Phunzirani zoyambira za pulogalamu ya PHP

PHP-Tutorial imayamba ndikuyambitsa kosavuta kwa mapulogalamu mu PHP. It then proceeds to teach you HTML and CSS as well. Mudzakhala panjira yoti mukhale katswiri wamaphunziro. Koma musanayambe, ndikofunikira kudziwa zoyambira zamapulogalamu musanapite kunjira zapamwamba kwambiri. Nawa malangizo oyambira:

Object-Orientierte Programmierung

In Object-Oriented PHP Programmierung, makalasi ndiwo maziko a chinenero cha pulogalamu. Makalasi awa akuyimira mtundu wina wa data. Chinthu chikhoza kukhala chosinthika, ntchito, kapangidwe ka data, kapena mtengo. Popanga kalasi, gawo loyamba la dzina ndi mawu osakira atsopano, ndiyeno dzina la kalasi ndi prefix. Chiyambi ichi chimagwiritsidwa ntchito popanga zinthu zatsopano, zomwe kenako zimasungidwa mumitundu yosiyanasiyana. Chinthu chingakhalenso ndi katundu ndi njira.

OOP ndi njira yosinthiranso dziko kukhala mitundu ingapo yolumikizirana. Mwachitsanzo, mutha kulemba script yomwe imagwiritsa ntchito ntchito kuti mufufuze database kapena kupanga tsamba lawebusayiti. Njira imeneyi imadziwika kuti polymorphism. Zinthu zitha kusinthidwa, kutanthauza kuti code yomweyi ingagwiritsidwe ntchito pazinthu zosiyanasiyana. Pulogalamu ikhoza kupangidwa ndi zinthu zingapo, ndipo chinthu chilichonse chidzakhala ndi ntchito yosiyana.

Typo3

If you’re new to TYPO3 and PHP coding, ndiye muyenera kuwerenga nkhaniyi. Typo3 ndi CMS yovuta yokhala ndi zinthu zambiri, koma zida zochepa. Pulagi yake Directory ndi yaing'ono, poyerekeza ndi WordPress ndi ma CMS ena otchuka. CMS iyi yakhalapo kwa zaka zingapo ndipo yakhalapo kwa zaka zambiri. Komabe, ndikofunikira kumvetsetsa kuti si a “chimango” ngati WordPress, ndipo imafuna kukonzanso kosalekeza kuti zisapitirire ndikugwira ntchito.

Ntchito za TYPO3 CMS zimalembedwa mu PHP. Ma syntax ndi ofanana ndi PHP, ndipo izi zimalola zowonjezera ndi kusinthidwa. Magwiridwe a XCLASS amakulolani kuti mulembe makalasi ndi njira. TypoScript imagwiritsidwanso ntchito pazosintha zam'mbuyo. Mwambiri, imagwiritsa ntchito mawu ofanana ndi TYPO3, koma coding ndi yosiyana pang'ono. TYPO3 imagwiritsa ntchito fayilo yotchedwa TSconfig pazosintha zam'mbuyo ndi zam'mbuyo.

PHP

Learn about PHP and its basics with these tutorials. PHP ndi chiyankhulo chosunthika chomwe chimatha kugwira ntchito pa seva iliyonse yapaintaneti ndipo chingagwiritsidwe ntchito kupanga tsamba lamtundu uliwonse. Chilankhulo cholembera gwero lotsegukachi chikhoza kukhala cholunjika pa chinthu komanso chaukadaulo. Mapulogalamu a PHP omwe ali ndi zolinga ndizodziwika kwambiri pakati pa mabizinesi akuluakulu ndi codebibliotheken. PHP 5 amakonza zolakwika m'matembenuzidwe am'mbuyomu ndikuyambitsa Object Model yowoneka bwino.

Zosintha ndi gawo lapakati la PHP. Kusintha ndi kusonkhanitsa kwazinthu zomwe zimayimira mtundu wina wa deta. Mu PHP, zosintha zimatha kuyimira mitundu yosiyanasiyana. Ngati mtengo ndi chingwe, kusintha uku kumayimira zilembo zomwe zikuimiridwa ndi chingwecho. Apo ayi, mtengo ukhoza kukhala chilichonse. PHP imathandizira mitundu ina yambiri yamitundu yosiyanasiyana. Izi zikuphatikizapo masanjidwe ndi zingwe. Kugwiritsa ntchito izi, ingolowetsani dzina lazosintha zomwe mukufuna kusintha.

phpinfo()

Phpinfo() ntchito mu PHP ikuwonetsa zambiri za PHP. Wowukirayo atha kugwiritsa ntchito chidziwitsochi kukonzekera kuwukira kwawo. Izi ndizothandiza poyambitsa jekeseni wa SQL kapena kuukira kwachikwatu. Kutengera zomwe phpinfo() zisindikizo ntchito, izi zikhoza kuwononga ukonde ntchito. Nthawi zina, ikhoza kuyambitsanso kuwukira kwa scripting. Pachifukwa ichi, ndikofunikira kumvetsetsa zambiri za PHP.

Phpinfo() ntchito imabweretsanso zambiri za PHP module. Zambiri zimagawidwa ndi mtundu wa data, yomwe ikhoza kukhala nambala kapena gulu. Imasindikiza deta ngati gulu, zomwe zitha kulembedwa kuti zigwirizane ndi tsambalo. Danga limagwiritsidwa ntchito pambuyo pa System kulekanitsa deta. Ngati mukufuna embed linanena bungwe ntchito, muyenera kugwiritsa ntchito thupi ndi ma tag corpului. Ngati mukufuna embed linanena bungwe, muyenera kugwiritsa ntchito phpinfo() ntchito ngati nangula.

php-Interpreter

A PHP interpreter is a tool used to develop websites and applications in the PHP programming language. Womasulirayo ali ngati mnzake waulesi yemwe amagwira ntchito pokhapokha ngati fayilo yamtundu wa PHP ikufunsidwa. Imakonza script ndikulemba tsiku ndi nthawi yomwe ilipo mu chikalata cha HTML, zomwe zimaperekedwa kwa msakatuli ndikuwonetsedwa. Njirayi imatchedwa “kumasulira kwatsamba”.

PHP ndi chilankhulo chotseguka cha seva-side scripting. Amagwiritsidwa ntchito pamasamba, komanso m'mapulogalamu ambiri a CMS. Mizu yake ili m'chinenero cha C, ndipo ntchito zambiri zokhazikika zimachokera ku chilankhulo ichi. Womasulira PHP ndi chida chomwe chimagwiritsidwa ntchito pokonza ma code PHP, ndipo likupezeka pafupifupi machitidwe onse opangira ndi nsanja. Womasulira PHP nthawi zambiri amatanthauzira mtundu wa PHP.

PHP logische Operatoren

Logic operators are used to combine multiple comparisons. Mwachitsanzo, woyendetsa UND amalumikiza zinthu ziwiri, choyamba chiyenera kukhala chowona. NDI (motsutsana ndi kukana) imatanthauzira kusakhalapo koyenera kwa woyendetsa. PHP imathandizanso ogwiritsa ntchito ena atatu, kupangitsa kuti pakhale zotheka zisanu ndi zitatu zokhala ndi zoyipa. Ogwiritsa ntchito zomveka omwe amagwiritsidwa ntchito kwambiri ndi ngati, pamene, ndi nthawi.

Mu PHP, ogwira ntchito amatchedwanso zozindikiritsa. Izi zikufanizira mitundu iwiri ya data, ndipo ngati sizili zofanana, amakonzedwa mwadongosolo. PHP imagwiritsa ntchito ofananitsa ozindikiritsa kuti atsindike zolakwika. Kuti muwonetse mauthenga olakwika, gwiritsani ntchito kusintha kwapadziko lonse $php_errormsg. PHP sichisiyanitsa pakati pa ma associative ndi ma vector arrays, ngakhale iwo akhoza kuyimiridwa ndi zingwe ndi manambala. PHP imathandizira ogwiritsa ntchito ngati (zina) mawu, kwa-loops, kusintha, ndi ngati-chisankho.

php-Dateien

PHP-Dateien are scripts that allow for web development. Atha kupezeka ndi kugwiritsidwa ntchito pazifukwa zosiyanasiyana. PHP imaphatikizapo njira yothandizira yomwe imalola opanga kuthetsa zovuta. Mafayilo ndi ofanana ndi ma kartons ndipo amasungidwa mu fayilo ya a.php. Ngati fayilo ilibe ma tag oyenera, sichidzazindikirika ndi PHP-Parser ndipo sichidzachitidwa. Kapena, PHP-mafayilo akhoza kupangidwa pogwiritsa ntchito mkonzi.

PHP-Dateien ili ndi PHP-Quellcode ndipo imatha kuphatikizidwa mu HTML-Code pakupanga tsambalo.. PHP ndiukadaulo wodziwika bwino wopanga tsamba lawebusayiti womwe umagwiritsa ntchito chilankhulo cholembera pa seva. Wothandizira pa intaneti adzayika PHP pa seva yake kuti ikulole kugwiritsa ntchito ntchito zake zonse. Kuwonjezera pa PHP-file, mufunika mkonzi ndi kasitomala wa FTP kuti mukweze masamba patsamba lanu. Kuti tiyambe, muyenera kugwiritsa ntchito wopatsa wodalirika komanso kasitomala wa FTP. Pali malamulo atatu ofunikira opangira mafayilo a PHP:

PHP-Programmierer

A PHP Programmierer is a software developer who specialises in creating dynamic web applications. Wopanga mapulogalamu a PHP amagwira ntchito mogwirizana ndi akatswiri ochokera m'magawo osiyanasiyana kuti apange zinthu zamphamvu pamasamba. Udindo wawo ndi wosiyanasiyana ndipo umasintha nthawi zonse. Izi zikutanthauza kuti ntchito za PHP Programmer zikusintha nthawi zonse ndikusintha. Pali mwayi wambiri wopezeka kuti wopanga mapulogalamu a PHP azigwira ntchito ngati freelancer, wogwira ntchito, kapena kontrakitala. Nazi zina mwazochita zazikulu za pulogalamu ya PHP.

PHP Programmierer amatha kugwira ntchito kumbuyo kapena mwachindunji ndi makasitomala ndi machitidwe awo. Pomaliza, angafunikire kutenga maphunziro kuti akhale PHP Programmierer. Komabe, kuphunzira pakuchita kumatenga nthawi ndipo nthawi zambiri kumakhala kolakwika. Ambiri a PHP Programmierers amagwira ntchito ngati odziyimira pawokha ndikudziyika okha mitengo ndi maola awo. Monga wopanga mapulogalamu a PHP, mukhoza kugwira ntchito zosiyanasiyana zamakono, kuchokera ku databases kupita ku ma webservers kupita ku intaneti. Kuti muyambe ntchito yanu mu gawo ili, ndikofunikira kuphunzira zoyambira zamapulogalamu apulogalamu ndi PHP-Frameworks ndi malaibulale.

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. Amagwirizana ndi onse opanga ma PHP ndipo samayang'ana pa nkhondo zoyera za whitespace. Monga mukuwonera, Chofunikira kwambiri kukumbukira ndikuti nthawi zonse muyenera kugwiritsa ntchito zilembo zazikulu pazosintha zamakalasi, ndipo musagwiritse ntchito zilembo zing'onozing'ono za mayina osiyanasiyana. Palinso miyezo ina yomwe muyenera kutsatira polemba ma PHP code, ndipo izi zikuphatikiza kutchula mayina ndi zosintha mu 'UPPER-CASE’ kapena 'LOWER_CASE'.

Miyezo ya PHP yamapulogalamu amapangidwa kuti achepetse kugundana kwachidziwitso mukasanthula ma code a pulogalamu.. Kuchita izi, amatanthauzira zoyembekeza zogawana ndi malamulo okhudza masanjidwe a code. Malamulowa amachokera kuzinthu zofanana pakati pa ntchito za mamembala. Pogawana malangizo a kalembedwe pakati pa mapulojekiti, zimathandiza onse opanga ndi okonza. Izi ndizothandiza makamaka mukamagwira ntchito ndi ma codebase osiyanasiyana. Ma PHP-Miyezo yamapulogalamu ndi njira yabwino yopewera chisokonezo ndi zolemba zoyipa.

PHP-Projekte

In PHP programming, zosinthika zimagwiritsidwa ntchito kusunga ndikusintha deta. Zosintha zili zamitundu iwiri: zinthu ndi makalasi. Chinthu ndi lingaliro la thupi lomwe lili ndi makhalidwe enaake, monga mawonekedwe, kukula, ndi type. N'chimodzimodzinso ndi makalasi, zomwe zili ndi zambiri monga dzina la wogwiritsa ntchito. PHP imagwiritsa ntchito zinthu kulekanitsa deta, kupanga kukhala kosavuta kuyitanitsanso kachidindo. Zotsatirazi ndi zina mwa mitundu ya zinthu zomwe zimapezeka mu PHP.

Mafotokozedwe a ntchito ya wopanga PHP ndi osiyanasiyana. Ntchito izi zimasiyana malinga ndi luso lawo la mapulogalamu. Atha kugwira ntchito pamawebusayiti kapena mawebusayiti ndikuwongolera ma code. Ntchitozi zitha kukhala zodzichitira paokha kapena zimafuna mgwirizano ndi akatswiri ochokera kumaphunziro ena. Ngakhale ambiri mwa mapulogalamuwa a PHP amalipidwa, ambiri ndi odzichitira pawokha ndipo amaphatikiza kugwira ntchito ndi akatswiri ochokera kumagulu ena. Maluso ochepa a mapulogalamu a PHP ndi ofunikira kuti muchite bwino pantchitoyi. Choncho, ngati mukufuna ntchito yopindulitsa, osayang'ananso kwina!
