Right. But in that case the script would be printing both 'false' and 'array'.
It prints only 'false'.
I have just added var_dump() at the end of the test case and now the output is:
false
bool(false)
BTW: I am using PHP 5.3.5 now.

"array() == false" is true because array is empty
try var_dump($glob) to be sure that glob does not return an array

Yeah, I meant that since I tested it under Apache first and that directory is
located in /srv/http, i.e. in the root directory of the server.
But you're right - for php being run from command line I should have used
relative path. Still, when I remove the leading slash and run
cd /srv/http; php test.php
the result is still false.
This is a contrived example anyway. Originally I have noticed it in a more
complex path.
If I do
touch /srv/http/phpMyAdmin/a.file
the script starts printing 'array'.

Are you sure you mean $glob = glob('/phpMyAdmin/*'); and not $glob =
glob('phpMyAdmin/*');? The sooner is an absolute path '/phpMyAdmin/', where the
2nd path is relative (to CWD).

Description:
------------
On my system the glob() returns false if there are no files matching the
pattern even though the documentation
(http://php.net/manual/en/function.glob.php) states that it should return an
empty array.
PHP version: 5.3.3
The only things I have changed in php.ini are open_basedir
(/srv/http/:/home/:/usr/share/webapps:/etc/webapps:/tmp/:/usr/share/pear/:/usr/share/symfony)
and enabling of several extensions (mcrypt, mysql, pdo, pdo_sqlite).
I've seen similar bugs reported and closed a few years ago: #29928
Test script:
---------------
<?php
// phpMyAdmin is an empty, existing directory located in Apache root
$glob = glob('/phpMyAdmin/*');
echo $glob == false ? "false\n" : "";
echo is_array($glob) ? "array\n" : "";
?>
Expected result:
----------------
glob() should return an empty array if no files match the pattern.
Actual result:
--------------
The script prints 'false' when run on my box (both under Apache 2.2.17 and with
php from command line).
