This article describes how to implement the php red packet distribution algorithm. We will share this with you for your reference. The details are as follows:

/*** Red packet distribution: randomly allocate a certain amount to a specified number of people ** @ param int $ money is used to allocate the amount * @ param int $ num Number of people allocated */function RandomMoney ($ money, $ num) {echo "$ money is randomly divided into $ num parts: <br/>"; $ remain = $ money; $ use = 0; for ($ I = 1; $ I <$ num; $ I ++) {$ temp = rand (0, $ remain * 100)/100; echo "balance :". $ remain. ", used :". $ use. ", allocation :". $ temp. "<br/>"; $ use + = $ temp; $ remain-= $ temp;} echo "balance :". $ remain. ", used :". $ use. ", allocation :". $ remain;} echo RandomMoney (10, 5 );
