Today I enabled the allow_url_include configuration option in PHP on Apache on ProgClub MemberNet. This allows me to include a source file directly from svn, e.g.:
require_once( 'https://www.progclub.org/svn/pcrepo/slib/trunk/src/uri.php' );
Today I discovered the user_agent php.ini configuration option. Basically it allows you to specify the user agent PHP uses when it sends HTTP requests for files. I was screen scraping some data from Wikipedia (processing URI schemes) and it was replying with a 403 error, presumably because they’ve banned the default PHP user agent. Anyway I just changed my user agent to a copy of my one from Firefox and things started working. Pretty handy option!
