PHP生成微信红包代码简单

PHP⽣成微信红包代码简单

废话不多说了，⼀切解释尽在代码中，具体代码如下所⽰：

/**

* @param $total [你要发的红包总额]

* @param int $num [发⼏个]

* @return array[⽣成红包⾦额]

*/

function getRedGift($total, $num = 10)

{

$min = 0.01;

$wamp = array();

$returnData = array();

for ($i = 1; $i < $num; ++$i) {

$safe_total = ($total - ($num - $i) * $min) / ($num - $i); //红包⾦额的最⼤值

if ($safe_total < 0) break;

$money = @mt_rand($min * 100, $safe_total * 100) / 100;//随机产⽣⼀个红包⾦额

$total = $total - $money;//剩余红包总额

$wamp[$i] = round($money, 2);//保留两位有效数字

}

$wamp[$i] = round($total, 2);

$returnData['MoneySum'] = $wamp;

$returnData['newTotal'] = array_sum($wamp);

return $returnData;

}

//测试

$data = getRedGift(100, 10);

print_r($data);

//result:

/*

Array

(

[1] => 8.7

[2] => 10.09

[3] => 6.23

[4] => 6.87

[5] => 0.47

[6] => 3.12

[7] => 7.52

[8] => 12.21

[9] => 20.53

[10] => 24.26

)*/
