I would roll through the globals checking if your exclusion variables are there and creating a temp. array, and after that replace $GLOBALS with the temp.

PHP Code:

function exclude_globals($exclude = NULL){
    
    //default exclusions
    $default_excludes = array("_POST","_GET");
    
    //roll through $GLOBALS
    $GLOBALS_temp=array();
    foreach($GLOBALS as $GLOBALS_name=>$GLOBALS_content){
        
        //check if vars are in global
        if (!(in_array($GLOBALS_name,$exclude) || in_array($GLOBALS_name,$default_excludes)) ){
            
            //assign to temp array
            $GLOBALS_temp[$GLOBALS_name]=$GLOBALS_content;
        }
        
    //replace globals with temp array
    $GLOBALS = $GLOBALS_temp;
    }
    
}

//call the function
exclude_globals(array("_FILES"));

//dump GLOBALS
echo("<h2>glob</h2>");
echo("<pre>");
print_r($GLOBALS);
echo("</pre>"); 


That takes away those variables from $GLOBALS but I'm not sure if that's exactly what you want
