Is there a way to trap PHP E_PARSE errors?  We want to show the user a
"pretty error page" (and notify our techs), rather than just showing
the user the raw Parsing error.

The default PHP error handler overrides any user defined handlers for
the E_PARSE error so this error type cannot be handled with a user
defined function.

Maybe there is a way to generate a script error instead so that Apache
can redirect when an E_PARSE error occurs?  Thanks!

It is impossible to catch an E_PARSE error.  The reason is that this
error means the PHP interpreter has choked on the code provided -
therefore there is no way it can find and run an error handler that
you have written in your PHP code.

The only thing you can do is disable the error message from being
reported, which I would not recommend - this would show the user a
blank page instead of an error message.

Sorry I can't be more help!
