I use the following set up:

  • PHP Version 5.2.17
  • Apache/2
  • Zend Optimizer v3.3.3
  • Drupal 7.8

As far as I read other articles and questions, Zend Optimizer doesn't do any good neither for PHP5 nor for D7.

I would like to use APC as PHP cache but APC is not compatible with Zend Optimizer.

Can I disable Zend Optimizer for selected subdomains ?

Example:

  • sub1.example.com redirects to an app that requires Zend Optimizer
  • sub2.example.com redirects to a Drupal app that doesn't require Zend Optimizer (I would like to disable Zend Optimizer for this subdomain)

Webhosting talk seems to think you may be able to use the php_value flag in your .htaccess (or VirtualHost def) in order to selectivly disable it in certain hosts:

php_value zend_optimizer.optimization_level = 0

  • Thank you, I tried this on one subdomain and included php_value in my .htaccess but it didn't help disable Zend Optimizer I am afraid. – LLub Sep 21 '11 at 17:40
  • I checked this again and used this php_value in php.ini instead of .htaccess then after httpd -k restart it disabled all Zend Optimizer optimization passes but this was for the whole server not for one subdomain. I am looking further for a solution. – LLub Sep 21 '11 at 18:16
  • I've tried it again in my .htaccess but without success. What should be done in order to enable setting php_value in .htaccess ? – LLub Sep 21 '11 at 20:17
  • Instead of putting it in your .htaccess, try php_admin_value in your virtual host definition. Some settings are restricted to where they can be set from; the php/zend documentation leaves a bit to be desired on this front, unfortunately! – Kirrus Sep 21 '11 at 22:23
