array_rand — Pick one or more random entries out of an array
This function can be used to fetch one or more elements from an array in php.
Example:
<?php
$a = array(1,2,3,4,5);
$result = array_rand($a);
echo $result;
?>
This will chose a random number from the array $a.
To chose more than one random element from array we have to pass a second argument.
Example:
<?php
$a = array(1,2,3,4,5);
$result = array_rand($a,2);
echo $result;
?>
This returns two random elements.
