I need to generate large arrays of random numbers within specific ranges. The function provided by mark at mmpro dot de is good stuff, but if the range of your random numbers ($max - $min) is less than the number of elements in the array ($num), i.e. you want to permit duplicate values, then:

Alter this line:

 while (in_array($a,$ret));

to this:

 while (next($ret));
