Selecting a random element from a PHP associative array

Question

I\'ve got an associative array in PHP and want to select a random key/value pair out of it. Here\'s what I have so far:

Initialize.

$locations = arra         


        

Answer 1

array_rand() returns a key from the array, not a value. You can just use:

$location_name = $locations[$rand];

To get the location name.

Here's a full example: http://codepad.org/zR2YdMGN

Just click submit a few times, you'll see the random working.
