<?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 ) |
