If you need to reverse an array by reference, you can use the following function.
<?
function &array_reverse_ref(&$a) {
$r = array();
for($i=0, $j=count($a); $i<count($a); $i++, $j--) {
$r[$i] =& $a[$j-1];
}
return $r;
}
?>
Use it like:
<?
class t {
var $message = "message";
}
for($i=0; $i<10; $i++) {
$a[] = new t();
}
$ra =& array_reverse_ref($a);
$a[0]->message = "now... this works in both";
$ra[0]->message = "but.... does not work in both";
for($i=0; $i<10; $i++) {
echo $ra[$i]->message; echo "<br>\n";
}
echo "<br>\n";
for($i=0; $i<10; $i++) {
echo $a[$i]->message; echo "<br>\n";
}
?>
