an extension of some previous notes to shuffle two-dimensional arrays:
-preserves main arrays keys
-shuffles every internal array the same
<?php
function array_multishuffle($array = array()){
$key = key($array);
$count = count($array[$key]);
$keys = range(0,$count-1);
shuffle($keys);
$new_array = array();
while($sub_array = current($array)){
$name = key($array);
foreach($keys as $key){
$new_array[$name][] = $sub_array[$key];
}
next($array);
}
return $new_array;
}
$array = array(
'id'=>array(10,20,30,40),
'name'=>array('bob','sam','ken','hermenegildo')
);
print_r(array_multishuffle($array));
/*
Array (
[id] => Array (
[0] => 20
[1] => 40
[2] => 10
[3] => 30
)
[name] => Array (
[0] => sam
[1] => hermenegildo
[2] => bob
[3] => ken
)
)*/
?>
