For the record, the E_DEPRECATED error thrown on is_a() has been removed in 5.3.
Additionally E_USER_DEPRECATED has been conveniently added for user generated deprecation errors.
Предопределенные константы
Перечисленные ниже константы всегда доступны как часть ядра PHP.
Замечание: You may use these constant names in php.ini but not outside of PHP, like in httpd.conf, where you'd use the bitmask values instead.
| Value | Constant | Description | Note |
|---|---|---|---|
| 1 | E_ERROR (integer) | Fatal run-time errors. These indicate errors that can not be recovered from, such as a memory allocation problem. Execution of the script is halted. | |
| 2 | E_WARNING (integer) | Run-time warnings (non-fatal errors). Execution of the script is not halted. | |
| 4 | E_PARSE (integer) | Compile-time parse errors. Parse errors should only be generated by the parser. | |
| 8 | E_NOTICE (integer) | Run-time notices. Indicate that the script encountered something that could indicate an error, but could also happen in the normal course of running a script. | |
| 16 | E_CORE_ERROR (integer) | Fatal errors that occur during PHP's initial startup. This is like an E_ERROR, except it is generated by the core of PHP. | since PHP 4 |
| 32 | E_CORE_WARNING (integer) | Warnings (non-fatal errors) that occur during PHP's initial startup. This is like an E_WARNING, except it is generated by the core of PHP. | since PHP 4 |
| 64 | E_COMPILE_ERROR (integer) | Fatal compile-time errors. This is like an E_ERROR, except it is generated by the Zend Scripting Engine. | since PHP 4 |
| 128 | E_COMPILE_WARNING (integer) | Compile-time warnings (non-fatal errors). This is like an E_WARNING, except it is generated by the Zend Scripting Engine. | since PHP 4 |
| 256 | E_USER_ERROR (integer) | User-generated error message. This is like an E_ERROR, except it is generated in PHP code by using the PHP function trigger_error(). | since PHP 4 |
| 512 | E_USER_WARNING (integer) | User-generated warning message. This is like an E_WARNING, except it is generated in PHP code by using the PHP function trigger_error(). | since PHP 4 |
| 1024 | E_USER_NOTICE (integer) | User-generated notice message. This is like an E_NOTICE, except it is generated in PHP code by using the PHP function trigger_error(). | since PHP 4 |
| 2048 | E_STRICT (integer) | Run-time notices. Enable to have PHP suggest changes to your code which will ensure the best interoperability and forward compatibility of your code. | since PHP 5 |
| 4096 | E_RECOVERABLE_ERROR (integer) | Catchable fatal error. It indicates that a probably dangerous error occured, but did not leave the Engine in an unstable state. If the error is not caught by a user defined handle (see also set_error_handler()), the application aborts as it was an E_ERROR. | since PHP 5.2.0 |
| 8192 | E_DEPRECATED (integer) | Run-time notices. Enable this to receive warnings about code that will not work in future versions. | since PHP 5.3.0 |
| 16384 | E_USER_DEPRECATED (integer) | User-generated warning message. This is like an E_DEPRECATED, except it is generated in PHP code by using the PHP function trigger_error(). | since PHP 5.3.0 |
| 30719 | E_ALL (integer) | All errors and warnings, as supported, except of level E_STRICT in PHP < 6. | 32767 in PHP 6, 30719 in PHP 5.3.x, 6143 in PHP 5.2.x, 2047 previously |
The above values (either numerical or symbolic) are used to build up a bitmask that specifies which errors to report. You can use the bitwise operators to combine these values or mask out certain types of errors. Note that only '|', '~', '!', '^' and '&' will be understood within php.ini.

In PHP 5.3 E_DEPRECATED will be added with value 8192.
Deprecated things like is_a() will throw E_DEPRECATED instead of E_STRICT.
We had our own error handler, and it caught 'Unknown' errors after upgrading to php 5.3 (nightly).
We found out it was 8192, an undocumented error.
After some searching we found out PHP 5.3 throws E_DEPRECATED errors.
