I apologize - I also could not reproduce the bug in the simple test script 
I previously submitted - I was sure that that would reproduce it. But it 
did not match exactly what
was going on in my actual script.

The problem seems to only occur when two file_exists statements are used in 
a row and the
path argument used uses the same "slash style" each time.

See the attached script - it is commented so you can see the problem and it 
should work - I have tested this one. Thanks.

/*This is an example of an apparent bug using file_exists twice (tested on a win95 
system using
php 4.0.4 cgi version, omnihttpd). The second test of file_exists will report a false 
(that the file does exist when it doesn't) unless you use a unix style path as an 
argument to 
the first test, and a dos style as an argument to the second test, or vice-versa, i.e, 
will get a false positive on the second statement if you use the same path style both 
even though the first file_exist statement will evaluate properly.Also see comments 
below. */


echo "<html><body>\r\n";

//create test file
exec("dir > $file_name");
echo "File  $file_name created<br>";


/******First File_Exist Test *******
 This will always evaluate properly but the style of the argument used effects whether 
the second 
 file_exist test below works."


        echo "File $file_name deleted";

        } else {
        echo "Can't find $file_name - not deleting<br>";
/*****Second File_Exist Test ************************
 The file_exist statement below won't evaluate properly (giving a false positive) 
unless you 
 use unix style file name first, then dos style second, or dos style first, and unix 
style second. 
 Can't use them at same time - otherwise this second file_exist test will report that 
the file 
 does exist when it doesn't exist. 
 Test this for yourself by alternating the commented if statements in the first and 
second file
exist tests. The script as written will produce a false positive that the file does 

if(file_exists($file_name_dos)){                    //To fix, comment out this line, 
and remove the // on the above line OR you can do the same for the first file_exist 
test above

} else {
