本文主要和大家分享PHP查詢兩個數組中不同元素的代碼希望能協助到大家。

<?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);?>

結果:

Array(  [0] => absence_zh_cn  [1] => absence_zh_tw  [2] => absence_en_usa)
