PHP实现查询两个数组中不同元素的方法

本文实例讲述了PHP实现查询两个数组中不同元素的方法。分享给大家供大家参考，具体如下：

<?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）
