Php implements a simple probability-related code and php probability code.

This example describes a simple probability-related Code implemented by php. We will share this with you for your reference. The details are as follows:

<? Phpfor ($ I = 1; $ I <100000; $ I ++) {$ x = mt_rand (0,100); if ($ x <20) {$ a = $ a + 1;} else {if ($ x <50) {$ B = $ B + 1 ;} else {$ c = $ c + 1 ;}} echo $. '<br/>'; echo $ B. '<br/>'; echo $ c. '<br/>';?>

Output result:

19589
29795
50615

The key lies in mt_rand (0,100)

The probability is expressed by the number of occurrences of $ a $ B $ c.
