Operating system: Linux and varient
PHP version: 5CVS-2007-09-12 (snap)
PHP Bug Type: Filesystem function related
Bug description: Inconsistent behavior file_exists() & is_file() functions
Description:
------------
Inconsistent behaviour of file_exists() & is_file() functions when given
filename end with a trailing slash
The functions: file_exists(), is_file() return inconsistent value on
different OS when given
filename/path end with a trailing slash (/). On RHEL 5 and Windows XP that
i have, it retuns false, which is expected.
There have been some fixes done relating to this to get the consistent
behavior( match Windows with
Linux behavior on handling on trailing slash, Defect #42027) but I have
noticed that on different platform( linux and varient )
the output differ.
I think, this is something to do with the way realpath work on different
OS.
Following are the testcases that continue to fail because of this on few
linux and other Os but not on all(I have been watching the PHP-QA list and
seen these failures):
1) is_file_variation4.phpt
2) rename_variation.phpt
Reproduce code:
---------------
<?php
fclose( fopen("test.tmp") );
var_dump( is_file("test.tmp/") );
var_dump( file_exists("test.tmp/") );
unlink("test.tmp");
?>
Expected result:
----------------
bool(false)
bool(false)
Actual result:
--------------
Actual output ( on some of Linux and other OS, excluding Windows ):
-------------------------------------------------------------------
bool(true)
bool(true)
