looking for function that will act like array_diff_uassoc in php 4

[sd1]

the array_diff_uassoc() is a php5 function. my webserver is running on php4, is there any way to have an equivalent function that will do the same?

Yep; write one using the functions that exist in PHP4.

// Standard disclaimer: cut-and-paste code never works
if(!function_exists('array_udiff'))
{
function array_udiff($array1, $array2, $callback)
{
	foreach($array2 as $key2=>val2)
	{
		foreach($array1 as $key1=>$val1)
		{
			if($callback($val1,$val2))
			{
				unset($array1[$key1]);
			}
		}
	}
	return $array1;
}
}

if(!function_exists('array_diff_uassoc'))
{
function array_diff_uassoc($array1, $array2, $callback)
{
	$newkeys = array_udiff(array_keys($array1), array_keys($array2), $callback);
	$newarray = array();
	foreach($newkeys as $newkey)
	{
		$newarray[$newkey]=$array1[$newkey];
	}
}
}
