Question

Is it possible to use an exception at the end of a mysql query instead of die()? I’d like to throw an exception and log it instead of killing the script.

Would it be done like:

mysql_query(...) or throw new exception()??

Answer 1

This is the way I normally do it. I have my database in a wrapper class, so $this simply refers to the wrapper.

private function throwException($query = null)
{
    $msg = mysql_error().".  Query was:\n\n".$query.
                   "\n\nError number: ".mysql_errno();
    throw new Exception($msg);
}

public function query($query_string)
{
    $this->queryId = mysql_query($query_string);
    if (! $this->queryId) {
        $this->throwException($query_string);
    }
    return $this->queryId;
}

That packages it all up with a nice error message for me, so I can see the problem query. You could keep it much simpler of course, and do:

mysql_query($sql) or throw new Exception("Problem with query: ".$sql);
