Question

I hope I am doing this correctly..

Using this code I am grabbing records from one table and storing them in an array:

$result = mysql_query("SELECT username FROM '$tbl_name'");
$storeArray = Array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
    $storeArray[] =  $row['username'];  
}

The result of the query is (using: print_r($storeArray);):

Array ( [0] => username1 [1] => username2 [2] => username3)

I want to use this array to search another table. Improvised code would be:

SELECT * FROM $users_tbl WHERE username = username1, username2, username3

Could anyone help me generate the MySQL query that would do this?

I hope this is clear enough..

Answer 1

You can do this in one query using a subquery:

"SELECT * FROM `$users_tbl` WHERE `username` IN (SELECT username FROM `$tbl_name`)"

Also note the mysql extension is being deprecated, and it is recommended to use mysqli
