Why is passing the database link as an argument in mysql_fetch_object() unnecessary and potentially problematic?

Passing the database link as an argument in mysql_fetch_object() is unnecessary because the function already knows which database connection to use based on the last connection made. It can also be problematic because it may lead to confusion or errors if the wrong database link is passed. To solve this issue, simply remove the database link argument from the function call.

// Unnecessary and potentially problematic usage
$result = mysql_fetch_object($result, $db_link);

// Corrected code without passing database link argument
$result = mysql_fetch_object($result);
