PHP Weighted random number

How can I generate a weighted random number between 1 and 10 with 10 being the highest chance and 1 being the lowest chance?

rand(1,10) ?

Needs to be a simple one line code since it will be run 100,000's of times

Solution

  • OK I think I understand what you're trying to say..

    try this :

    mt_rand(mt_rand(1, 10),10 );

    I looped it a million times : 

    10 = 292634 
9 = 193333 
8 = 142815 
7 = 109580 
6 = 84616 
5 = 64498 
4 = 47666 
3 = 33450 
2 = 21286 
1 = 10122
