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;
}
?>
