Funda Izisekelo Zohlelo lwe-PHP

I-PHP-Tutorial iqala ngesingeniso esilula sokwenza izinhlelo ku-PHP. It then proceeds to teach you HTML and CSS as well. Uzobe usendleleni yokuba ngumhleli wezinhlelo onekhono. Kodwa ngaphambi kokuthi uqale, kubalulekile ukwazi izisekelo zokuhlela ngaphambi kokuthi uqhubekele kumasu athuthuke kakhulu. Nawa amanye amathiphu ukuze uqale:

Object-Orientierte Programmierung

In Object-Oriented PHP Programmierung, amakilasi ayizisekelo zokwakha ulimi lokuhlela. Lawa makilasi amele uhlobo oluthile lwedatha. Into ingaba yinto eguquguqukayo, umsebenzi, ukwakheka kwedatha, noma inani. Lapho udala ikilasi, ingxenye yokuqala yegama igama elingukhiye elisha, bese igama lekilasi liyisiqalo. Lesi siqalo sisetshenziselwa ukwakha izinto ezintsha, ezibe sezigcinwa eziguquguqukayo. I-Object ingaba nezakhiwo nezindlela.

I-OOP yindlela yokuhlela kabusha umhlaba ube yizinhlobo eziningi zezindawo zokusebenzelana. Ngokwesibonelo, ungabhala iskripthi esisebenzisa imisebenzi ukuze ubuze isizindalwazi noma wenze iwebhusayithi. Le ndlela yaziwa ngokuthi i-polymorphism. Izinto zingashintshwa, okusho ukuthi ikhodi efanayo ingasebenza ezintweni ezahlukene. Uhlelo lungakhiwa izinto eziningana, futhi into ngayinye izoba nomsebenzi ohlukile.

Typo3

If you’re new to TYPO3 and PHP coding, khona-ke kufanele ufunde lesi sihloko. I-Typo3 iyi-CMS eyinkimbinkimbi enezici eziningi, kodwa amathuluzi ambalwa. I-Plugin Directory yayo nayo incane, uma kuqhathaniswa ne-WordPress namanye ama-CMS adumile. Le CMS isineminyaka eminingi ikhona futhi isineminyaka eminingi ikhona. Nokho, kubalulekile ukuqonda ukuthi akuyona a “uhlaka” njenge-WordPress, futhi idinga ukunakekelwa okuqhubekayo ukuze ihlale isebenza.

Imisebenzi ye-TYPO3 CMS ibhalwe nge-PHP. I-syntax ifana ne-PHP, futhi lokhu kuvumela izandiso nokulungiswa. Ukusebenza kwe-XCLASS kukuvumela ukuthi ubhale amakilasi nezindlela. I-TypoScript iphinde isetshenziselwe ukulungiselelwa kwe-backend. Ngenjwayelo, isebenzisa i-syntax efanayo ne-TYPO3, kodwa ukufaka amakhodi kuhluke kancane. I-TYPO3 isebenzisa isistimu yefayela ebizwa ngokuthi i-TSconfig kukho kokubili ukuhlelwa kwe-backend ne-frontend.

PHP

Learn about PHP and its basics with these tutorials. I-PHP iwulimi lokuhlela oluguquguqukayo olungasebenza kunoma iyiphi iseva yewebhu futhi lungasetshenziswa ukwakha noma yiluphi uhlobo lwewebhusayithi. Lolu limi lombhalo womthombo ovulekile lungaba kokubili Olwe-Object-Oriented kanye ne-prozedural. Izinhlelo ze-PHP ezigxile entweni zithandwa kakhulu phakathi kwamabhizinisi amakhulu kanye ne-codebibliotheken. PHP 5 ilungisa amaphutha ezinguqulweni ezedlule futhi yethula Imodeli Yento efakwe ngokugcwele.

Okuguquguqukayo kuyingxenye emaphakathi ye-PHP. Okuguquguqukayo iqoqo lamanani amelela uhlobo oluthile lwedatha. Ku-PHP, okuguquguqukayo kungamela ububanzi bamanani. Uma inani liwuchungechunge, lokhu okuguquguqukayo kumelela izinhlamvu ezimelelwe yilolu chungechunge. Kungenjalo, inani lingaba yinoma yini. I-PHP isekela ezinye izinhlobo eziningi zokuguquguquka. Lokhu kufaka phakathi ama-arrays nezintambo. Ukusebenzisa lezi, mane nje ufake igama lokuguquguquka ofuna ukukukhohlisa.

phpinfo()

I-phpinfo() umsebenzi ku-PHP ukhombisa ulwazi mayelana ne-PHP. Umhlaseli angasebenzisa lolu lwazi ukuze ahlele ukuhlasela kwakhe. Lolu lwazi luwusizo ekucupheni ukuhlaselwa komjovo we-SQL noma uhla lwemibhalo enqamulayo. Kuya ngokuthi phpinfo() amaphrinti omsebenzi, lolu lwazi lungacekela phansi uhlelo lokusebenza lewebhu. Kwezinye izimo, ingacupha ukuhlaselwa kombhalo wesizindalwazi futhi. Ngokwalesi sizathu, kubalulekile ukuqonda ulwazi lwe-PHP.

I-phpinfo() umsebenzi ubuyisela ulwazi mayelana nemojula ye-PHP. Ulwazi luhlukaniswa ngohlobo lwedatha, okungaba inombolo noma uhlu. Iphrinta idatha njengohlelo, okungase kwenziwe isitayela ukufanisa isayithi. Isikhala sisetshenziswa ngemva kweSistimu ukuhlukanisa idatha. Uma ufuna ukushumeka okukhiphayo komsebenzi, kufanele usebenzise umzimba kanye namathegi e-corpului. Uma ufuna ukushumeka okukhiphayo, kufanele usebenzise i-phpinfo() sebenza njengehange.

php-Interpreter

A PHP interpreter is a tool used to develop websites and applications in the PHP programming language. Umhumushi ufana nozakwenu oyivila osebenza kuphela uma ifayela elikufomethi ye-PHP liceliwe. Icubungula iskripthi futhi ibhale idethi yamanje nesikhathi kudokhumenti ye-HTML, esibe sesilethwa kusiphequluli sewebhu futhi siboniswe. Le nqubo ibizwa ngokuthi “ukunikezwa kwekhasi”.

I-PHP iwumthombo ovulekile we-server-side scripting language. Isetshenziswa emakhasini ewebhu, kanye nasezinhlelweni eziningi ze-CMS. Izimpande zawo zisolimini C, futhi imisebenzi eminingi ejwayelekile isuselwa kulolu limi. Umhumushi we-PHP iyithuluzi elisetshenziselwa ukucubungula ikhodi ye-PHP, futhi itholakala cishe kuzo zonke izinhlelo zokusebenza namapulatifomu. Umhumushi we-PHP ngokuvamile uyinguqulo ehunyushiwe yekhodi ye-PHP.

PHP logische Operatoren

Logic operators are used to combine multiple comparisons. Ngokwesibonelo, opharetha we-UND uxhuma izimo ezimbili, eyokuqala kufanele ibe yiqiniso. KANYE (okuphambene nokuphika) ichaza ukungabikho okunengqondo komsebenzisi. I-PHP futhi isekela opharetha abathathu abengeziwe, okuholela engqikithini yamathuba ayisishiyagalombili anemibi. Ama-opharetha anengqondo asetshenziswa kakhulu uma, ngenkathi, futhi ngenkathi.

Ku-PHP, opharetha babizwa nangokuthi izihlonzi. Lezi ziqhathanisa izinhlobo ezimbili zedatha, futhi uma zingafani, zicutshungulwa ngokulandelana kwazo. I-PHP isebenzisa izihlonzi zokuqhathanisa opharetha ukudwebela amaphutha. Ukuze ubonise imilayezo yephutha, sebenzisa i-global variable $php_errormsg. I-PHP ayihlukanisi phakathi kwama-associative kanye nama-vector array, nakuba zingamelwa ngezintambo nezinombolo. I-PHP isekela opharetha njengokuthi uma (okunye) izitatimende, for-loops, shintsha, futhi uma-isinqumo.

php-Dateien

PHP-Dateien are scripts that allow for web development. Angafinyelelwa futhi asetshenziselwe izinjongo ezihlukahlukene. I-PHP ihlanganisa isistimu yosizo evumela onjiniyela ukuxazulula izimo ezibucayi. Amafayela afana nama-kartons futhi agcinwa kufayela elithi a.php. Uma ifayela lingenawo amathegi afanele, ngeke ibonwe yi-PHP-Parser futhi ngeke isetshenziswe. Kungenjalo, Amafayela e-PHP angadalwa kusetshenziswa umhleli.

I-PHP-Dateien iqukethe i-PHP-Quellcode futhi ingashumeka ku-HTML-Code ukuze kuthuthukiswe iwebhusayithi.. I-PHP ubuchwepheshe bokudala iwebhusayithi obudumile obusebenzisa ulimi lokubhala oluseceleni kweseva. Umsingathi wewebhu uzofaka i-PHP kuseva yayo ukuze ikuvumele ukuthi usebenzise yonke imisebenzi yayo. Ngaphezu kwefayela le-PHP, uzodinga umhleli kanye neklayenti le-FTP ukuze ulayishe amakhasi kuwebhusayithi yakho. Ukuze uqalise, kufanele usebenzise umhlinzeki wokubamba ohloniphekile kanye neklayenti le-FTP. Kunemithetho emithathu eyisisekelo yokuhlela yamafayela we-PHP:

PHP-Programmierer

A PHP Programmierer is a software developer who specialises in creating dynamic web applications. Umhleli we-PHP usebenza ngokubambisana nochwepheshe abavela emikhakheni eyahlukene ukuze bakhe okuqukethwe okunamandla kumawebhusayithi. Iqhaza labo liyahlukahluka futhi lilokhu lishintsha njalo. Lokhu kusho ukuthi imisebenzi ye-PHP Programmer ishintsha njalo futhi iyathuthuka. Kunamathuba amaningi atholakalayo ukuze umklami we-PHP asebenze njenge-freelancer, isisebenzi, noma usonkontileka. Nansi eminye yemisebenzi esemqoka yomhleli we-PHP.

I-PHP Programmierer ingasebenza ngemuva noma ngokuqondile namakhasimende nezinhlelo zawo. Endabeni yokugcina, kungase kudingeke ukuthi bathathe ukuqeqeshwa ukuze babe uMhleli we-PHP. Nokho, ukufunda ngokwenza kudla isikhathi futhi kuvame ukuba namaphutha. Abaningi be-PHP Programmierers basebenza njengama-freelancers futhi bazibekele amanani namahora abo. Njengomhleli we-PHP, ungasebenza ngenani lobuchwepheshe obuhlukahlukene, kusuka kusizindalwazi kuya kumaseva ewebhu kuya ezinhlelweni zokusebenza ze-inthanethi. Ukuze uqale umsebenzi wakho kulo mkhakha, kubalulekile ukufunda izisekelo zokuklama isofthiwe kanye ne-PHP-Frameworks nemitapo yolwazi.

PHP-Standards

The PHP-Standards for programming are designed to make the language easy to use by anyone who wants to write scripts in PHP. Zihambisana nabo bonke abathuthukisi be-PHP futhi azigxili ezimpini ezingcwele ze-whitespace. Njengoba uzobona, into ebaluleke kakhulu okufanele uyikhumbule ukuthi kufanele usebenzise usonhlamvukazi njalo kuma-constants ekilasi, futhi akumele usebenzise unobumba abancane kumagama aguquguqukayo. Kukhona nezinye izindinganiso okufanele unamathele kuzo lapho ubhala ikhodi ye-PHP, futhi lokhu kufaka phakathi ukuqamba amagama okuguquguqukayo nama-constants kokuthi ‘UPPER-CASE’ noma ‘LOWER_CASE’.

I-PHP-Standards yezinhlelo zenzelwe ukunciphisa ukungqubuzana kwengqondo lapho iskena ikhodi yohlelo.. Ukwenza lokhu, bachaza isethi yezinto ezilindelwe okwabelwana ngazo kanye nemithetho mayelana nekhodi yokufometha. Le mithetho isuselwa ezintweni ezifanayo phakathi kwamaphrojekthi angamalungu. Ngokwabelana ngemihlahlandlela yesitayela phakathi kwamaphrojekthi, kusiza kokubili abathuthukisi nabahleli. Lokhu kuwusizo ikakhulukazi uma usebenza namakhodi ahlukene. I-PHP-Standards yokuhlela ayindlela enhle yokugwema ukudideka nokubhala amakhodi okubi.

PHP-Projekte

In PHP programming, okuguquguqukayo kusetshenziselwa ukugcina nokukhohlisa idatha. Okuguquguqukayo kuyizinhlobo ezimbili: izinto namakilasi. Into ingumqondo obonakalayo onezici ezithile, ezifana shape, usayizi, bese uthayipha. Kungokufanayo namakilasi, equkethe ulwazi olufana negama lomsebenzisi. I-PHP isebenzisa izinto ukuhlukanisa idatha, okwenza kube lula ukuhlela kabusha ikhodi. Okulandelayo ezinye zezinhlobo zezinto ezitholakala ku-PHP.

Incazelo yomsebenzi kanjiniyela we-PHP ihlukahlukene. Le misebenzi iyahlukahluka kuye ngobungcweti babo bokuhlela. Bangase basebenze ezinhlelweni zokusebenza zewebhu noma amawebhusayithi futhi balungise ikhodi. Le misebenzi ingaba ngokuzimela noma idinga ukusebenzisana nochwepheshe beminye imikhakha. Ngenkathi iningi lalezi zikhundla zezinhlelo ze-PHP zikhokhelwa, eziningi zizimele futhi zibandakanya ukusebenza nochwepheshe beminye imikhakha. Amakhono ambalwa wokuhlela we-PHP ayadingeka ukuze uphumelele kule ndlela yomsebenzi. Ngakho, uma ufuna umsebenzi onomvuzo, ungabe usabheka!
