Tratar los errores php de una pagina con una funcion de error propia

[neodani]

No sé como evitar que me escriba en el fichero de log el texto 2 veces.

¿Qué os parece la función que he encontrado?

Código PHP:

/*******************************************************************************

                  It handles erros in customized way

class Error
{
    var $logfile;
    var $debug;
   
/*==============================================================================
Constructor
Arguments :- $debug_yesno. If 1 then errors will be logged,else displayed
==============================================================================*/
    function Error($debug_yesno=0,$logfile_path)
    {
        $this->debug=$debug_yesno;
        $this->printdebug=1;
 
        //Report only user generated error messages
        error_reporting(E_ALL|E_USER_ERROR|E_USER_WARNING|E_USER_NOTICE);     
       
        if($this->debug>=1)
        {
            $this->logfile=$logfile_path;
            set_error_handler(array($this,"ErrorHandler"));
        }
        else
        {
            restore_error_handler();
        }
    }       
   
/*==============================================================================
Following function logs an error message
==============================================================================*/
    function ErrorHandler($errno,$errstr,$errfile,$errline)
    {
            $errtime=date("H:i:s - d/m/y");
            $error_message="An error occured on ".$errtime."\n";
            $error_message .="Details are as follows\n";
            $error_message .="Error Number : $errno\n";
            $error_message .=$errstr."\nOccured in ".$errfile."\n";
            $error_message .="On Line $errline \n\n";
            $error_message .=str_repeat("-",50);
            $error_message .="\n";
            $fp=fopen($this->logfile,"a");
            fwrite($fp,$error_message);
            fclose($fp);
    }
 
/*==============================================================================
Following function prints debug messages on the screen
==============================================================================*/
    function PrintDebug($message,$yesno=0)
    {
        if($yesno>0)
        {
            $message="<font face=\"verdana\" size=\"2\" color=\"red\">Debug : ".$message."</font><br>";
            print $message;
        }
    }
}
?>
 
<?
//If initialized with 1 errors will be logged. else they will be displayed on the screen
$error=new Error(1,"err.log.txt");
 
$conn=mysql_connect('localhost','root','12345');
 
if(!$conn)
{
    trigger_error("Couldn't Connect To MySQL Because Of Following Error :".MySQL_Error());
    $error->PrintDebug("No se puede conectar a la base de datos",1);
    die();
}
else
{
    $error->PrintDebug("MySQL Connected",1);
   
    $dblink=mysql_select_db($dbname);
    if(!$dbname)
    {
        trigger_error("Couldn't Select Database For Following Error :".MySQL_Error());
        die();
    }   
    else
    {
        $error->PrintDebug("Database Selected",1);
    }
}
?>
 

Si os fijáis cada vez que da el error esta se repite 2 veces una por esa linea

$conn=mysql_connect('localhost','root','12345');

y otra por esta

trigger_error("Couldn't Connect To MySQL Because Of Following Error :".MySQL_Error());

Y el código de error son distintos, en uno devuelve un 2 y en otra el 1024...

¿Por qué, si son el mismo error no?
¿Cual de los errores es el bueno xD? se puede hacer que solo devuelva el segundo?
Lo intenté con $conn=@mysql_connect('localhost','root','12345'); pero creo que la @ es para que no aparezca el error por pantalla, en el fichero de log lo escribe igual, correcto?
