I’ve 2 array in php
$array1=array('user_id'=>'1','user_id'=>'2','user_id'=>'3'); $array2=array('invite_user_id'=>'1','invite_user_id'=>'3');
This is a result of select query wrote in codeigniter. so that is associative array. This is 2 query result one is for user list and second is for invited user list. I want check in user list which user is invited. So that I want to compare that array
foreach ($array1 as $key => $value) { if($array2[$key]->invite_user_id==$value->user_id) { echo "Matched"; } }
but it compare only 2 value of array1 with array2 3rd value is not compare. How it could compare all value of array1 and array2 in above foreach loop

I found that answer
$array1=array('user_id'=>'1','user_id'=>'2','user_id'=>'3'); $array2=array('invite_user_id'=>'1','invite_user_id'=>'3'); $invitationset = []; foreach ($array2 as $invite) { $invitationset[$invite->invite_user_id] = $invite->invite_user_id; } foreach ($array1 as $key => $value) { if(isset($invitationset[$value->user_id])){ if($invitationset[$value->id]==$value->user_id){ echo "Matched"; } } }
