PHP: element ee la soo dhaafay. diyaariyeen ah ee dhaqdhaqaaqa

PHP - waa rajo iyo casriga ah: Saan a tayo iyo kelmedo ee awood u leh inay sameeyaan wixii ka dambeeya waxa loo ogol yahay. Hirgelinta fikradaha barnaamijyada wax-oriented iyo xorriyadda beddelo nooca variable sameeyo xaqiiqada dhabta ah ee duni ugu dhiirato.

Arrays - design qadiimiga ah, iyo laba israacinayo - mar baad ah, halkii shuruud ka mid ah dhaqanka. Inkastoo ay jiraan tiro ku filan oo hawlaha ku lug leh abuurista xogta dhigaya hore aan la bixin content (tiro, qiimaha, noocyada iyo codes), kuwaas oo la heli karo la daawado iyo sida loo isticmaalo ee wareegyada foreach PHP. element ugu danbeysay ee soo diyaariyeen waa mid diyaar u ah hab wax ka mid ah abuurka. Array - israacinayo caadiga ah iyo - oggolaadaan in aad sameysato liiska, laakiin Saan caadiga ah, PHP waa isticmaalka xadidan.

qiimaha hadda ah isu safi

Haddii aad iska indha design index iyo isticmaalka

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

halkaas oo scField () - Constructor wax aan la taaban karin - "gogo 'oo macluumaadka", taas oo uu leeyahay dhaxla, tirada (scNumber), string (scString), weedho (scParagraph), ... si aad u hesho PHP ah: element la soo dhaafay = isugu soo shayada soo bandhigista hantida sida a element dhabta ah.

Muhiimad ahaan, iyadoo aan loo eegayn waxa element tixgeliyo ee khuseeya, laakiin ay dhacdo in this waxaa lagama maarmaan ah in la raaco tilmaamaha (in PHP - dulqabo) gudahood isugu diyaariyeen ka. More inta badan - waxay u baahan yihiin in ay leeyihiin tilmaamaha gacanta u gaar ah. Lagama maarmaan in PHP dulqabo a lahayn fikradda ah "element la soo dhaafay = soo diyaariyeen". Laga heli karaa dhamaadka shaqada () iyo array_pop (), element ee la soo dhaafay sida ergeyga ah in guryaha oo isdiyaarin kara. Isticmaalka array_pop (), marka lagu daro, si toos ah badalato in element la dagaallamaan hore iyo hantida waxaa sida dib u habaynta. Tani waxaa sababa suurtagalnimada ee dhaqdhaqaaqa canaasiirta.

Sayidka, ka fiirsaneysa in macnaha guud ee Saan PHP, ka saar element la soo dhaafay soo diyaariyeen dhab ahaan ka dhigan tahay in la isticmaalo hantida. Sequentially gelinayn oo ay ka saareen xubno ka, waxaan u hesho guryaha firfircoon, cusub firfircoon dhismeedka data, aasaasay gudahood Saan la heli karo.

Asal iyo xubno kale

Waxay leedahay shaqo si ay ula element ugu horeysay ee isugu soo shaqeeyaan oo guurto pointer gudaha. In Saan caadi ah in fulisaa dhaqanka classic of barnaamijyada, iyagu waa lagu dabaqi karo. Iyadoo la tixgelinayo in la abuuro Arrays la dynamically beddelo dareen - no.

In barnaamijyada, waxaa had iyo jeer waa su'aal of go'aan-qaadasho: doorsoomayaasha yihiin shuruudaha shaqaale si loo bedelo koorsada geynta ah, siddo wax falanqaynta, natiijooyinka ugu danbeyn soo saaray.

Haddii aad xarunta of cuf dhaqaaqo shay dhabta ah iyo isaga siin go'aanada isaga u gaar ah, barnaamijka qaadataa on gebi ahaan kala duwan, eegtid oo ah macno leh. Inta badan waa habka tani waxay u oggolaanaysaa in la gaaro goolka, gaar ahaan marka ay timaado, tusaale ahaan, isticmaalka tags document badan * Buug gacmeedka, diiwaan geliyay XML caadiga Open.

In PHP si aad u hesho element la soo dhaafay soo diyaariyeen - waa macnaha cusub oo fursad fiican.

Degsado files iyo guryaha firfircoon of Arrays

Marka goobta bixisaa awood u leh inay kala soo bixi wax kasta oo files, waxaa habboon in la isticmaalo fikradda ah shay la taaban karin, tusaale ahaan, SCFile iyo Faracoodii isaga ka scImage, scDocument, scTabe, oo waxay yeelan doonaan guryaha magac la mid ah, laakiin kala duwan oo ay muuqaalka iyo macnaha (content). Macnaha ku jira Saan PHP ah (element ugu danbeysay = safi), iyadoo la isticmaalayo dhamaadka function (), waxaad u isticmaali kartaa sida ay u go'aamiso element ee la soo dhaafay. Go'aankan waxaa ku xiiseynayaan in ay dumiso bandhigidda caadiga ah oo kuu ogolaanaya in aad maraan dhismeedka xogta sidii lagu sameeyay.

isticmaalka noocan ah ee Arrays iyaga macne cusub siinayaa. Waxay bixisaa Saan PHP, laakiin isticmaalka noocan ah waxay bixiyaan fursado weyn.

Bixinta imaging, kaydinta in database ah, soo kabashada in xaaladiisu (tusaale ahaan) waxa ay noqon doontaa suurto gal ma aha in aad ka fikirto waxa la sameeyo haddii ay dhacdo gaar ah. All files uploaded waxaa la geeyaa sequentially oo isdiyaarin kara, oo marka la farsameeyo, waxaa had iyo jeer loo yaqaan habab isku mid ah nidaamka isku, laakiin file image ee lagu soo bandhigi doonaa sida uu yahay, faylka isbiriidhshiit - sida miis, iyo dokumentiga - text u dhigma. Laga heli karaa Saan PHP ee element ugu dambeeyey ee soo diyaariyeen ah waa qalabaynta hantida gaarka ah iyo content gaar ah.

Xaalada danbe, dokumentiga had iyo jeer waa characters, xadhig, lambarada, iyo, ugu muhiimsan, formatting. La soco element kasta waa ay adag tahay, laakiin by siinta wax ku habboon ee element format kasta waxaa laga heli karaa, oo aan libiqsanayn, dokumentiga sida ay tahay.

Dhoobo iyo Recursion gudahood Saan

Marka waxaan ka shaqaynaynaa oo keliya element ee la soo dhaafay, xaaladda ugu weyn - xidhmooyin, laakiin markii this item waxaa qaybshay, oo wuxuu u adeegsanayaa dhismaha la mid ah, iyo gaar ahaan qudhiisu - waa recursion. Waxaan dhihi karnaa waxyaabo badan oo wanaagsan oo ku saabsan maktabadaha PHPOffice, sida PHPWord, laakiin ku dooday in ay ogaadaan hab buuxa in tarjumayaa formatting asalka ah ee dokumentiga in natiijada aad, Ma yeeli karno.

Indeed, iyadoo la isticmaalayo PHPOffice \ PHPWord ka dibna si fudud u noqon furan kartaa Document vordovsky kasta (* Buug gacmeedka), laakiin waxaa la archive kaliya badan habeysan XML-files, sawiro, iyo waxyaabaha kale.

Isla mar ahaantaana, haddii aan qaadan oo keliya XML-files, inkastoo ay la xiriira (marka la eego Hababka, miisaska, sawirada), ma shaqayn doonaa si ay u sameeyaan dukumenti cusub oo ku salaysan jir ah oo kaliya u dhaqaaqay isbedel uu doonayo (tusaale ahaan, ka beddeli midabka font ee, format). Options si aad u dalbato tags XML set Open, iyo xitaa wax soo saarka si-la aasaasay sida MS Word, ma had iyo jeer la qabsadaan fikradaha user ee, qaladaad samayso.

Dhab ahaantii * file - Buug gacmeedka ah zip-archive, iyo qaab-dhismeedka cad oo la fahmi karo. Isticmaalka tiro yar oo alaab ah si rasmi ah u tilmaamay kartaa oo aad hesho waqti ah akhriska, qaab-dhismeedka buuxda oo madax banaan xogta, taas oo semantically la kaantarooli karaa.

Xaaladdan oo kale, macluumaadka dukumintiga - dhismeedka data rasmi ah. waxaa Siinta isbedel ah, waxaad si fudud u haajiraan kartaa heerka macnaha iyo iska indha Saan ah.
