A simple probability-related code implemented in php, php probability code

The example in this article describes a simple probability-related code implemented in php. Share it with everyone for your reference, the details are as follows:

<&#63;php
for($i=1;$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 . '<br />';
echo $b . '<br />';
echo $c . '<br />';
&#63;> 

Output result:

19589
29795
50615

The key is mt_rand(0,100)

Reflect the probability by the number of occurrences of $a $b $c
