i love bofh solutions and have to agree with Seifried

in php you can do this by allow_url_fopen 0

allow_url_fopen "1" PHP_INI_SYSTEM
PHP_INI_ALL in PHP <= 4.3.4. Available since PHP 4.0.4.

this don't stop your clients from using functions like fsockopen and
socket_ so people that need to fetch remote data is still able use these
functions and handle a simple http get request manually

this is like open_basedir that doesn't affect (naturally)
exec/system/shell_exec/proc_/passthru/backtick functions

anyway filter the outgoing traffic != allow_url_fopen 0

also a transparent squid on the gateway of your web servers could be a
good idea to identify abuses
