I wrote a hopefully generic class in PHP to proxy CGI scripts. The idea being that sometimes one wants to get the output of a CGI script and do various things with it before displaying it. In my particular case, wrap CVSWeb so the output can be put into a HTML DIV.

The code is published on github as PHPGatewayInterface.

Returning Multiple Values

$error, $hash = function_a( ... );
if ( $error ) { error(); }    // never runs

Correction:

($error, $hash) = function_a( ... );
if ( $error ) { error(); }    // runs on error
