PHP implementation of a simple probability-related code, PHP probability code

This paper describes a simple probabilistic correlation code for PHP implementations. Share to everyone for your reference, 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 $a. '
'; Echo $b. '
'; Echo $c. '

Output Result:

19589
29795
50615

Key in Mt_rand (0,100)

Probability is represented by the number of occurrences of a $ A $b $c

Add: The above code is not typeset, it seems a little difficult to read, fortunately the code is not many. Small series here is recommended a site of the PHP format landscaping tools to help you in the future of PHP programming code layout, increase the readability of the code:
