    $a=array("Dog","Cat");
    array_push($a,"Horse","Bird");
    print_r($a);
    ?>

The output of the code above will be:

    Array ( [0] => Dog [1] => Cat [2] => Horse [3] => Bird )

## Example 2

An array with string keys:

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

The output of the code above will be:

    Array ( [a] => Dog [b] => Cat [0] => Horse [1] => Bird )
