I create a plugin for WordPress that requires two files to be exists in order to operate normaly.
The first file is defined as a file system path and the second file is defined as a URL.
Let's say the first file is that:
/home/my_site/public_html/some_folder/required_file.php
and the second file is that:
http://www.my_site.com/some_folder/required_url_file.php
Note that both files are not the same file into the file system. The required_file.php has other content than the required_url_file.php and they act absolutly diferent
Any idea on how to validate the existance of both files ?
