Does eval() create a seperate parsing instance? to clear up the question are any variables function and classes not available within the eval() function? the reason I ask is because out of curiosity I created this...

PHP Code:


			
public function __call($funcName,$args)

        {

            $classArr = array(

                    'm_' => 'member',

                    't_' => 'template',

                    'f_' => 'file',

                    'u_' => 'upload',

                    'd_' => 'mysql'

                );

            $class = substr($funcName,0,2);

            $func = str_replace($class,'',$funcName);

            $func = preg_replace('$\\((.*?)\\)$','',$func);

            $order = $classArr[$class];

            if(!empty($order))

            {

                for($i=0;$i < func_num_args();++$i)

                {

                    $argList .= func_get_arg($i) . ',';

                }

                

                $c = substr($argList,strlen($argList) -1,1);

                if($c == ',')

                {

                    $argList = substr($argList,0,strlen($argList) -1);

                }

                $string = sprintf('$this->%s->%s(%s);',$order,$func,'o');

                echo $string;

                ob_start();

                eval($string);

                $ret = ob_get_clean();

                return $ret;

            }

        }
