[SOLVED] Calculating a percentage?

[JaTochNietDan]

How would you, calculate a percentage? Like say I want there to be a 30% chance of this topic to be posted when I click post? I tried messing with rand(0,10) but I dont think that would account for percentages correctly. Is there a function?

 

Thanks for any replies

if(rand(1,100) <= 30){
  echo "30% of the time";
}

 

p.s. - if your percentages are divisible by 10, you can use 1-10 and 3 instead
