Method callbacks are performed with the syntax array( $object, 'method'); in your case you want to write

preg_replace_callback( '/{([A-Z_][A-Z0-9_]*)}/i', array( &$this, 'callmeback');, $text);

Btw, you missed the ' after callback( ...

I was using preg_replace with the '/F' parameter, and it
was working perfectly till v4.0.4pl1. Now it has been
substituted by preg_replace_callback.

Does preg_replace_callback work with class method as a callback function, too? If it does, how should it be
written?

I'm asking this because in each of these cases:

preg_replace_callback(/{([A-Z_][A-Z0-9_]*)}/i', $this->callmeback, $text);
preg_replace_callback(/{([A-Z_][A-Z0-9_]*)}/i', "$this->callmeback", $text);
preg_replace_callback(/{([A-Z_][A-Z0-9_]*)}/i', '$this->callmeback', $text);

I get a warning:

preg_replace_callback() requires argument 2, [...],
to be a valid callback

More: there is another drawback. With preg_replace + '/F' parameter I could also specify additional parameters in the command line. Now I can't.
