Hi there,
Have you tried running your sql statement straight through your SQL command interface (like phpMyAdmin). If that returns no errors, try adding some error catching as follows and check the results:

$query = 'SELECT * FROM `security` LIMIT 0 , 30';
$result = mysql_query($query, $conn);
if (mysql_numrows($result) > 0)
{
$row = mysql_fetch_assoc($result);
$a = array_search($user, $row);
echo $a;
} else {
echo "No rows returned";
}

Thanks for the help but the same error appears and the query works in sql. Is there any more actions that you can recommend me to fix this error?

Try this, it seems that the $result variable is set to NULL when you try and retrieve rows from it, if you are sure that your sql is correct, are you certain that you are connecting to your database correctly? I notice that you aren't passing a username or password to your mysql_connect() statement. But if that is also fine then try this:

$query = 'SELECT * FROM `security` LIMIT 0 , 30';
$result = mysql_query($query, $conn);
if (mysql_numrows($result) == 0)
{
echo "Result set is EMPTY";
} else if (!$result) {
echo "Result set is NULL";
} else {
echo "Result set is VALID";
$row = mysql_fetch_assoc($result);
$a = array_search($user, $row);
echo $a;
}

Apart from that, I'm pretty much out of ideas, hope this helps

Thanks for the help!!!
It worked finally. You were a great help
