Nope, that is incorrect. A PHP extension you load with extension=, a
Zend extension can hook into a bit more of the core of PHP and is loaded
with one of the zend_extension*= variants. That you need to use
zend_extension= is also described in the Xdebug documentation:
http://xdebug.org/install.php

The line in the menu says:
 Profiling: Xdebug 1, Xdebug 2

Click on the 'Xdebug 2' link and read that page.

The documentation says:
"Functions marked with [1] in the following index are only available in
Xdebug 1.3 and all functions marked with [2] are only available in
Xdebug 2.x."

Note the words "following index". And obviously, when there is "Xdebug
2" next to a function name, it won't work with Xdebug 1.3.

And next time, please send mail to the xdebug-general mailinglist, there
might be other people who can answer your questions or find them useful.
