Operating system: Solaris
PHP version: 5.2.5
PHP Bug Type: *Directory/Filesystem functions
Bug description: glob returns FALSE instead of empty array when no files
matched
Description:
------------
What I am reporting seems to me be the same as Bug #43461, but Jani and
Ilia took the problem to be as in Bug #43407 where a directory in the path
does not exist. Here we are in the current directory but simply cannot
match any files. The documentation clearly states that in such a case the
function will return an empty array.
Nevertheless, we turned safe_mode off to see what would happen, and glob
then returned an empty array as expected. However, we cannot run our web
server with safe mode off. I think this was working up until the latest
version 5.2.5. I can write everything with the opendir, readdir, etc.
functions even with safe_mode on, so I don't quite follow Ilia's logic
about bypassing safe_mode, but in any case, if the directory exists glob
should return an empty array when no files are matched whether safe_mode is
on or not. If not, the returned array from glob cannot be used (as it
often is) in other functions expecting an array argument, and many things
will break in a lot of existing code. If glob's behavior has indeed
changed, then it needs to be noted in the documentation.
Reproduce code:
---------------
glob("*.jpg");
Expected result:
----------------
empty array
Actual result:
--------------
boolean FALSE
