PHP implements a method to query two different elements in an array, the PHP array

This article describes the PHP implementation of querying two different elements in the array method. Share to everyone for your reference, as follows:

<?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);? >

Results:

Array (  [0] = ABSENCE_ZH_CN  [1] = ABSENCE_ZH_TW  [2] = Absence_en_usa)
