In old apache 
1.3.26/php.4.0.6


if (file_exists("somefile.pdf")) unlink("somefile.pdf");
pdf_open_file($pdf, "somefile.pdf");

would check the current directory.
ie .. it will do these actions whereever documentroot happens to be.

now it does not do this anymore in Apache/2.0.42 (Unix) mod_ssl/2.0.42 OpenSSL/0.9.6b PHP/4.2.3 

in apache 2.0.42
getcwd() returns the current working directory <documentroot>

however if i do chdir (documentroot)
the first command 
if (file_exists("somefile.pdf")) unlink("somefile.pdf");
will work
but the 2nd
pdf_open_file($pdf, "somefile.pdf");
will not.

the workaround seems to be to work is to include the whole path
pdf_open_file($pdf, "$documentroot/somefile.pdf");

which appears to work .. is this a bug or a feature?

A smarter variant of the workaround is to use
file_exists(realpath('somefile.pdf'));
which works quite fine on Apache 2.0.40

on further examination it appears only 
pdf_open_file($pdf, "somefile.pdf"); 
does not work and must be substituted with
pdf_open_file($pdf, "$documentroot/somefile.pdf");

(or the smart example) 

i took the liberty of checking with pdf.c and it doesnt appear to be any different.

CVS Snapshot had no impact.
