In short, PHP isn't recognizing a folder I have that is a mount point to a CIFS share.
Environment / Background information:
PHP 5.3.3 on Apache/2.2.15 (centOS) 2.6.32-431.5.1.el6.i686.
SElinux disabled; firewall off during testing.
Website document root is "/var/www/html" Within this directory I have a
folder called "projects", which is a mount point to a CIFS share on a
Windows 2003 server. It is mounted via fstab entry:
//WIN01/Projects /var/www/html/projects cifs rw,domain=XXX,credentials=/etc/samba/auth.support,uid=48,gid=48 0 0
(my UID 48 = apache)
So far this works as expected -- the projects folder is mounted by the
Windows user identified in the credentials file (I've verified this on
the Windows server) but appears to be owned by apache.apache. If I do this:
#su - apache -s/bin/bash
..I can browse to the /var/www/html/projects folder and its sub-folders
and add / edit files as expected.
When mounted, the /var/www/html/projects contains many levels of subfolders,
for example project_1, project_2, etc.
In addition to the projects folder, the website has a number of other "normal"
folders: test_1, test_2.
Finally, the PHP configuration file has this setting defined:
php_admin_value open_basedir "/var/www/html/:/var/www/html/projects/:/tmp/"
..although I've also tried:
php_admin_value open_basedir none
The Problem:
The web application needs to read and create files in the projects folder, but
PHP doesn't recognize the projects folder as folder! I suspect a
permissions problem of some sort, but I can't figure our where. I see nothing
in the HTTPD error logs. Also, I did have this same code working on an older server
[PHP 5.3.28 Apache/2.2.3 (CentOS) 2.6.18-371.4.1.el5 ]-- the
trouble started when I set the project up on the newer CentOS system.
Here's some test code that shows the problem:
$dirs = glob("$pat", GLOB_ONLYDIR );
if ( is_array($dirs) ) {
foreach ( $dirs as $dirname ) {
echo "Folder -> $dirname <br />\n";
}
}
Output:
Folder -> test_1
Folder -> test_2
(note -- no folder 'projects'!)
Tried the following:
echo "projects " . ( is_dir('projects') ? 'is' : 'is not' ) . " a directory<br />\n";
echo "projects " . ( is_file('projects') ? 'is' : 'is not' ) . " a file<br />\n";
Output:
projects is not a directory
projects is not a file
echo "test_1 " . ( is_dir('test_1') ? 'is' : 'is not' ) . " a directory<br />\n";
echo "test_1 " . ( is_file('test_') ? 'is' : 'is not' ) . " a file<br />\n";
test_1 is a directory
test_1 is not a file
