Array

An array is a sequence of elements. Elements could be in different types, elements also could be array. An array is a set of key-value pair, contains all unique keys. Keys could be number, string

Types of element’s value could be mixed

Declare:

Use [] operator to declare value for arrays.

$array : [0=>a,1=>b, 2=>c] // with keys

$array_mixed_type : [1, hello, true, [4.6, false]] // auto key, auto-increase from 0, 1, …

Get/assign value for element:

Use $array_var_name[key]

(Using above array declarations)

$array[1]

> b

$array[0] : test

$array[0]

> test

$array_mixed_type [3][2]

> false

Or

$array_mixed_type [3,2]

> false

$array_mixed_type [3,2] : true

$array_mixed_type [3][2]

> true

Add new element to array:

$array[]: d

You could iterate through array, see section about looping for detailed.
