The following script doesn't work in PHP4 :

<?
class titi {
function toto() { echo "meuuh"; }

function  main() {
  $var = "\$this->toto";
  $var();
}
}
$titi = new titi;
$titi->main();
?>

Notice that it doesn't work in PHP3 either, so it is not a bug report, rather a feature request.

It doesn't make sense in PHP3, but if you intend to push OO features in PHP4, function pointers might be pretty useful.

They do, you're just using the wrong notation.  The function name
does not include $this - $this is only where the function is
searched.

This is the notation you should use:

$var = "toto";
$this->$var()
