Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. Because of this, we hope you add your comments
to the existing bug instead.
Thank you for your interest in PHP.

Filesystem function: file_exists() return value (PHP_VERSION='4.3.1',
PHP_OS='WIN32')
file_exists() returns TRUE if it is passed a null string or an
undefined variable.
e.g. file_exists(""); // returns TRUE
Previously it always returned FALSE (at least it did in PHP3).
Is that a bug or a change of definition? If so it is undocumented. The
rsult is also inconsistent with that returned by is_file() in this
case, as my example below demonstrates.
I note this is a similar report to apparently "bogus" #19934. Perhaps
this will convince you?
Example script:
As given in Manual\function.file-exists.html (modified to demonstrate
the above fault):
<?php
$filename = '';
print "<BR>file_exists: ";
if (file_exists($filename)) {
print "The file $filename exists";
} else {
print "The file $filename does not exist";
}
print "<BR>is_file: ";
if (is_file($filename)) {
print "The file $filename exists";
} else {
print "The file $filename does not exist";
}
?>
Result is:
file_exists: The file exists
is_file: The file does not exist
I also tried it with unset($filename) instead of a null string
assignment in the above, and get the same result.
