Generate a random float number between 0 to 1Use a random. random() function of a random module to generate a random float number uniformly in the semi-open range [0.0, 1.0) . Note: A random() function can only provide float numbers between 0.1. to 1.0.
The rand() function generates a random integer. Example tip: If you want a random integer between 10 and 100 (inclusive), use rand (10,100). Tip: As of PHP 7.1, the rand() function has been an alias of the mt_rand() function.
The mt_rand() function is a drop-in replacement for the older rand(). It uses a random number generator with known characteristics using the » Mersenne Twister, which will produce random numbers four times faster than what the average libc rand() provides.
In PHP, the Float data type is used to set fractional values. A float is a number with a decimal point and can be extended to exponential form. Float is also called a floating-point number. Various ways to represent float values are 3.14, 4.75, 5.88E+20, etc.
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
Update: In php 7.1 the rand()has been changed and is now merely an alias of mt_rand(). Therefore it is now ok to use rand(), too.
