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

function mt_rand_float($min, $max, $countZero = '0') {
    $countZero = +('1'.$countZero);
    $min = floor($min*$countZero);
    $max = floor($max*$countZero);
    $rand = mt_rand($min, $max) / $countZero;
    return $rand;
}

example:

echo mt_rand_float(0, 1);

result: 0.2

echo mt_rand_float(3.2, 3.23, '000');

result: 3.219

echo mt_rand_float(1, 5, '00');

result: 4.52

echo mt_rand_float(0.56789, 1, '00');

result: 0.69
