Description:
------------
I know that the include_path should contain forward slashes, but PHP 5.2.x still accepted backslashes in path.

If you use a backslash in your path, the next character is interpreted as an metachar (\trunk is interpreted as \t => tab).

Reproduce code:
---------------
include_path = ".;C:\ckl\dev\lang\php\lib\trunk"

Expected result:
----------------
echo get_include_path() => .;C:\ckl\dev\lang\php\lib\trunk

Actual result:
--------------
echo get_include_path() => .;C:\ckl\dev\lang\php\lib      runk

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

\t is still a special-character: the tab. Just like \r is a Carriage-Return and \n is a newline. It has always been this way, and is completely expected. These characters simply need to be escaped in double-quoted strings:
".;C:\\ckl\\dev\\lang\\php\\lib\\trunk"

Or don't use double quotes.

As I already mentioned in my initial post, I know that backslashes shouldn't be used - but this was possible till 5.2.6. Is that a bug in 5.2.6 that backslashes are *not* interpreted as a beginning for a coming meta character?

To summarize:
PHP 5.2.6:
include_path = ".;C:\ckl\dev\lang\php\lib\trunk"
get_include_path = ".;C:\ckl\dev\lang\php\lib\trunk"
( WRONG )

PHP 
include_path = ".;C:\ckl\dev\lang\php\lib\trunk"
get_include_path = ".;C:\ckl\dev\lang\php\lib    runk"
( RIGHT )

Conclusion: include_path in 5.2.6 is not parsed correctly.
Please change the version info of this bug if you agree with me.
