标识调用函数的行

Question

Having a repetitive code like so:

$SQL = " INSERT INTO ... ";

mysql_query($SQL, $conexion);
$error = mysql_error();

if($_ADM['id_user']==1) {
    if( ! empty($error)) {
        $debug = array(
                    'message' => "SQL Error in news_edit module.",
                    'line'    => '177',
                    'error'   => $error,
                    'SQL'     => $SQL
                );
        exit(print_r($debug));
    }
}

This is a common code, that repeats its self every time $SQL changes. What I'm trying to achieve is a way to debug if any error occurs and as I you can see, I have the line parameter which contains the number line where last mysql_query was executed, but I have to type that manually and every time I add code before it, the line parameters needs to be changed with the new line value.

Is there any way of identifying where was last time mysql_query executed? Any other way of improving the code above?

I think what you want is debug_backtrace function. Check the manual for specs:
