Tips on Using PEAR_Error

Hi, I am looking to use multiple PEAR packages in a web application framework. One thing I am a bit stumped with is how to best generalize error handling between PEAR packages and other classes. Ultimately, I want to have all raised errors passed to a error handler class which takes appropriate action (emails error, outputs to screen, log, etc..) To the best of my understanding of the architecture of PEAR_Error, I simply have to extend my error handler class with PEAR and statically define the callback function (which in turn calls my error handler object) with PEAR::setErrorMode(PEAR_ERROR_CALLBACK, "my_function_handler"); I am most likely not doing this right, as when I raise a PEAR error, it does not init my callback function. Any help woudl be appreciated. A sample of my code follows. Michael <?php require_once('PEAR.php'); class ErrorHandler extends PEAR {

    function ErrorHandler()
    {
        $this->PEAR();
    }

function HandleError() {

      $args  = func_get_args();

// do stuff... } } function errorHandler() { static $EH = ""; if(!error_reporting()) // Check for @ error control operator return 0; if ( empty($EH) ) {

      foreach ( array_keys($GLOBALS) as $key )
      {
         if ( is_object( $GLOBALS[$key] ) )
         {
            if ( 'errorhandler' == get_class($GLOBALS[$key]) )
            {
               $EH =& $GLOBALS[$key];
               break;
            }
         }
      }

} if ( func_num_args() > 0 ) {

      $args  = func_get_args();
      call_user_func_array(array(&$EH, "HandleError"), $args);
    }
    else {
        return $EH;
    }

} PEAR::setErrorHandling(PEAR_ERROR_CALLBACK, 'ErrorHandler'); $fw_error = & new ErrorHandler(); trigger_error("test", E_USER_ERROR); //Does not call errorHandler unless I define it with set_error_handler() class test extends PEAR {

    function test($string = null)
    {
        $this->PEAR();
    }

    function run($string = null)
    {
        if (is_null($string))
            return $this->raiseError("Error");

//raised error does not call the call back function

    }

} $test = & new test(); $res = $test->run(); if (PEAR::isError($res))

    echo $res->getMessage( );
