What is no-debug-non-zts-20090626?

Question

In php.ini I have:

extension_dir = "/usr/lib/php/extensions"

However, running php-config gives:

--extension-dir  [/usr/lib/php/extensions/no-debug-non-zts-20090626]

This directory does not exist, and I could not find any information about it on the Web.

Can anyone shed some light on this strange directory?

Answer 1

It's an extension directory for PHP, named after some factors that influence extension compatibility: thread safety (non-zts), debug (no-debug), and engine version (20090626).

I recommend against changing the path. If it doesn't exist, create it, and put your extensions there. It's also where PECL will install extensions.
