PHP: Failed to open required file that exists

Question

I am trying to include the Zend_Service_Amazon_S3 file by using

require_once 'Zend/Service/Amazon/S3.php';

I have also included in the include path the directory where the entire Zend library is located, AND the installation is inside Zend Server CE (which includes the Zend Framework by default). However, no matter what I try, I only get the following for my troubles:

Fatal error: require_once() [http://php.net/function.require]: Failed opening required 'Zend/Server/Amazon/S3.php' (include_path='/usr/local/zend/apache2/htdocs:/usr/local/zend/apache2/htdocs/app/:.:/usr/local/zend/share/ZendFramework/library:/usr/local/zend/share/pear:/usr/local/zend/apache2/htdocs/app/vendors') in /usr/local/zend/apache2/htdocs/app/models/item.php on line 3

The Zend/Service/Amazon/S3.php is located under the paths:

• /usr/local/zend/share/ZendFramework/library
• /usr/local/zend/apache2/htdocs/app/vendors

Answer 1

Could it be the process that is running PHP does not have the required rights to read the file? Don't forget that a directory needs to be executable in order for a process to change to that directory (i.e. see the contents of its subfolders.)

Answer 2

Your error message says Zend/Server/Amazon/S3.php - Shouldn't it be Zend/Service/Amazon/S3.php?
