Question

I am trying to query a database, but it seems to just load for an age and not do anything. It’s a simple query and shouldnt take longer than a millisecond.

while($row = mysql_fetch_array(getWallPosts($userid)))
{
}

Now when I replace this code with:

echo mysql_num_rows(getWallPosts($userid));

It just displays ‘1’ in fact there’s only one record in the DB and it’s just a simple SELECT statement.

Here’s the getWallPosts function:

function getWallPosts($userid, $limit = "10")
{
    $result = dbquery("SELECT * FROM commentpost 
                           WHERE userID = ".$userid." 
                           ORDER BY commentPostID DESC LIMIT 0, ".$limit);
    return $result;
}

Also, when I put the SQL string that it’s executing into MySQL’s query browser. It takes no time at all.

Any ideas?

You appear to be looping indefinitely because you’re retrieving a new set (one record) of data each time.

$result = getWallPosts($userid);

while ($row = mysql_fetch_array($result)) {
    //printf($row[0]);  
}
