[SOLVED] Random Percentage

[rascle]

Hi

I am creating an online game and i want there to be an $value which is a percentage so lets say 70% and then i want $random number to generate a number that is likely according to the percentage so if the percentage is 70% then $random would more likely to be yes than no. If $value was 30% then $random would more likely to be no than yes and so on and so forth!

I know that you could probaly do that using arrays but the only way i could think of doing it would take a long time. Also in the code please bear in mind that $value is dependant on whether the player has a certain objects or whatever.

Thanks

Rhys

off the top of my head...this should work

<?php
  $chance = 70;
  if(rand(0,100) <= $chance){
    print "Yes";
  }else{
    print "No";
  }
?>

 

edit: That will give you "Yes" 70% of the time
