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

You may use the standard function: lcg_value().

Here's another function given on the rand() docs:

// auxiliary function // returns random number with flat distribution from 0 to 1 function random_0_1()  {     return (float)rand() / (float)getrandmax(); } 

Answer 2

Example from documentation :

function random_float ($min,$max) {    return ($min+lcg_value()*(abs($max-$min))); }
