## #42770 — Thomas Koch — 2009-01-22T09:58:12+00:00

There are already empty placeholders for this kind of informations in
the PHP documentation. These could be filled.

Sara's book is a good start, but it could be updated to wash out all
PHP4 stuff and put in new things developed since then.

Some more informations on memory management would be fine:
- How to deal with libraries that have there own memory management?
- Some workflows for debugging

What's best practice? I'm not that comfortable with copying stuff from
other extensions, since I don't know if I'm copying legacy stuff.

An example extension would round it up.

Best regards,
