Another possible way how to reverse array statically:
<?php
function arrayReverse(&$arr)
{
if (!is_array($arr) || empty($arr))
return;
$rev = array();
while ( false !== ( $val=end($arr) ) ){
$rev[key($arr)] = $val;
unset( $arr[ key($arr) ] );
}
$arr = $rev;
}
//usage:
$test = array(5, 'c'=>100, 10, 15, 20);
arrayReverse($test);
var_export($test); //outputs: array ( 3 => 20, 2 => 15, 1 => 10, 'c' => 100, 0
=> 5, )
?>
