if the query of a database fails this will print out error to user and in the log file.

This will echo the file and line of the error, the error, and the faulty query. This will also prevent mysql_fetch_array() from printing an error when $result does not exist.

<!---Head--->
none

<!---Body--->


 <?
$query = "SELECT * FROM table";
$result = mysql_query($query);
If (!$result) {
// hidden debug info
echo "nn<!--" __FILE__ . ":" . __LINE__ . "-->n";
echo "<!--QUERY ERROR:" . mysql_error() . "-->n";
echo "<!--QUERY:$query-->nn";

// message to user that there was an error
echo "An error occured while trying to _fill_in_the_blank_.n";
}

While ($result && $row = mysql_fetch_array($result)) {
// do something
}
?>
