 [2000-04-25 12:56 UTC] pete at byways dot org 
When running PHP 4.0 latest CVS compiled as a Roxen module under Roxen 2.0.46, using the "exit" statement in a PHP script causes the web server to return an empty page ("Document contains no data").

PHP is configured using:

./configure --with-roxen=/usr/local/roxen/server --enable-roxen-zts --with-gettext=no --with-pgsql --without-mysql --enable-track-vars=yes --with-zlib --with-jpeg-dir=/usr --with-tiff-dir=/usr --with-session=/tmp --enable-trans-sid --with-pdflib=/usr/local

Here is a Pike backtrace of a request for a script that contains the exit statement, using the "Resolve Path" feature in Roxen Administration.  Execution seems to stop inside the PHPScript::run() method in php4.pike, at the line:

mid->my_fd->set_close_callback(done);


Roxen version: Roxen/2.0.46
Pike version: Pike v7.0 release 38
Requested URL: /standard/actions/index.html

Error: Indexing the NULL value.
RXML frame backtrace:

Have you tried using more recent version of php4?
Like php4.0.2 ?

Still a problem using PHP 4.0.2 compiled as a Roxen module with Roxen 2.0.74 and Pike 7.0.80.
 [2000-12-18 11:23 UTC] sniper@php.net 
Does this happen with latest snapshot from http://snaps.php.net/ ??
