PHP Carousel Draw Interface instance, PHP Carousel Draw

This paper describes the implementation of the PHP Carousel draw interface. Share to everyone for your reference. Specific as follows:

Here the Carousel lottery randomly returns a turntable angle, the probability can be defined by itself

The lottery_get.php interface files are as follows:

Copy CodeThe code is as follows: <?php
/*session_start ();
if (!isset ($_session[' zaszh_user_id ')) {
echo json_encode (' status ' = ' error ', ' msg ' = ' + ' connection timeout, please reopen the page. '));
Exit
}
$user _id = $_session[' zaszh_user_id '];*/

$user _id = 1; For testing

Turntable area
$arr _area = Array (
' 0 ' = = Array (' Min_angle ' =>1, ' max_angle ' =>45, ' prize ' = ' millet '),
' 1 ' = = Array (' Min_angle ' =>46, ' max_angle ' =>90, ' prize ' = ' Pat '),
' 2 ' = = Array (' Min_angle ' =>91, ' max_angle ' =>135, ' prize ' = ' 10 Yuan '),
' 3 ' = = Array (' Min_angle ' =>136, ' max_angle ' =>180, ' prize ' = ' 5 Yuan '),
' 4 ' = = Array (' Min_angle ' =>181, ' max_angle ' =>225, ' prize ' = ' Thank you for participating '),
' 5 ' = = Array (' Min_angle ' =>226, ' max_angle ' =>270, ' prize ' = ' Thank you for participating '),
