Question

i have 2 queries, and i get back some data by doing a whyle loop.

from the first query if i do print_r($final_key);i get:

hey1
hey2
hey3

from the second one, if i do print_r($final_key2); i get:

hey1 test
hey2 test1
hey3

what i am trying to do is to compare the 2 arrays and check for words that match
and i can’t do it directly from the database

any ideas?

thanks

edit:
here is my query 1:

while ($keywords = mysql_fetch_array($keys1, MYSQL_ASSOC)){
    foreach ($keywords as $key) {
        $plus = '+';
        $pos = strripos($key, $plus);
            if ($pos === false) { } else { 
                $clean_plus = preg_replace("/[\+]/", '', $key);
                $final_key = str_replace("'", "", $clean_plus);
                print_r($final_key);
                echo '<br>';
            }


    }
} 

and the second one:

 <?php
 while ($keywords = mysql_fetch_array($keys)){
if($keywords['kword'] != ''){
    echo $keywords['kword'];
 } } ?>

i am tryingt o match $final_key against $keywords['kword'];

Answer 1

Use array_intersect which returns an array containing values in both arrays.

If you want the keys to match, use array_intersect_assoc.
