PHP equivalent of javascript Math.random()?
function random(){
return mt_rand() / (mt_getrandmax() + 1);
}
Javascript's Math.random gives a random number between 0 and 1. Zero is a correct output, but 1 should not be included. @thiagobraga's answer could give 1 as an output. My solution is this:
This will give a random number between 0 and 0.99999999953434.

@elclanrs solution is easier and doesn't need the cast in return.
There's a good question about the difference between PHP mt_rand() and rand() here:What's the disadvantage of mt_rand?
You could use a function that returns the value:
