[PHP] Relative Paths and file_exists() - Solaris

[James Nikolich]

Hello;
 
I'm using PHP 4.2.3 on a Solaris 2.8 (Sparc) system.
 
I've been having some difficulties getting PHP-Nuke 6.0 to work for me.
I eventually narrowed the problem down to incorrect results from calls
to file_exists().  It seems that file_exists() is having trouble finding
an existing file within a subdirectory of the current directory -- IF I
use relative pathnames.  If I use absolute pathnames (specifically by
prepending the results of getpwd() as stored in a variable), then things
work fine - but clearly this shouldn't be necessary.
 
I've written a sample PHP script to illustrate the problem I'm having.
Below it can be found the output of having executed this script.  (You
can see it for yourself @ http://wireless.pleiades.com/jim.php).  As you
can see, only the third test works - and that's the one with $CurrentDir
prepended to the $targetfile...
 
This is probably a "doh!" kind of problem, but it's got me stumped.  Any
help would be appreciated.
 
Thanks,
 
Jim

if ( file_exists( "$targetfile" ) ) {              
    echo "- Found it.<br>";
} else {    
    echo "- Not found.<br>";

    echo "- Found it.<br>";
