Resource Types
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+.
Predefined Constants
The constants below are always available as part of the PHP core.
Note: 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.
|
|
| 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.
|
|
| 64 |
E_COMPILE_ERROR
(integer)
|
Fatal compile-time errors. This is like an E_ERROR,
except it is generated by the Zend Scripting Engine.
|
|
| 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.
|
|
| 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().
|
|
| 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().
|
|
| 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().
|
|
| 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 but not included in E_ALL until PHP 5.4.0 |
| 4096 |
E_RECOVERABLE_ERROR
(integer)
|
Catchable fatal error. It indicates that a probably dangerous error
occurred, 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 |
| 32767 |
E_ALL
(integer)
|
All errors and warnings, as supported, except of level
E_STRICT prior to PHP 5.4.0.
|
32767 in PHP 5.4.x, 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.

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.

The following code expands on Vlad's code to show all the flags that are set. if not set, a blank line shows.
<?php
$errLvl = error_reporting();
for ($i = 0; $i < 15; $i++ ) {
print FriendlyErrorType($errLvl & pow(2, $i)) . "<br>\\n";
}
function FriendlyErrorType($type)
{
switch($type)
{
case E_ERROR: // 1 //
return 'E_ERROR';
case E_WARNING: // 2 //
return 'E_WARNING';
case E_PARSE: // 4 //
return 'E_PARSE';
case E_NOTICE: // 8 //
return 'E_NOTICE';
case E_CORE_ERROR: // 16 //
return 'E_CORE_ERROR';

return 'E_USER_DEPRECATED';
}
return "";
}

-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 :-)

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

this would give you all the reported exception list of your configuration.
