[SOLVED] Has anyone made a function to merge more then 2 arrays?

[Demonic]

Has anyone tried to make a function which merges more then two arrays?  I know there is array_merge, but thats only for 2 arrays, wondering whats a quick way to merge a lot of arrays together?

well if nothing else, you could just loop the array merge...guess it kinda depends on the naming convention of your arrays.

I haven't tried it yet, but I just pieced something like this together:

 

function array_merge_alot() {
$numargs = func_num_args();
$arg_list = func_get_args();
if( $numargs <= 1 ) {
	return 0;
} elseif( $numargs == 2 ) {
	return array_merge( $arg_list[0], $arg_list[1] );
} else {
	$array = array_merge( $arg_list[0], $arg_list[1] );
	for( $x = 3; $x < $num_args - 2; $x++ ) {
		$array = array_merge( $array, $arg_list[ $x ] );
	}
	return $array;
}
}

 

Wouldn't it be:

 

for( $x = 3; $x < $num_args+1; $x++ ) {

the manual is a wonderful thing

<?php

$ar1 = array (1,2,3);
$ar2 = array (4,5,6);
$ar3 = array (7,8,9);
$ar4 = array ('a','b','c');

$array = array_merge($ar1, $ar2, $ar3, $ar4);

echo '<pre>', print_r($array, true), '</pre>';

?>

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => 7
    [7] => 8
    [8] => 9
    [9] => a
    [10] => b
    [11] => c
)

-.- I thought it was a limit to only 2, ah well thanks.

syntax from manual showing optional additional arrays

 

array array_merge ( array array1 [, array array2 [, array ...]] )
