PHP: wokupedzisira maatomu akafanana. An siyana emuchina

PHP - iri vaizotibata uye ano: a Qualitative nemarongerwo uye semantics ari kugona kuita zvinopfuura chii anobvumirwa. Implementation pfungwa nechinhu vaifarira zvirongwa uye rusununguko kuchinja zvaimirirwa shanduka unoita chokwadi kupfuura ushingiwo muchimuka.

Arrays - zvakagadzirwa yekare, uye associative - imwe nguva mutero, pane zvinodiwa kudzidzira. Kunyange paine imwe nhamba yakakwana mabasa dzinosanganisira kusikwa date seti kwete kare akapa kugutsikana (uwandu, kukosha, marudzi uye Codes), izvo zvinowanikwa kuti kuona uye akashandisa zvinogara PHP foreach. The wokupedzisira che siyana kuwanikwa chero nzira zvisikwa. Array - zvatinosiita associative uye - vachikubvumira kusika mazita, asi mune dzose nemarongerwo, PHP haanyanyi kushandiswa.

Current kukosha kuko

Kana ukasateerera indekisi uye kushandiswa magadzirirwo

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

apo scField () - Constructor Abstract chinhu - "zvidimbu mashoko", iro rine vadyi venhaka: nhamba (scNumber), tambo (scString), mitsara (scParagraph), ... kuwana PHP: wokupedzisira vanzwe = siyana zvinhu nedzokunze zvivako ayo ari chaidzo eremendi.

Zvikurukuru, pasinei chaikosha vaiona akakodzera, asi muchiitiko chino zvakafanira kutevera Pointer (mu PHP - cursor) mukati siyana. More kazhinji - vanofanira kuva avo muchitokisi Pointer. Faniro ari cursor PHP haana pfungwa "wokupedzisira chinhu = kuko". Available kuburikidza mashandiro kuguma () uye array_pop (), wokupedzisira chinhu senhume Zvivako hondo. Kushandisa array_pop (), mukuwedzera, kwaita Minamato haipindurwe kuti rapfuura mumitsetse chinhu uye zvivako dzayo dzakachinjwa maererano. Izvi anokonzerwa mukana kwebasa okunze.

Saka, tichifunga ari akapoteredza PHP nemarongerwo, bvisa rokupedzisira chinhu siyana chaizvoizvo zvinoreva kushandisa zvivako ayo. Sequentially vakagovera nokubvisa okunze, tinowana simba ehupfumi, idzva simba date mamiriro, yakaumbwa mukati iripo nemarongerwo.

Origin nezvimwe zvinhu

It ane basa kushanda wokutanga che siyana uye kufambisa zvemukati Pointer. Chaiye nemarongerwo kuti zvokurimisa mashoko chaiwo tsika mapurogiramu, ivo zvinoshanda. Panyaya asika arrays pamwe dynamically kuchinja pfungwa - kwete.

In mapurogiramu, nguva dzose mubvunzo kuti sarudzo: variables ndiwo mamiriro ezvinhu ari opareta kushandura weboka algorithm, zvishwe chinhu ongorora, pakupedzisira nemigumisiro.

Kana kufamba pakati negiravhiti chaiko chinhu uye kumupa zvisarudzo zvake, chirongwa anobva zvakasiyana zvachose, zvinovaka kutarira. Kakawanda iri nzira iyi kunoita kuti awane chinangwa, kunyanya kana toreva Somuenzaniso, kushandiswa vakawanda gwaro Tags * .docx, chakanyorwa tichienzanisa Open XML.

In PHP kuwana rokupedzisira chinhu siyana - kuripa revo itsva uye mukana wakanaka.

Kudhanilodha mafaira uye simba zvivako zviri arrays

Kana nzvimbo anoda anokwanisa kukopa chero mafaira, zviri nyore kushandisa pfungwa husingaoneki chinhu Somuenzaniso, SCFile uye nezvizvarwa kwaari scImage, scDocument, scTabe, izvo zvakafanana zita ehupfumi, asi zvakasiyana chitarisiko uye zvinoreva yavo (kugutsikana). Munguva yacho PHP nemarongerwo (wokupedzisira chinhu = kuko), achishandisa magumo () basa, unogona kuishandisa nenzira kwayo kunotema rokupedzisira maatomu akafanana. Chisarudzo ichi Zvinofadza pakuti kudzokera zvatinosiita mharidzo uye anobvumira kuti tikunde date mamiriro sezvo yakaumbwa.

kushandiswa rwakadaro arrays zvinovapa zvazvinoreva zvachose itsva. Inopa PHP nemarongerwo, asi kushandisa kwakadaro kunopa mikana zvikuru.

Kupa kuri, kuchengetwa ari Database, yavaipora iri uchishandisa ezvinhu (semuenzaniso) ichava zvichibvira arege kufunga zvokuita imwe nyaya. All uploaded mafaira inoiswa siyana sequentially, uye kana kupatsanurwa, nguva dzose inonzi chete nzira nokuda chete zano, asi mufananidzo faira chichange uratidzwe sezvo ndiro spreadsheet faira - sezvo tafura, uye gwaro - iri runoenzanirana rugwaro. Available kuburikidza PHP nemarongerwo rokupedzisira che siyana ari yokusimbisa pachake zvivako ayo uye yakananga kugutsikana.

Mukupera nyaya, gwaro iri nguva dzose vatambi, hungiso, nhamba, uye, Chikurukuru, formatting. Ramba uchiongorora nechimwe chinhu chakaoma, asi kupa zvakakodzera chinhu chimwe pamanyorerwo chaikosha kunogona kuwanikwa, pasina kumbozengurira, gwaro sezvazviri.

Stack uye Recursion mukati nemarongerwo

Kana tiri kushanda chete rokupedzisira maatomu akafanana, huru mamiriro - murwi wemagazini, asi kana chinhu uyu aurayiwa, uye anoshandisa chete pakuvaka, uye kunyanya pachake - ndiko recursion. Tinogona kutaura zvakawanda zvakanaka pamusoro mumaraibhurari PHPOffice, zvakadai PHPWord, asi vakati kuti vanoziva dzakazara mashandiro kuti anoshandurwa pakutanga formatting iri gwaro iri mugumisiro, haukwanise.

Zvechokwadi, achishandisa PHPOffice \ PHPWord anogona zvino kuzarura kuva nyore chero vordovsky Document (* .docx), asi chete Archive akawanda muronga XML-mafaira, mifananidzo, uye zvimwe zvinhu.

Panguva iyoyowo, kana tikatora chete XML-mafaira, kunyange zvazvo vari ukama (nemashoko siyana, matafura, mifananidzo), hakushandi kuumba gwaro idzva kwakavakirwa akwegura uye chete vakatamira vaida kuchinja ake (somuenzaniso, kushandura Sarudza ruvara, urongwa). Options kushandisa Tags Open XML yakatarwa, uye kunyange zvakadaro-hwakasimbiswa chigadzirwa kufanana MS Shoko, kwete nguva dzose kukunda rokushandisa pfungwa, vanokanganisa.

Chaizvoizvo * .docx faira - zip-Archive, uye yakajeka uye unonzwisisika marongerwo. Kushandisa vashoma zvinhu zvinogona pamutemo kurondedzerwa uye kuwana panguva kuverenga zvizere, yakazvimirira mashoko mamiriro, izvo zvinogona kudzorwa semantically.

Panyaya iyi, mashoko ari gwaro - wevakadzidza date mamiriro. Kupa izvozvo kuitika, munogona tama nyore kusvika padanho zvinoreva uye kuteerera nemarongerwo.
