Executing the example above with:
php -n fetch.php
http://no2.php.net/get/php-5-LATEST.tar.bz2/from/this/mirror
php-latest.tar.bz2
will output something similar too:
Connected...
Mime-type: text/html; charset=utf-8
Being redirected to: http://no2.php.net/distributions/php-5.2.5.tar.bz2
Connected...
Filesize: 7773024
Mime-type: application/octet-stream
