PHP Tutorial Mt_rand () random number function
Mt_rand () returns a random integer using the Mersenne twister algorithm.

Grammar
Mt_rand (Min,max) description
If no optional parameter min and Max,mt_rand () are provided, the pseudo-random number between 0 and Rand_max is returned. For example, want a random number between 5 and 15 (including 5 and 15), with Mt_rand (5, 15).

In the previous version of 3.0.7, Max was meant to be range. To get the same random number from the previous example of 5 to 15 in these versions, the short example is Mt_rand (5, 11).
