generate a random number between 0 and 1 in php

You can generate a random float number between 0 and 1 in PHP using the rand function. Here's an example:

main.php
$randomNumber = rand() / getrandmax();
echo $randomNumber;
59 chars

The rand() function generates a random integer. getrandmax() returns the maximum value that can be returned by rand(). Dividing the random integer by getrandmax() gives you a float number between 0 and 1.
