Ngilungisa kanjani izinhlaka?

Ngokuvamile uma uxazulula imisebenzi ethile, kuyadingeka ukuhlunga idatha egcinwe ohlwini. Kuyini ukuhlelwa kwezinto zokubala? Lapha, ngokwesibonelo, ukudlala okuthandayo, abantu babeka amakhadi abo ngenani futhi lihambisana. Lokhu kwenza kube lula ukunquma ukuthi yiziphi ezinye amakhadi abakwaziyo. Futhi kuzo zonke izichazamazwi konke kuhlelwa nge-alfabhethi. Kunezibonelo eziningi. Ukuhlunga ukulungiswa kwesethi ethile yezinto ngenye indlela ngokusho kwesici esichaziwe. Ukuhlelwa kwe-arrays kuyadingeka kaningi. Ngenxa yalokhu, kusetshenziswe izindlela ezahlukene. Ukuze uqonde lokho okusemqoka, kwanele ukucabangela ngokuningiliziwe izindlela eziningana.

Ngokusekelwe kulokho abakwenzayo

Kubalulekile ukuqonda ukuthi i-array inezinhlobo eziningi zezikhiye namanani athile. Ukuhlelwa kwezingxenye zolimi lwe-C kwenziwa ngosizo lwemigqa eminingi yekhodi, futhi ku-PHP lokhu kutholakala kuphela ngomyalo owodwa olula. I-Arrays ingahle ihlelwe ngokususelwa kumakhi noma amanani. Usengakwazi ukusabalalisa amanani, uwashiye izikhiye ezikhona noma ubeke amasha.

Ukuhlukana komsebenzi omkhulu

Ukuhlunga kohlelo lwe-PHP kunokwenzeka ngokusebenzisa imisebenzi ehlukahlukene. Ake sibheke ukuthi bahluke kanjani:

- Ezinye imisebenzi zihlunga izigaba ngezihluthulelo zezakhi zawo, kanti ezinye ngamanani.

- Kukhona uhlobo oluhlukile lohlobo: ukwehla, ukukhula, kwemvelo, izinombolo, uhlamvu lwama-alfabhethi, okuchazwe ngumsebenzisi noma okungahleliwe.

- Ezinye imisebenzi ziyakwazi ukusindisa ngemuva kokuhlunga uxhumano olukhona phakathi kwesihluthulelo nenani. Kodwa kunemisebenzi lapho okhiye behlelwa kabusha kumanani amasha.

- Umsebenzi ngamunye uguqula uhlu oludlulisiwe. Ababuyiseli ikhophi ehlelwe.

- Ukuhleleka okunjalo kubhekwa kungacacisiwe lapho umsebenzi uchaza izakhi ezimbili njengelilinganayo. Lona uhlobo oluzinzile.

Eminye imisebenzi yokuhlunga ama-arrays ku-PHP

Imisebenzi () kanye ne-rsort () . Hlunga () uhlela uhlu ku-alfabhethi. Qaphela ukuthi lo msebenzi uyinkinga ebucayi. Ukuhlunga ngamagugu ngaphandle kokhiye okwenzekayo. I-Rort () ibeka amanani ngokuhleleka okulandelanayo, futhi ayicabangi ngezihluthulelo.

I-Asort () ingenye yemisebenzi egcina ubuhlobo bamakhi kanye namagugu. Kuwusizo ukusebenzisa izigaba zokuxhumana, uma lokhu kubalulekile.

Esikhathini, izihluthulelo zingamagama ezithelo, futhi amanani amanani. Ukuhlunga kwenzeka ukwehla kwentengo. Uma ukuhlunga ngamagama ezithelo kuyadingeka , khona-ke umsebenzi ksort (), ohamba ngezinkinobho , udinga. I-Arsort () ihlela izigaba eziyisithupha ezihambisana nezinkomba (ezichazayo) ngokuhlehlisa. I-Krsort () ihambisa izihluthulelo zezinto ezihlahleni.

I-pair-dimensional array

Kuyathakazelisa ukuhlunga uhlangothi lwamabili. Lokhu kungenziwa ngezindlela ezahlukene. Ku-PHP, kungenzeka uqhathanise izinombolo ezimbili noma imigqa emibili. Kodwa kunoma yiluphi uhlu oluhlukahlukene, zonke izakhi ziyingxenye. Ku-PHP, ukuqhathanisa izingxenye eziningana, udinga ukwakha indlela ethile. Cabanga ngamagama amabili-ntathu lapho igama elifingqiwe lesithelo, igama eligcwele kanye nentengo ligcinwa. Izinto ze-array zingalungiswa ngama-alfabhethi ngamagama abhaliwe.

Esikhathini, umsebenzi wethu unegama eliqhathaniswa (qhathanisa). Unamaphuzu amabili - x, y. Umsebenzi kumele uthathe amanani angu-2, bese unquma ukuhleleka. Imingcele x, yilezi zigaba ezimbili eziphakathi kwendawo. Ukuqhathanisa incazelo-izakhi ezivela emidlalweni edluliselwe emsebenzini, okuguquguqukayo $ x [1], $ y [1] kuyadingeka. Umzila we-return1 ubuyisela inani kukhodi ebizwa ngokuthi umsebenzi. Ukuhlelwa kwesigaba sethu kusekelwe ekusebenziseni (). Ukuhlunga kulandela imithetho eqhathaniswayo () umsebenzi echaza.

Manje ukuhlunga izingxenye ku-PHP kuzoqondakala kuwe.
