隐身守侯 提交于 2019-12-23 07:26:11

Random value from array by weight in php

家住魔仙堡 提交于 2019-12-19 05:24:12
问题 I understand that this question has likely been asked, but I don't understand the prior questions enough to know if they do what I want. $fruits = array('20' => 'apple', '40' => 'orange', '40' => 'pear'); The keys are percentages of the chance of value getting picked. I would like to mt_rand() a number between 0 and 99 and return a value from $fruits based on those percentages. It's very possible I'm so confused because I don't know how to explain what I'm looking for. Thank you in advance
