Simple code for generating WeChat red packets using PHP

: This article mainly introduces the PHP code for generating red packets. For more information about PHP tutorials, see. The code is as follows:

/*** @ Param $ total [total red envelopes you want to send] * @ param int $ num [send a few] * @ return array [generate red envelope amount] */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 ); // if ($ safe_total <0) break; $ money = @ mt_rand ($ min * 100, $ safe_total * 100)/100; // Generate a random red packet amount $ total = $ total-$ money; // total remaining red packets $ wamp [$ I] = round ($ money, 2 ); // retain two valid numbers} $ wamp [$ I] = round ($ total, 2); $ returnData ['moneysum'] = $ wamp; $ returnData ['newtotal'] = array_sum ($ wamp); return $ returnData;} // test $ 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) */
