Constantes pré-définies
Providing an example...
eac_error.class is a PHP static utility class for error handling. It is intended to be used throughout the PHP application for capture and reporting of errors and exceptions.
The error handling routine in eac_error.class is designed to provide detailed state information for the developer or administrator while still maintaining a secure environment. Error messages are only presented to the web user on true error conditions and do not include information that may be used to compromise the system. Notifications are sent to the webmaster/administrator in an encrypted state (using GnuPG) so that critical, private information cannot be intercepted in transit.
Features
GnuPG encrypted email sent to the web administrator.
Detailed system information included with email.
Function and class trace back information included.
Log errors to a single file or multiple files based on severity (fatal, error, warning ,notice).
Send email notice for each error or for all errors at the end of script execution.
Suppress or allow options (email, display, logging, etc.) when error is triggered.
Provide a program-designated error code with the error message.
Set a callback function to display errors and abort processing.
Include user-defined data in the error notification email.
Error condition detectable by AJAX and CURL.

Exemples
Ci-dessous, vous trouverez un exemple de gestion des erreurs par PHP. Il y est défini un gestionnaire d'erreur, qui enregistre les informations dans un fichier (au format XML), et envoie un courriel au développeur si l'erreur est critique.
Exemple #1 Gestion d'erreurs avancées en PHP
<?php
// Nous allons faire notre propre gestion

// Fonction spéciale de gestion des erreurs

// Définit un tableau associatif avec les chaînes d'erreur
// En fait, les seuls niveaux qui nous interessent
// sont E_WARNING, E_NOTICE, E_USER_ERROR,
// E_USER_WARNING et E_USER_NOTICE
$errortype = array (
E_ERROR => 'Erreur',

E_COMPILE_ERROR => 'Compile Error',
E_COMPILE_WARNING => 'Compile Warning',
E_USER_ERROR => 'Erreur spécifique',
E_USER_WARNING => 'Alerte spécifique',
E_USER_NOTICE => 'Note spécifique',
E_STRICT => 'Runtime Notice',
