Select random file from directory

Question

You can use glob to get all files in a directory, and then take a random element from that array. A function like this would do it for you:

function random_pic($dir = 'uploads')
{
    $files = glob($dir . '/*.*');
    $file = array_rand($files);
    return $files[$file];
}

I've turned it a little to get more than one random file from a directory using array.

<?php

function random_pic($dir)
{
 $files = glob($dir . '/*.jpg');
 $rand_keys = array_rand($files, 3);
 return array($files[$rand_keys[0]], $files[$rand_keys[1]], $files[$rand_keys[2]]);
}

// Calling function

list($file_1,$file_2,$file_3)= random_pic("images"); 

?>

You can also use loop to get values.
