将PHP框架放在Linux主机上的位置

Question

I have a Linux (CentOS) host that hosts 5 websites of mine. There are two different PHP frameworks (Yii & Zend), each of my sites is based on one of them. Where would be an appropriate place to keep them, with what permissions? I though of two variants but I have doubts that any of them is the right thing to do.

In my projects, which reside in for example /home/example.com/public_html/index.php I would do require_once($pathToFrameworkInitFile)

Variant 1:

Under /usr/local/, user root with permissions 755:

/usr/local/frameworks/yii/yii-1.1.9/
/usr/local/frameworks/yii/yii-1.1.10/
/usr/local/frameworks/zend/zend-1.11.12/

Variant 2:

Under user frameworks with permissions 755: /home/frameworks/yii/yii-1.1.9/ /home/frameworks/yii/yii-1.1.10/ /home/frameworks/zend/zend-1.11.12/

Variant 3:

I hope that you might suggest something better.

As you suppose - I have full root access to the host and I'm managing both websites and host myself, so I'm looking for the best (or at least good enough) practice.

Answer 1

After reading more about the Unix FS Hierarchy Standard, I decided to put the frameworks in:

/opt/php-frameworks/yii-(version)
/opt/php-frameworks/zend-(version)

With permissions 755, under the root account. Most best practices say that the framework should be out of the docroot and /opt seems ideal for such libraries as php frameworks.
