Introduction to using SabreAMF with Flex

2008-01-02 4:15 am 5 Comments , and

Wil wrote a pretty good introduction to using SabreAMF with flex. He's making use of the Zend autoloader to load the classes. If you're new to SabreAMF, this might be a good starting point.

He also mentions its best to set display_errors to 0, to suppress PHP errors. I personally prefer re-throw all PHP errors as exceptions using the following class:

  1. <?php
  2.  
  3.     /**
  4.      * This is a default exception wrapper for PHP errors.
  5.      * This allows you to deal with PHP errors as exceptions (using try..catch blocks etc..)
  6.      *
  7.      * @uses Exception
  8.      * @package Sabre
  9.      * @subpackage PHP
  10.      * @version $Id: Exception.php 733 2007-05-15 22:04:52Z evert $
  11.      * @copyright Copyright (C) 2007 Rooftop Solutions. All rights reserved.
  12.      * @author Evert Pot (http://www.rooftopsolutions.nl)
  13.      */
  14.     class Sabre_PHP_Exception extends Exception {
  15.  
  16.         /**
  17.          * __construct
  18.          *
  19.          * @param string $message
  20.          * @param string $code
  21.          * @param string $file
  22.          * @param int $line
  23.          * @return void
  24.          */
  25.         function __construct($message,$code=false,$file=false,$line=false) {
  26.  
  27.             parent::__construct($message,$code);
  28.             $this->file = $file;
  29.             $this->line = $line;
  30.  
  31.         }
  32.  
  33.         /**
  34.          * Register this class as an error handler
  35.          *
  36.          * @return void
  37.          */
  38.         static function register() {
  39.        
  40.             set_error_handler(array('Sabre_PHP_Exception','handleError'));
  41.            
  42.         }
  43.  
  44.         static function unregister() {
  45.  
  46.             restore_error_handler();
  47.  
  48.         }
  49.  
  50.         /**
  51.          * handleError
  52.          *
  53.          * @param string $code
  54.          * @param string $message
  55.          * @param string $file
  56.          * @param int $line
  57.          * @return void
  58.          */
  59.         static function handleError($code,$message,$file,$line) {
  60.            
  61.             if (!$code) return;
  62.             throw new self($message,$code,$file,$line);
  63.  
  64.         }
  65.  
  66.     }
  67.  
  68. ?>

Simply call Sabre_PHP_Exception::register();, and you're off..

    So you fixed it?

  4. 512 blaz 2008-09-26 6:29 am

    yes thanks,

    The probleme was coming from my code because i catch Exception somewhere and i return the exceptions :S

    I have seen this part of code in CallbackServer.php that help me :

    $response = new SabreAMF_AMF3_ErrorMessage($request['data']);
    $response->faultString = $e->getMessage();
    $response->faultCode = $e->getCode();
    $response->faultDetail = $detail;

    thanks
