 New Comment:

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation
better.

This is the case on some unices, and is actually in the
POSIX 1 standard:

In section 5.2.2.4: For each of the following conditions, if
the condition is detected, the getcwd() function shall
return a value of NULL and set errno to the corresponding
value:

    [EACCESS] Read or search permission was denied for a
    component of the pathname.

So I've documented this and the fact that the return value can be
false.

At least Linux, OpenBSD, AIX, Solaris and HP-UX implementations of
getcwd() should behave the same way.
(I didn't test it, just read the man pages I found with google :)

I have experienced on two servers, one Linux (unkown distro) server
running 4.3.1 and an other unkown UNIX (?) computer with the opposite
effect (the effect I was expecting myself). Could this be a OS specific
issue?

Anyways the documenation should be clarified.

>From "man getcwd":

RETURN VALUE
  NULL  on failure (for example, if the current directory    
  is not readable), with errno set accordingly,
  and buf on success.

And as PHP just wraps around this function, the behaviour is the same.

Description:
------------
If one of the parent directories of the current working directory
doesn't have the readable flag +r (while +x is still specified)
getcwd() return false, even though the current directory has full (or
at least readable & executale) access (the restrictive permissions
apply ONLY to the parent directory).

The possible return value of false isn't either mentioned in the
documenation.

Reproduce code:
---------------
mkdir one ; mkdir one/two ; mkdir one/two/three
echo "<?php echo gettype(getcwd()).'; '; echo getcwd() ? 'true' :
'false'; ?>" > one/sample.php
echo "<?php echo gettype(getcwd()).'; '; echo getcwd() ? 'true' :
'false'; ?>" > one/two/sample.php
echo "<?php echo gettype(getcwd()).'; '; echo getcwd() ? 'true' :
'false'; ?>" > one/two/three/sample.php
chmod 111 one ; chmod 755 one/two ; chmod 755 one/two/three
chmod 644 one/sample.php ; chmod 644 one/two/sample.php ; chmod 644
one/two/three/sample.php

Expected result:
----------------
one/sample.php:
string; true

one/two/sample.php:
string; true

one/two/three/sample.php:
string; true

Actual result:
--------------
one/sample.php:
string; true

one/two/sample.php:
boolean; false

one/two/three/sample.php:
boolean; false
