Definition and Usage

array() creates an array, with keys and values. If you skip the keys when you specify an array, an integer key is generated, starting at 0 and increases by 1 for each value.

Syntax

array(key => value)

Parameter Description
key Optional. Specifies the key, of type numeric or string. If not set, an integer key is generated, starting at 0
value Required. Specifies the value


Example

<?php
$a=array("a"=>"Dog","b"=>"Cat","c"=>"Horse");
print_r($a);
?>
