PHP 2D and multidimensional arrays are out of order, PHP_ PHP scrambles a simple example of a two-dimensional array and a multi-dimensional array. The shuffle function in PHP can only scramble one-dim

php A simple example of a two-dimensional array and a multi-dimensional array

php Medium shuffle Functions can only scramble one-dimensional arrays , What's a quick and convenient way to scramble multidimensional arrays ？ The manual provides

function shuffle_assoc($list) {

if (!is_array($list)) return $list;

$keys = array_keys($list);

shuffle($keys);

$random = array();

foreach ($keys as $key)

$random[$key] = $list[$key];

return $random;

}

?>

The above one is for two-dimensional arrays !

The following is an unordered method for multidimensional arrays ？ As convenient and fast as possible ：

function shuffle_assoc($list) {

if (!is_array($list)) return $list;

$keys = array_keys($list);

shuffle($keys);

$random = array();

foreach ($keys as $key)

$random[$key] = shuffle_assoc($list[$key]);

return $random;

}

?>

The following functions are also from php manual , Can disrupt multidimensional arrays ：

/**

* Shuffles an associative array recursive

*

* @param array $array

* @return array

*

*/

function rec_assoc_shuffle($array)

{

$ary_keys = array_keys($array);

$ary_values = array_values($array);

shuffle($ary_values);

foreach($ary_keys as $key => $value) {

if (is_array($ary_values[$key]) AND $ary_values[$key] != NULL) {

$ary_values[$key] = rec_assoc_shuffle($ary_values[$key]);

}

$new[$value] = $ary_values[$key];

}

return $new;

}
