This is because $a->b is a member not a method.
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.
