note 86383 deleted from function.rand by danbrown

Note Submitter: Anonymous Reason: integrated ---- Apologies, I botched the last post, so here's the corrected function. A function to generate numbers of any length which contain no identical digits side-by-side. i.e. 112233 <?php function randomNumber($number_of_digits=null){ $number_of_digits = ( $number_of_digits == null ) ? 1 : $number_of_digits; for($x=0;$x<$number_of_digits;$x++){ while(substr($new_number,strlen($new_number)-1,strlen($new_number)) == $r) $r = rand(0,9); $num .= $r; } return $new_number; } echo randomNumber(9); // Output: 875438104 echo randomNumber(); // Output: 8 ?>
