Nzira ye PHP inoshanda sei?

Chirongwa chitarisiko che data chinokubvumira kuti uchengete humwe hutsika mune imwe nzvimbo iyo imwecheteyo.

Array Types

Kune mhando mbiri dzemakamuri, dzinopesana nenzira yekucherechedza zvigadziriswa.

1. Zviri nyore - mukati mazvo chimwe nechimwe chinopiwa nechinyorwa mune zvimwe zvinotevera.
2. Kushamwaridzana - inoshandisa zvigaro zvinosanganiswa zvine musoro nehutano hwekuwana chinhu ichocho.

Mukutaura kwakajeka, iyo inoshandiswa umo inogona kuva nenhamba imwe chete. Isu tinofarira PHP array.

Mamiriro ezvinhu

Funga nezveFP pane zvakawanda:

1. Inogona kuva nenhamba ipi zvayo yehutsika, uye inogonawo kuva isina chinhu.
2. Chimwe chezvinhu zvinokosha izvo zvine PHP array zvinonzi chinhu.
3. The element inochengeta marudzi akasiyana ezvimwe zvinhu. Izvi zvinogona kuva zvidzidzo, integers, zvinonzwisisika.
4. Kuwanika kwezvinhu zviripo kunogona kuburikidza nekubatsirwa kweenhamba, izvo zvose zviri mutambo uye nhamba.
5. PHP pane rine zvinhu zvine mazita akasiyana.
6. Nhamba yezvinhu zviri muhuwandu ndehurefu hwayo.
7. Iko maitiro ezvinhu zvinogonawo kuva mapurisa, saka zvinyorwa zvema-dimensional zvakasikwa.

Chimwe chinhu chakasiyana cheFP ndiko kukwanisa kuumba zvakasiyana-siyana zvekunyora mune script.

Zvirongwa:

1. Hazvisi zvakaoma kushanda panguva imwe chete nehuwandu hunokosha. Zviri nyore kutenderera kuburikidza nezvinhu zvayo nekuchinja maitiro.
2. Izvo zviri nyore kushandisa. Ingosiya, kuwedzera zvinhu, kuverenga kana kuchinja hutsika hwezvinhu.
3. Mune PHP, kune mabasa akawanda akasiyana-siyana anokubvumira kugadzirisa mabhii. Pane kutsvaga kwehumwe hutsika, kusarudza, kubatanidza mavara.

Aina

Mifananidzo yakakamurwa kuva 2 mamwe marudzi:

• One-dimensional;
• Two-dimensional.

Kune nzira dzakasiyana dzekugadzirisa matura. Chokutanga, funga nezvechimwe chinhu, uye zvakare sangano re PHP.

Muenzaniso wekusika yakajeka mu PHP:

Mumuenzaniso, kiyi ndiyo nhamba mumabhati [], uye maitiro ndiwo mazita ezvibereko nemiriwo.

Kupa kukosha kune PHP array element kunogona kunyorwa seizvi:

• $ Array [n] = z;
• N ndiro kiyi, z ishoko.

Newechipiri nzira yekutanga, haugoni kujekesa chero chipi zvacho mubhakoni mabheti :

• $ Name [] = "one";
• $ Name [] = "two";
• $ Name [] = "tatu".

Muchiitiko ichi, nhamba idzi dzichaenzana ne 0, 1 uye 2 kuburikidza.

Uye iwe unogona kupa chero hupi hwehutano hwako kune zvinyorwa:

• $ Name [35] = "one";
• $ Name [18] = "maviri";
• $ Name [90] = "vatatu".

Iwe unogona kuyananisa nzira dzokutanga:

• $ Name [37] = "kutanga";
• $ Name [5] = "wechipiri";
• $ Name [] = "chechitatu".

Chikamu chechitatu chichagoverwa chinyorwa chakaenzana ne 38, sezvo 37 ndicho chikuru pane zvinyorwa.

Izwi rechirevo chemukati wemarudzi akawanda rinoratidzika seizvi:

$ Name [index1] [index2] ....

Iye zvino ngationei kuti chii chinonzi PHP chekubatana. Nhamba yacho inogona kuva tambo, haisi kumanikidzwa, nzvimbo dzinobvumidzwa, urefu hwacho hwakasiyana. Nzira dzekubatana dzakanaka kushandisa apo iwe unoda kushamwaridzana nezvinhu zvisiri nehuwandu, asi nemashoko. Nzira dzine nheyo dzayo dzinonzi masangano.

Rimwe-dimensional associative arrays rine chinyorwa chimwe bedzi, chinopindirana nekanyorwa chaiyo. Muenzaniso uri pamusoro apa unoratidza muenzaniso we-one-dimensional uye multidimensional associative arrays.

Iwe unogona kugadzira didimenistal associative array munzira yechikoro, asi izvi hazvisi nyore.
