## 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);
    ?>

The output of the code above will be:

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