Random Float in php

Is it possible to create a random float number between 0 and 1.0 e.g 0.4, 0.8 etc. I used rand but it only accepts integers.

Answer 1

mt_rand() / mt_getrandmax();

Avoid the rand() function, since it usually depends on the platform's C rand() implementation, generally creating numbers with a very simple pattern. See this comment on php.net
