----
be aware there is a slight difference:
<?php
$array1 = array('lang'=>'js','method'=>'GET');
$array2 =
array('lang'=>'php','browser'=>'opera','method'=>'POST');
?>
BETWEEN:
<?php array_merge($array2,$array1); ?>
outputs: Array ( [lang] => js [browser] => opera [method] => GET )
notice that the repeated keys will be overwritten by the ones of $array1, maintaining those, because
it is the array that is being merged
AND
<?php array_merge($array1,$array2); ?>
outputs: Array ( [lang] => php [method] => POST [browser] => opera )
here the oposite takes place: array1 will have its elements replaced by those of array2.
