sketch, your first code snippet has an off-by-one error related to the $cnt variable. It needs to be count()-1 for the loops and calls to rand else you'll get "Undefined offset" notices.

Also, what's the harm in using something like the following instead of the longer, looping code snippet?

PHP Code:


			
$words = 'I took my dog for a walk';

$shuffled = explode(' ', $words);

shuffle($shuffled);

echo implode(' ', $shuffled);
