Probiers mal hiermit:
array array_merge ( array array1 [, array array2 [, array ...]] )


array_merge() merges the elements of one or more arrays together so that the
values of one are appended to the end of the previous one. It returns the
resulting array. 

If the input arrays have the same string keys, then the later value for that
key will overwrite the previous one. If, however, the arrays contain numeric
keys, the later value will not overwrite the original value, but will be
appended. 

If only one array is given and the array is numerically indexed, the keys
get reindexed in a continuous way. 

Example 1. array_merge() example

<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?>  
The above example will output:

Array
(
    [color] => green
    [0] => 2
    [1] => 4
    [2] => a
    [3] => b
    [shape] => trapezoid
    [4] => 4
)
