I yokuhluza njani ma?

Amaxesha amaninzi xa usombulula imisebenzi ethile efunekayo ukwenza ukuhlela data lugcinwe uluhlu. Yintoni ukuhlela ma? Apha, umzekelo, idlala cards, abantu babeka amakhadi zabo phezu ixabiso isuti. Oku kwenza kube lula ukufumanisa ukuba ezinye amakhadi abanazo. Kwaye izichazi zonke zacwangciswa ngokwe-alfabethi. Imizekelo baninzi. Uhlobo - ukulungelelanisa ngokutsha inani elithile yezinto nawuphi na umyalelo phezu kwezizathu ezichazwe. ma Ukuhlela zifuna kakuhle rhoqo. Ukuza kuthi ga ngoku, kusetyenziswa iindlela ezahlukeneyo. Ukuze siqonde ubuntu babo, lwanele siqwalasele ngokweenkcukacha ngeendlela eziliqela.

Yintoni ekwenza

Kubalulekile ukuqonda ukuba uluhlu ibandakanya ngababini ezininzi yezitshixo kunye nemilinganiselo ethile. ma Ukuhlela C lwenziwa ngoncedo abaninzi imigca ikhowudi, nolwimi PHP, oku kuphunyezwa enye kuphela umyalelo elula. Ukuhlela ma kunokwenzeka ngenxa indibaniselayezitshixo okanye amaxabiso. Kunjalo kunokwenzeka ukuba asasaze ixabiso, wabashiya ngamaqhosha ezikhoyo okanye anike ezintsha.

Umahluko omkhulu kwemisebenzi

Ukuhlela afanayo PHP kunokwenzeka besebenzisa imisebenzi eyahlukeneyo. Makhe sijonge ukuba ahluke njani:

- Eminye imisebenzi ezibekwe kwimiboniso ngu izinto zayo, kunye nabanye - on kumaxabiso.

- kukho umyalelo uhlobo ezahlukeneyo: ekwehleni, ukukhula, zendalo, amanani, alfabhethi, abasebenzisi random okanye ezichaziweyo.

- Eminye imisebenzi bayakwazi ukugcina emva yokuhlela uqhagamshelwano phakathi isitshixo kunye nexabiso. Kodwa kukho inkalo apho izitshixo aya kutsha ukuya ixabiso elitsha.

- umsebenzi nganye inika nenguqulo uluhlu wadlula. Uhlobo khuphela, abasayi kubuyela kulo.

- Umyalelo uhlobo ayicacisiswanga, xa umsebenzi imisela iziqalelo emibini iyalingana. Le uhlelwe ezingazinzanga.

Abanye uhlobo umsebenzi lens kwi PHP

Uhlobo () kunye rsort (). Uhlobo () uyala ukuba uluhlu zilandelelana ngokwe-alfabhethi. Makhe qaphela ukuba lo msebenzi ngumzekelo onovakalelo. Oku ihlelwa ziinqobo ngaphandle izitshixo. Rsort () ziya kuhlelahlelwe ukuze reverse, kakhulu, ngokutsho neenqobo abasoloko nezitshixo.

Asort () - yenye wemisebenzi wokulondoloza ulwalamano indibaniselayezitshixo nokuxabiseka. Iluncedo kwimiboniso associative, xa kubalulekile.

Kumzekelo ekhethiweyo amagama angundoqo iziqhamo kunye neemfundiso - oku ixabiso. Ukuhlela unyuka ixabiso. Ukuba ufuna uhlelahlele amagama zeziqhamo, kufuneka sisebenze ksort (), nto leyo eyenza nokuhlela yi izitshixo. Arsort () ukuhlela i uluhlu-liyajikeleza kunye nezalathiso (esichazayo) amaxabiso zisihla. Krsort () zisihla izinto uhlobo engundoqo.

Le uluhlu okuntlandlo-mbini

An umdla uluhlu okuntlandlo-mbini yokuhlela. Oku kungenziwa ngeendlela ezahlukeneyo. PHP unethuba ukuthelekisa amanani amabini okanye imitya emibini. Kuyo nayiphi na uluhlu multi kumacala-, isiqalelo ngasinye ababakhe uluhlu. E PHP, ukuthelekisa kwimiboniso ezininzi, kufuneka udale indlela ethile. Cinga uluhlu ezikumila kumacala mabini, nto leyo igcina igama elifinyeziweyo iziqhamo, igama elipheleleyo kunye nexabiso. Iziqalelo uluhlu nga mazisotwe ngokolandelelwano lwealfabhethi igama elifinyeziweyo.

Kumzekelo egameni lethu le umsebenzi thelekisa (uthelekiso). It has 2 iingxoxo - x, y. Lo msebenzi kufuneka athathe amaxabiso amabini, ngoko ukumisela umyalelo. I parameters x, y - 2 uluhlu ezo ngaphakathi uluhlu y engundoqo. Ukuze ukuthelekisa inkcazo-iziqalelo kwimiboniso, leyo ocande umsebenzi, kufuneka variables $ x [1], $ y [1]. In line return1 lixabiso kubuyela ikhowudi wawabizayo umsebenzi. Uluhlu lwethu yokuhlela usort () umsebenzi esekelwe. Uhlobo iya ngokutsho imithetho, echaza thelekisa () umsebenzi.

Ngoku ukuhlela lens e PHP uya kuba nani ukuqonda.
