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 frand($min, $max, $decimals = 0) {
  $scale = pow(10, $decimals);
  return mt_rand($min * $scale, $max * $scale) / $scale;
}

echo "frand(0, 10, 2) = " . frand(0, 10, 2) . "\n";
