Some parse errors are caught by assigned error handler, and some are not.

I use:

error_reporting(E_ALL);
set_error_handler('my_error_handler');

For example:

<?php
i_am_some_parse_error
?>

is caught by error handler, and:

<?php
i_am_some_parse_error = 1;
?>

is not caught and displays: "Parse error: parse error in ... on line ...".

The first one is a runtime warning (Use of undefined constant ...) and not an parser error.

If the first one is not an parse error, why do I see "Parse error: parse error in ... on line ..." when I run the code without calling set_error_handler()? Are there any parse errors that are caught by an error handler?

It's unclear to me how you can reproduce a parser error:

$ ~/php/4.1.1/bin/php -q
<?
error_reporting(E_ALL);
i_am_some_parse_error
?>
<br>
<b>Warning</b>:  Use of undefined constant i_am_some_parse_error - assumed 'i_am_some_parse_error' in <b>-</b> on line <b>4</b><br>

I tested both 4.1.1 and CVS cgi. Where you using the CLI version?

And suppose i have the following main.php file:

<?php
function my_handler(...)
{ /* ... */ }
error_reporting(E_ALL);
set_error_handler('my_handler');
include('file_with_errors.php');
?>

and the file_with_errors.php contains some parse errors. Am I right, that there is no way to handle errors from file_with_errors.php?

oh well:

from the php docs: Note: The following error types cannot be handled with a user defined function: E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_ERROR and E_COMPILE_WARNING.
