how to start ob_start inside a class?

im doing a little reasearch about minimalizing the html from php. like

class themeing
{
    function render( $file, $folder )
    {
        if ( COMPRESS ) {
            // this is the problem
            ob_start('compressor'); 
        }

        $get = VIEWS . $folder . '/' . $file . '.phtml';

        if ( COMPRESS ) {
            ob_end_flush();
        }

        return $get;
    }

    function compressor($buffer)
    {
        $search = array(
            '/<!--(.|s)*?-->/',
            '/>[^S ]+/s',
            '/[^S ]+</s',
            '/(s)+/s'
        );
        $replace = array(
            '',
            '>',
            '<',
            '\1'
        );

        $buffer = preg_replace($search, $replace, $buffer);
        return $buffer;
    }
}

the problem is how do i call this ob_start(function) ? can we do like ob_start($this->compresssor()) ? ( ok i know it fails ) inside a class? anyone ??

Thanks for looking in.

Answer

ob_start(array($this,'compressor'))

PHP uses an array(instance,function) representation for representing member functions of classes as callable functions.
