I'm not sure I get what you want to know but you can see the php version by either doing an "echo phpversion();" or by just calling phpinfo(); from your code. Both will contain the version number for the php that is running your code.

Thank you for your response. I need to set allow_url_fopen "on" and understand that I need to do that thru php5.ini. Can I set up a php5.ini file?

PHP always uses an INI file. Trick is to find out which one it is using. Just run a file with phpinfo(); in and the output will tell you the location of that file ("Loaded configuration file" in the first box).

-- or --

If you can access PHP from the command line and run it that way (I often write command line stuff with PHP) you can run the command: php --ini

It will show you all of the ini files that php is loading when it is initialized.
