PHP big turntable Winning probability algorithm example, PHP big turntable winning probability

This paper introduces the method of realizing the probability algorithm of the big Carousel of PHP, and shares it for everyone's reference. Specific as follows:

Big turntable is a lot of recent online moving in a more interesting thing, let's take a look at this big turntable winning probability algorithm and examples, I hope you have some help.

This is an app client that has the big Carousel Lottery algorithm, specifically how the lottery is certainly implemented on our service side. Here's a simple way to share the implementation code with you:

The

copy Code code is as follows: Header ("content-type:text/html; Charset=utf-8 ");
\$prize _arr = Array (
' 0 ' = = Array (' ID ' =>1, ' prize ' = ' tablet ', ' V ' =>1),
' 1 ' = = Array (' ID ' =>2, ' Prize ' + ' digital camera ', ' V ' =>5),
' 2 ' = = Array (' ID ' =>3, ' prize ' = ' speaker device ', ' V ' =>10),
' 3 ' = = Array (' Id ' =>4, ' prize ' = ' 4G usb ', ' V ' =>12,
' 4 ' = = Array (' ID ' =>5, ' prize ' = ' 10Q ', ' V ' =>22),
' 5 ' = > Array (' ID ' =>6, ' prize ' = ' = ' next time it will be able to be in oh ', ' V ' =>50),
);

\$actor =;

foreach (\$prize _arr as \$v) {
\$arr [\$v [' id ']] = \$v [' V '];
}
foreach (\$arr as & \$v) {
\$v = \$v * \$actor;
}
Asort (\$arr);
\$sum = array_sum (\$arr);//Total probability

\$rand = Mt_rand (1, \$sum);

\$result = ";///Winning Product ID

foreach (\$arr as \$k = + \$x)
{
if (\$rand <= \$x)
{
\$result = \$k;
Break
}
Else
{
\$rand-= \$x;
}
}
\$res [' yes '] = \$prize _arr[\$result -1][' Prize ');//Medium award
Print_r (\$res);

Urgency, PHP waiting to find the lucky big wheel in the probability of the algorithm, so that he can win, here or not to win the lottery tips

Come on, look at the papers.

Problems with the PHP algorithm

Your program can run and output the following:
**********

*********

********

*******

******

*****

****

***

**

*

I don't know what's wrong with you? * is the symbol, cannot sum.

I am really sorry, I still do not understand "output 55 this loses" what meaning?

The statement you added is the result of calculating 0+1+....+10, do you have any questions?
