[PHP-DEV] PHP 4.0 Bug #3940: Virtual changes current directory - php4RC1!! From: rwidmer <email protected>

From: rwidmer <email protected>
Operating system: Red Hat Linux 5.2
PHP version: 4.0 Beta 4 Patch Level 1
PHP Bug Type: Misbehaving function
Bug description: Virtual changes current directory - php4RC1!!

If the file executed by virtual() is in a different
directory, the current directory is changed to the directory containing the virtual() file.

See it for yourself at:

   http://ns2.developersdesk.com/virtual/test.php3

Download a copy of the files in a tarball at:

   http://ns2.developersdesk.com/virtual/virtualtest.tar.gz

Untar this file in a directory that is document root. It will create a directory virtual and two files virtual.html and virtual.inc.

Here are the contents:

/virtual.html
----------------------------------------
Hello from the virtual.html file in document root
----------------------------------------

/virtual.inc
----------------------------------------
hello from the virtual.inc file in document root
----------------------------------------

/virtual/firstvirtual.html
----------------------------------------
hello from the first virtual.inc in the subdirectory
----------------------------------------

/virtual/virtual.html
----------------------------------------
hello from virtual.html in the subdirectory<BR>
----------------------------------------

/virtual/virtual.inc
----------------------------------------
hello from virtual.inc in the subdirectory
----------------------------------------

/virtual/test/php3
----------------------------------------
OK, lets try calling the include file, you should get the one in the subdirectory.
<BR><BR>
<? include( 'virtual.inc' ) ?>
<BR><BR>
Now lets call the virtual.html in the root directory and see what happens
<BR><BR>
<? virtual( '/virtual.html' ) ?>
<BR><BR>
Finally lets see what happens when we call the include file again.
<BR><BR>
<? include( 'virtual.inc' ) ?>
<BR><BR>
Oops, it looks like virtual() changed the current directory and did not change it back...
<BR><BR>
<? phpinfo() ?>
----------------------------------------

The current directory ./ will have to be in your include path for this
to work.

My system is:
Apache 1.3.12
mod_SSL 2.6.2
openssl 0.9.5
