How to generate random decimals from 0 to 1 through php

Javascript's method of generating random decimals from 0 to 1 can call its own Math.random();

For example:

<script>document.write(Math.random()); // 0.5840498607140034</script>

There is in php rand,mt_randrandom methods, but neither of these two methods can generate 0~1 random decimals. We can write a method to achieve this function.
The method for php to generate random decimals from 0 to 1 is as follows:

<?php/**
 * 生成0~1随机小数
 * @param  Int   $min
 * @param  Int   $max
 * @return Float
 */function randFloat($min=0, $max=1){
    return $min + mt_rand()/mt_getrandmax() * ($max-$min);
}// 例子，创建5个0~1随机小数for($i=0; $i<5; $i++){    echo randFloat().&#39;<br>&#39;;
}?>

Output:

0.59804026251568
0.67772196544228
0.90589751205682
0.45087858822703
0.17475316774787
