Posted below is code that you would expect to work
<?php
$keys = shuffle(array_keys($arr));
foreach ($keys as $key) {
$arr_elem = $arr[$key];
// do what you want with the array element
}
?>
This in fact does not work because shuffle returns a boolean true or false. More accurate code using
this method would be:
<?php
$keys = array_keys($arr);
shuffle($keys);
foreach ($keys as $key) {
$arr_elem = $arr[$key];
// do what you want with the array element
}
?>
