empty php.ini

[dreamfox]

Hello,

I have DA on freebsd 6.1
I installed zend optimizer.

Now 3 months later i need to increase the max_memory limit

When i do a locate php.ini i get this:
-bash-2.05b# locate php.ini
/usr/local/Zend/etc/php.ini
/usr/local/directadmin/customapache/php-4.4.2/php.ini-dist
/usr/local/directadmin/customapache/php-4.4.2/php.ini-recommended
/usr/local/lib/php.ini
/usr/local/lib/php.ini-zend_optimizer.bak

Wen i take a look at the files:
/usr/local/Zend/etc/php.ini
/usr/local/lib/php.ini

I see the same things:

[Zend]
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.0.0
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.0.0
zend_optimizer.version=3.0.0
zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so

Thats all

Where can i find the value:
memory_limit in php.ini

?
