mwa zilankhulo zimenezi ndi Java, C#, SOAP, JSON, ndi ena.

PHP idapangidwa koyambirira kuti ipangitse mawebusayiti komanso kugwiritsa ntchito intaneti. Chilankhulochi chimatha kuthana ndi chilichonse chomwe pulogalamu ya CGI ingachite, kuphatikiza makeke, masamba amphamvu, ndi zina. Njira yogwiritsira ntchito mwachizolowezi ya PHP ndipamene code imapangidwira pa webserver, ndipo osawoneka ndi msakatuli. PHP entwickler kapena wopanga mapulogalamu nthawi zambiri amakhala wopanga masamba, koma wopanga PHP akhala atakulitsa luso lawo mderali kwa zaka zambiri. Pamenepo, malinga ndi W3Techs, 78.3 maperesenti a masamba amoyo amagwiritsa ntchito chilankhulo cha pulogalamu ya seva. Komanso, 8 kunja kwa 10 mawebusayiti amagwiritsa ntchito PHP mwanjira ina.

PHP imagwiritsidwa ntchito kwambiri ndi opanga mawebusayiti pazinthu zosiyanasiyana. Ngakhale ambiri a iwo amalemba mapulogalamu ndi ma code, ndi mawonekedwe a seva a PHP omwe amapangitsa kuti ikhale yotchuka kwambiri. Madivelopa a PHP amatha kupanga mawebusayiti kuti azigwira ntchito ndi mitundu yosiyanasiyana yamasamba ndikuphatikizanso wina ndi mnzake. Kuphatikiza apo, Madivelopa a PHP amatha kupanga mapulogalamu apa intaneti amakampani ndi mabungwe osapindula. Izi zimapangitsa kuti mabizinesi agwiritse ntchito ukadaulo uwu pazifukwa zosiyanasiyana.
