Not sure if this is a typo or the actual line, but changing delimiters
is not valid

Since php is running as the web server user, anything it creates is
owned by apache, and apache must have permissions to write where the
file is created.

Also, apache (the web server) must be able to access/execute in the
directory used.

You will need to make sure that the .conf file for apache/the app
( usually a file in /etc/httpd/conf.d/*.conf ) provides permissions to
write/execute in whatever directory you are using and that permissions
are otherwise restricted.

This also may be impacted by selinux if you have it in enforcing mode.
