This function should take all elements in all arrays and flatten them down to one array.
Thus the result of the example above should be
array(1,2,..,6)

Try this:
<plaintext><?php
function fa() {
foreach ( func_get_args() AS $arg ) {
if ( is_array($arg) ) {
foreach( $arg AS $value ) {
flatten_array( $value );
}
} else {
$GLOBALS['master_arr'][] = $arg;
}
}
}
$GLOBALS['master_arr'] = array();
fa(array(1,2),array(array(3,4),array(5,6)));
print_r($GLOBALS['master_arr']);
?>
This does not preserve array keys, but you didn't mention wanting to preserve them.
