Предварително-дефинирани константи
Константите по-долу са налични винаги като част от ядрото на PHP.
Забележка: 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) | 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.

Please note that a bug exists in Xdebug versions up to at least 2.1.2 where E_USER_DEPRECATED is not supported even in PHP 5.3.0+.

-1 is also semantically meaningless as a bit field, and only works in 2s-complement numeric representations. On a 1s-complement system -1 would not set E_ERROR. On a sign-magnitude system -1 would set nothing at all! (see e.g. http://en.wikipedia.org/wiki/Ones%27_complement)
If you want to set all bits, ~0 is the correct way to do it.
But setting undefined bits could result in undefined behaviour and that means *absolutely anything* could happen :-)

Well, technically -1 will show all errors which includes any new ones included by PHP. My guess is that E_ALL will always include new error constants so I usually prefer:
<?php
error_reporting(E_ALL | E_STRICT);
?>
Reason being: With a quick glance anyone can tell you what errors are reported. -1 might be a bit more cryptic to newer programmers.

-1 sets the error reporting to show all to include strict. Should only be used for development servers.
