sql - PHP Loops and Arrays


How can I list all array items except that there is another Array ? Example:

First array:

$idea_id[$row["id"]] = $row["id"];

Second array:

$m_voted[$votedke] = $row["ideaid"];

Keeping this datas in separate SQL tables. And how to list all$idea_id but if

$idea_id[this_item] == $m_voted[any_item]

thenthis item not listing.




From your question what i understand is you want to check the data exists in the second array.

You can usein_array function which check if the idea_id is in m_voted array

foreach($idea_id as $id){
       echo "{$id}<br/>";
