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.
Errors and LoggingValueConstantDescriptionNote1E_ERROR

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.
2E_WARNING

could indicate an error, but could also happen in the normal course of
running a script.

E_ERROR, except it is generated by the core of PHP.
32E_CORE_WARNING

This is like an E_WARNING, except it is generated
by the core of PHP.
64E_COMPILE_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.

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;.
