To shuffle keeping the keys intact, I've used the following:
<?PHP
$shuff=array("a","b","c","d","e","f","g",
"h","i","j","k","l");
uasort( $shuff, 'scmp' );
print_r($shuff);
function scmp( $a, $b ) {
return rand(-1,1);
}
?>
Example output:
Array
(
[7] => h
[6] => g
[2] => c
[0] => a
[5] => f
[4] => e
[10] => k
[3] => d
[8] => i
[11] => l
[1] => b
[9] => j
)
Array
(
[6] => g
[0] => a
[2] => c
[10] => k
[8] => i
[5] => f
[1] => b
[4] => e
[9] => j
[3] => d
[7] => h
[11] => l
)
Works for me...
