PHP array()

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)

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);
?> 

The output of the code above will be:

Array ( [0] => Dog [1] => Cat [2] => Horse )
