The array system is sadly lacking a "set" function... I needed one that would set the pointer to the key that I specified.

So I wrote my own.

<?
$array=array();

$array['a']='lala';
$array['b']='blabla';
$array['c']='nono';

set($array, 'b');

echo current($array);
// outputs blabla

function set(&$array, $key)
{
	reset($array);
	while($current=key($array))
	{
		if($current==$key)
		{
			return true;
		}
		next($array);
	}
	return false;
	
}
?>
