Complete PHP Array Reference

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 1

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

The output of the code above will be:

Array ( [a] => Dog [b] => Cat [c] => Horse )

Example 2

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