shuffle()
PHP shuffle() function randomly arranges the order of array cells (shuffles the array). This function assigns new keys to the elements in the array. This will delete the original keys rather than just reorder them.
Syntax:
##bool shuffle ( array &array )
Example 1:
<?php $arr = range(1,8); print_r($arr); echo '<br />'; shuffle($arr); print_r($arr); ?>
Output:
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 [6] => 7 [7] => 8 ) Array ( [0] => 6 [1] => 1 [2] => 3 [3] => 2 [4] => 5 [5] => 7 [6] => 8 [7] => 4 )
Example 2: Using associative array
<?php
$arr = array("a"=>1, "b"=>2, "c"=>3, "d"=>4, "e"=>5);
shuffle($arr);
print_r($arr);
?>Output:
Array ( [0] => 5 [1] => 2 [2] => 1 [3] => 3 [4] => 4 )
