以下实例讲述了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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 | <?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
)
