How to modify opcache.interned_strings_buffer from .htaccess with php_value

Question

I'd like to modify opcache.interned_strings_buffer to 12 via .htaccess file

I've added the following block to .htaccess :

php_value opcache.interned_strings_buffer 12
php_value max_execution_time 180
php_value max_input_vars 1760

However only max_execution_time and max_input_vars changed.

I verified that values changed by inspecting phpinfo() output.

How to change opcache.interned_strings_buffer via .htaccess ?

Answer 1

According to documentation, most opcache directives are PHP_INI_SYSTEM so they should be changeable on httpd.conf or .htaccess. But opcache is a zend extension and value cannot be updated via .htaccess. I guess this is the problem.
