One option that you might want to look at is: http://php.net/classkit Keep in mind the above is still in beta, but will allow you to add/remove/redefine methods of objects at runtime. iirc it works with php4 and php5. The other option would be to set a variable within a class that the method b() uses: class impl_a { var $_b; function setFunc($func, $params, $code) { $var = "_$func"; /* set up $this->varname */ $this->$var = create_function($params, $code); } function b() { $func = $this->_b; $func(); } } $a = new impl_a(); $a->setFunc('b', '', 'echo "hello world"'); $a->b(); Its Not very clean solution, but might work in you situation.
