Random Float between 0 and 1 in PHP

Question

How does one generate a random float between 0 and 1 in PHP?

I\'m looking for the PHP\'s equivalent to Java\'s Math.random().

Answer 1

Solution for PHP 7. Generates random number in [0,1). i.e. includes 0 and excludes 1.

function random_float() {
    return random_int(0, PHP_INT_MAX-1)/PHP_INT_MAX;
}
