<?php /** * Error Stack Implementation * * This is an incredibly simple implementation of a very complex error handling * facility. It contains the ability * to track multiple errors from multiple packages simultaneously. In addition, * it can track errors of many levels, save data along with the error, context * information such as the exact file, line number, class and function that * generated the error, and if necessary, it can raise a traditional PEAR_Error. * It has built-in support for PEAR::Log, to log errors as they occur * * Since version 0.2alpha, it is also possible to selectively ignore errors, * through the use of an error callback, see {@link pushCallback()} * * Since version 0.3alpha, it is possible to specify the exception class * returned from {@link push()} * * Since version PEAR1.3.2, ErrorStack no longer instantiates an exception class. This can * still be done quite handily in an error callback or by manipulating the returned array * @category Debugging * @package PEAR_ErrorStack * @author Greg Beaver <cellog@php.net> * @copyright 2004-2008 Greg Beaver * @license http://opensource.org/licenses/bsd-license.php New BSD License * @link http://pear.php.net/package/PEAR_ErrorStack */ /** * Singleton storage * * Format: * <pre> * array( * 'package1' => PEAR_ErrorStack object, * 'package2' => PEAR_ErrorStack object, * ... * ) * </pre> * @access private * @global array $GLOBALS['_PEAR_ERRORSTACK_SINGLETON'] */ $GLOBALS['_PEAR_ERRORSTACK_SINGLETON'] = array(); /** * Global error callback (default) * * This is only used if set to non-false. * is the default callback for * all packages, whereas specific packages may set a default callback * for all instances, regardless of whether they are a singleton or not. * * To exclude non-singletons, only set the local callback for the singleton * @see PEAR_ErrorStack::setDefaultCallback() * @access private * @global array $GLOBALS['_PEAR_ERRORSTACK_DEFAULT_CALLBACK'] */ $GLOBALS['_PEAR_ERRORSTACK_DEFAULT_CALLBACK'] = array( '*' => false, ); /** * Global Log object (default) * * This is only used if set to non-false.
