apache - Why can the same user make a directory on the command line but not via the webserver? -

i running apache on centos , in /etc/httpd/conf/httpd.conf file user , group both my-username

$ cat /etc/httpd/conf/httpd.conf|grep '^user' user my-username $ cat /etc/httpd/conf/httpd.conf|grep '^group' group my-username 

when run my-username on command line can create directory, not via call webserver.

$ cat test.php <?php  mkdir(dirname(__file__) . '/made-by-the-webserver', 0755); $err = error_get_last(); $user = exec('whoami'); echo 'whie attempting create directory, got ' . $err['message'] . ' running ' . $user;  $ curl mysite.local/test.php whie attempting create directory, got mkdir(): permission denied running my-username  $ whoami my-username  $ mkdir made-on-the-command-line  $ ls -lah|grep made  drwxrwxr-x.  2 my-username my-username 4.0k dec 16 14:51 made-on-the-command-line  $ php test.php  whie attempting create directory, got   running my-username  $ ls -lah|grep made  drwxr-xr-x.  2 my-username my-username 4.0k dec 16 14:52 made-by-the-webserver drwxrwxr-x.  2 my-username my-username 4.0k dec 16 14:51 made-on-the-command-line 

i expect that, because apache running user my-username, , my-username allowed create directories on command line, allowed create directories during call apache.

any in debugging appreciated, thanks!

almost due selinux. perhaps httpd_sys_script_rw_t property on parent directory needed?
