PHP: kungxenye yokugcina. An eziningi Dynamics

PHP - liyathembisa futhi yesimanje: a-syntax qualitative engasho lutho ikhono ukwenza kwalokho kuvunyelwe. Ukuqala kokusetshenziswa the imibono lwezinhlelo into-ngamakhasimende kanye nenkululeko zokushintsha uhlobo variable owenza ngokoqobo asemini kwakwakhiwa kakhulu.

Afanayo - ngemiklamo yasendulo, futhi associative - isikhathi intela, kunokuba kuyimfuneko umkhuba. Nakuba zikhona inombolo ezanele imisebenzi ehilela ukudalwa idatha lisinikeza ongakayisebenzisi okuqukethwe (ubuningi, ukubaluleka, izinhlobo namakhodi) enikeziwe, olutholakalayo elokubuka zisebenzisa ngemijikelezo PHP foreach. I element lokugcina afanayo iyatholakala iyiphi indlela indalo. Array - the associative evamile futhi - ukuba ukwazi ukudala uhlu, kodwa i-syntax evamile, PHP awasetshenziswa.

Inani lamanje le-afanayo

Uma ungazinaki Inkomba nokusetshenziswa design

$ ArData [] = scField entsha (); // scNumber, scString, scParagraph, ...

lapho scField () - Umakhi into abstract - "izicucu zolwazi", esesikhundleni, izindlalifa zikaNkulunkulu, inombolo (scNumber), string (scString), imishwana (scParagraph), ... ukuze uthole PHP: kungxenye yokugcina = afanayo ezinto bembonisa impahla yayo njengendlela element langempela.

Ngokuyisisekelo, kungakhathaliseki ukuthi isici ezifanele, kodwa kulokhu kubalulekile ukulandela pointer (e PHP - isikhombisi) ngaphakathi afanayo. Ngokuvamile - kudingeka babe bebodwa cell pointer. Yisimo in a PHP isikhombisi sintula umqondo "engxenyeni yokugcina = afanayo". Iyatholakala ekupheleni umsebenzi () futhi array_pop (), kungxenye yokugcina uyisihambeli sezindawo afanayo. Ukusebenzisa array_pop (), ngaphezu, ngokuzenzakalelayo sekuqalile owedlule afanayo isici futhi izakhiwo zalo Ushintshe ngokufanele. Loku kubangelwa ukuthi kungenzeka ukunyakazisa izakhi.

Ngakho, sicabanga esimeningcondvo PHP-syntax, susa kungxenye yokugcina kumalungu afanayo empeleni kusho ukusebenzisa izakhiwo zalo. izakhi ngokulandelana ukubeka nokususa, sithola izindawo ashukumisayo, ashukumisayo entsha idatha isakhiwo, kwakheka ngaphakathi-syntax etholakalayo.

Umsuka nezinye izakhi

It has a function ukusebenza element lokuqala elifanayo bese ukuhambisa isikhombi yangaphakathi. Ngo-syntax evamile nokobana umkhuba zakudala lwezinhlelo, zingabantu osebenzayo. Ngokuphathelene ukudala afanayo nge ngamandla kokushintsha umqondo - akukho.

Ngo izinhlelo, ngaso sonke isikhathi umbuzo izinqumo: eziguquguqukayo izimo opharetha ukushintsha inkambo algorithm, loops okuthile ahlaziye, imiphumela ekugcineni aveze.

Uma uhambisa maphakathi gravity entweni uqobo nimnike wakhe siqu ngezinqumo azenza, uhlelo livele ngendlela ehluke ngokuphelele, ukubukeka okunenjongo. Ngokuvamile kuba le ndlela ivumela ukufeza umgomo, ikakhulukazi uma kuziwa, isibonelo, ukusetshenziswa amaningi idokhumenti tags * .docx olotshwe ejwayelekile Vula XML.

Ngo PHP ukuze uthole kungxenye yokugcina kumalungu afanayo - ke incazelo entsha futhi ithuba elihle.

amafayela Ukulanda futhi izakhiwo ashukumisayo amaqoqo

Lapho isayithi linikeza ikhono ukulanda yimuphi amafayela, kulula ukusebenzisa umqondo bento abstract, isibonelo, SCFile nenzalo kusuka kuye scImage, scDocument, scTabe, okuzodingeka okufanayo negama izakhiwo, kodwa ehlukene ukubukeka nencazelo yawo (okuqukethwe). Esimeni semakhaya syntax PHP (zinyanga isici = afanayo), usebenzisa ukuphela () umsebenzi, ungakwazi ukuyisebenzisa ngendlela inquma kungxenye yokugcina. Lesi sinqumo ethakazelisayo ukuthi kushintsha isethulo evamile futhi likuvumela uzulazule isakhiwo idatha njengoba labunjwa.

Ukusetshenziswa okunjalo afanayo kubanika incazelo entsha ngokuphelele. Linikeza PHP miyalelo, kodwa ukusetshenziswa okunjalo inikeza amathuba amahle kakhulu.

Ukunikeza imaging, isitoreji database, ukusimama zisesimweni yokusebenza (isibonelo) sizokwazi ukungacabangi ukuthi benzeni endabeni ethile. Wonke amafayela ulayishe ezibekwe kule ngokulandelana afanayo, futhi uma kusetshenzwe, njalo ngokuthi izindlela okufanayo scheme efanayo, kodwa ifayela yesithombe ziyobonakala njengoba injalo, ifayela-spreadsheet - njengoba itafula, kantsi umculu - nombhalo ohambelanayo. Iyatholakala ngokusebenzisa i-syntax PHP timphawu lokugcina afanayo is kuhlomisa izakhiwo zayo futhi okuqukethwe.

Kulo mBhalo, idokhumenti njalo izinhlamvu, strings, izinombolo, futhi, okubaluleke kakhulu, ukufometha. Gcina umbhalo walokho element ngayinye kunzima, kodwa ngokunikela into efanele ngayinye format isici ingatholakala, ngaphandle kokunqikaza, idokhumenti njengoba sinjalo.

Isitaki futhi recursion ngaphakathi le-syntax

Lapho sisebenza kuphela kungxenye yokugcina, isimo main - isitaki, kodwa uma le nto uyabulawa, futhi lisebenzisa ezakheke ngendlela efanayo, futhi ikakhulukazi yena - kuyinto recursion. Singasho sithi izinto eziningi ezinhle mayelana imitapo PHPOffice, PHPWord ezinjalo, kodwa wagomela ukuthi bayaqaphela indlela agcwele ukuthi uhumusha ukufometha koqobo le dokhumenti ku yalokho, awukwazi.

Ngempela, usebenzisa PHPOffice \ PHPWord kungaba ke kalula uvule noma yiluphi Document vordovsky (* .docx), kodwa kuphela ukulondoloza amaningi ehlelekile xml-amafayela, izithombe, kanye nezinye izinto.

Ngesikhathi esifanayo, uma sithatha kuphela xml-amafayela, nakuba zihlobene (ngokuya izitayela, amathebula, izithombe), ngeke zisebenze ukwakha idokhumenti entsha esekelwe ubudala futhi nje wathutha yezinguquko yakhe oyifunayo (isibonelo, ukushintsha umbala wefonti, format). Izinketho ukufaka amathegi Vula-XML isethi, ngisho umkhiqizo ngakho esungulwe efana MS Word, ngaso sonke isikhathi sibhekane ngokuphumelelayo imibono yomsebenzisi, siyawenza amaphutha.

Empeleni * ifayela .docx - zip-archive, futhi isakhiwo ecacile neqondakalayo. Ukusebenzisa inani elincani lezinto kungenziwa ngokusemthethweni wazichaza bese ngesikhathi ufunda, ezimele isakhiwo egcwele idatha, okuyinto zingalawulwa wokufihla.

Kulokhu, ulwazi idokhumenti - esingokomthetho isakhiwo idatha. Ukunika ke umkhuba, ungakwazi kalula uthuthe ezingeni okubaluleke indiva syntax.
