The connections are setup as follows:
$$link = mysqli_connect($server, $username, $password, $database);

Everything seems to work, except these errors keep showing up in error-log:
[21-Sep-2012 22:42:05 UTC] PHP Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, null given in /home/**/public_html/**/database-mysqli.php on line 138
[21-Sep-2012 22:42:08 UTC] PHP Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, null given in /home/**/public_html/**/database-mysqli.php on line 138


1 error for each click I do.

Line 138:
return mysqli_fetch_array($db_query, $type);


The full function:

function tep_db_fetch_array($db_query, $type=MYSQLI_ASSOC) { return mysqli_fetch_array($db_query, $type); }

So, I tried this and I don't appear to be getting anymore errors - is this a proper way to handle this?

function tep_db_fetch_array($db_query, $type=MYSQLI_ASSOC) { if ($db_query){ return mysqli_fetch_array($db_query, $type); } }
