PHP: ikpeazụ mmewere. Otu n'usoro nke Ọnọdụ

PHP - bụ ekwe na oge a: a qualitative syntax na semantics nke nwere ike ime ihe karịrị ihe ka. Mmejuputa iwu-nke echiche nke ihe na-abara mmemme na nnwere onwe nke na-agbanwe agbanwe ụdị nke agbanwe ka eziokwu nke kasị daring fantasies.

Arrays - ochie imewe, na associative - a ụtụ oge, kama a chọrọ omume. Ọ bụ ezie na e nwere ndị a zuru ezu ọnụ ọgụgụ nke aga-eme na-agụnye ihe e kere eke nke data tent mbụ nyere ọdịnaya (buru ibu, uru, na ụdị na-codes), nke dị maka ikiri na-eji na cycles PHP foreach. The ikpeazụ mmewere nke n'usoro dị maka ọ bụla usoro e kere eke. Hazienụ - na mbụ associative na - ekwe ka gị ike anatara, ma na-emebu syntax, PHP bụ nke mmachi were.

Ugbu uru nke n'usoro

Ọ bụrụ na ị na-eleghara ihe index na ojiji imewe

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

ebe scField () - Constructor nkịtị ihe - "iberibe ọmụma", nke nwere ndị nketa: nọmba (scNumber), eriri (scString), nkebi ahịrịokwu (scParagraph), ... na-PHP: ikpeazụ mmewere = n'usoro ihe na-egosi ya Njirimara dị ka a n'ezie mmewere.

Nnoo, n'agbanyeghị ihe mmewere atụle mkpa, ma na nke a ọ dị mkpa iji na-eso pointer (na PHP - cursor) n'ime n'usoro. More mgbe - mkpa ka nwere onwe ha cell pointer. Ọ bụ mkpa na a cursor PHP kọrọ echiche nke "ikpeazụ mmewere = n'usoro". Dị site ọrụ njedebe () na array_pop (), na nke ikpeazụ mmewere dị ka onye nnọchiteanya Njirimara n'usoro. Iji array_pop (), ke adianade do, na-akpaghị aka switches ka gara aga n'usoro mmewere na ya Njirimara na-gbanwetụrụ ya. Nke a na-mere site ekwe omume nke ije nke ndị ọcha.

N'ihi ya, na-atụle na onodu nke PHP syntax, wepụ ikpeazụ mmewere ke n'usoro pụtara n'ezie iji ya Njirimara. Sequentially ịtụkwasị na wepụ ọcha, anyị na-enweta ike Njirimara, ọhụrụ ike data Ọdịdị, kpụrụ n'ime dị syntax.

Mmalite na ndị ọzọ ọcha

Ọ nwere ọrụ na-arụ ọrụ na-akpa mmewere nke n'usoro na-akpali esịtidem pointer. Na nkịtị syntax na implements kpochapụwo omume nke mmemme, ha na-na ọdabara. Banyere eke arrays na dynamically agbanwe uche - dịghị.

Na mmemme, ọ bụ mgbe niile a ajụjụ nke mkpebi: variables bụ ọnọdụ ndị ọrụ ịgbanwe N'ezie nke algọridim, anya nko ihe nyochaa, emecha rụpụtara.

Ọ bụrụ na ị na-akpali ndị center mpo ahụ n'ezie ihe na-enye ya, ya onwe ya mkpebi, usoro ihe omume na-ewe ke kpamkpam dị iche iche, nwee nzube anya. Ọtụtụ mgbe, ọ bụ usoro a na-enye ohere iji nweta ihe mgbaru ọsọ, karịsịa mgbe ọ na-abịa, n'ihi na ihe atụ, na ojiji nke multiple akwụkwọ tags * .docx, dere na ọkọlọtọ Open XML.

Na PHP iji nweta ikpeazụ mmewere na n'usoro - ya a ọhụrụ pụtara na a ezi ohere.

Nbudata faịlụ na ike Njirimara nke arrays

Mgbe saịtị awade ike ibudata ọ bụla nke faịlụ, ọ bụ adaba iji echiche nke onye nkịtị ihe, n'ihi na ihe atụ, SCFile na ụmụ ya scImage, scDocument, scTabe, nke ga-enwe otu aha Njirimara, ma dị iche iche ha dị na pụtara (ọdịnaya).
