PHP如何查找两个数组中不同元素的？本文主要介绍了PHP实现查询两个数组中不同元素的方法，涉及PHP数组差集运算与数组合并的相关技巧，需要的朋友可以参考下。希望对大家有所帮助。<?php
$a = array(
"max_allow_dialogs",
"livechat_server_ip",
"livechat_service_time",
"abort_zh_cn",
"abort_zh_tw",
"abort_en_usa",
"welcome_zh_cn",
"welcome_zh_tw",
"welcome_en_usa",
"timeout_zh_cn",
"timeout_zh_tw",
"timeout_en_usa",
"absence_zh_cn",
"absence_zh_tw",
"absence_en_usa"
);
$b = array(
"max_allow_dialogs",
"livechat_server_ip",
"livechat_service_time",
"abort_zh_cn",
"abort_zh_tw",
"abort_en_usa",
"welcome_zh_cn",
"welcome_zh_tw",
"welcome_en_usa",
"timeout_zh_cn",
"timeout_zh_tw",
"timeout_en_usa",
);
$c = array_merge(array_diff($a,$b),array_diff($b,$a));
print_r($c);
?> 结果： Array
(
[0] => absence_zh_cn
[1] => absence_zh_tw
[2] => absence_en_usa
)
