[PHP-DEV] PHP 4.0 Bug #9386: set_error_handler() doesn't always catch errors From: stevem <email protected>
Date: 02/21/01

From: stevem <email protected>
Operating system: Red Hat Linux 6.2
PHP version: 4.0.4pl1
PHP Bug Type: PHP options/info functions
Bug description: set_error_handler() doesn't always catch errors

The files error_handler.inc, parse_error.php, and php_warning.php are included below.

We have error_handler.inc as the auto_prepend_file in php.ini. It defines an error handling function and then sets it. However, when a parse error occurs, our error handler is not called, as you can see in the following snippet of execution. It is clear that the error handler is not being called in the second case.

*******************************************
[httpd <email protected> php]$ php -q php_warning.php
ERROR HANDLER
[httpd <email protected> php]$ php -q parse_error.php
<br>
<b>Fatal error</b>: Call to undefined function: thisisjunk() in <b>parse_error.php</b> on line <b>3</b><br>
[httpd <email protected> php]$

/*
 
>From php.ini:
 
 E_ALL - All errors and warnings
 E_ERROR - fatal run-time errors
 E_WARNING - run-time warnings (non fatal errors)
 E_PARSE - compile-time parse errors
 E_NOTICE - run-time notices (these are warnings which often result from a bug in
                     your code, but it's possible that it was intentional (e.g., using an
                     uninitialized variable and relying on the fact it's automatically
                     initialized to an empty string)
 E_CORE_ERROR - fatal errors that occur during PHP's initial startup
 E_CORE_WARNING - warnings (non fatal errors) that occur during PHP's initial startup
 E_COMPILE_ERROR - fatal compile-time errors
 E_COMPILE_WARNING - compile-time warnings (non fatal errors)
