PHP to realize micro-trust and Lucky Red envelopes

 $r) {$rand _money = Number_format ($money _total* $r/$rand _sum, 2); if ($rand _money <= 0.01 | | Number_format (ARRAY_SUM ($ Rand_money_arr), 2) >= Number_format ($money _total, 2)) {$rand _money_arr[$key] = 0.01;} else {$rand _money_arr[$key] = $ Rand_money;}}  $max _index = $max _rand = 0;foreach ($rand _money_arr as $key = $rm) {if ($rm > $max _rand) {$max _rand = $rm; $max _index = $key;}} unset ($rand _money_arr[$max _index]);//Array_sum here ($rand _money_arr) must be less than $money_total $rand_money_arr[$max _index ] = Number_format ($money _total-array_sum ($rand _money_arr), 2) Ksort ($rand _money_arr); return $rand _money_arr;}

The above describes the PHP implementation of the red envelopes, including aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
