i want to include ZendXXX\Db.php

how to change it

回答1:

create a directory (say 'lib'), and put your Zend directory in it. so your directory structure looks like this:

- application
- lib
  |- Zend
- wwwroot
  |- index.php

now you should add lib to your include path. edit your index.php file:

$includePath = array();
$includePath[] = '.';
$includePath[] = './../application';
$includePath[] = './../lib';
$includePath[] = get_include_path();
$includePath = implode(PATH_SEPARATOR,$includePath);
set_include_path($includePath);

now you have your lib in your include path. you can include all Zend components like this:

include 'Zend/Loader.php';
require_once 'Zend/Db.php';

the best way is too include Zend_Loader first and then use it to load classes. do this:

require_once 'Zend/Loader.php';
Zend_Loader::loadClass('Zend_Db');

you can also register to autoload classes. just add this line to your code after all those before:

Zend_Loader::registerAutoLoad('Zend_Loader',true);

now you do not need to include files to call classes. just instanciate your classes:

$session = new Zend_Session_Namespace('user');

there is no need to include 'Zend/Session/Namespace.php'.

回答2:

Use set_include_path(). See PHP.net documentation

Example:

 set_include_path(get_include_path() . PATH_SEPARATOR . '/path/to/Zend');

回答3:

I usually store the framework files under a "library" folder:

• application
• public_html
• library
  • Zend
  • Common
  • etc....

and then in my bootstrap file, or front controller, I add that "library" folder to the include path:

set_include_path(get_include_path() . PATH_SEPARATOR . '../library');

回答4:

The reason the other suggestions say anything about doing that, is because it's a bad move - in other words, you're doing it wrong.

You can create a subdirectory and name it Zendxxx, but then you have to add that to your include_path, and change it, whenever you put a newly named version up.

I'd hazard a guess, and say that you don't have a good way to test the website (so you want to lock it to a particular version of ZF), and further, that you aren't using revision control, so you want all the previous versions of code in the site-directory to be able to go back to, if you find a problem when you change the live-running code directly on the server.

回答5:

project without library And including library from one location
project C:\xampp\htdocs\my\application
library C:\xampp\Zend\library

make changes in index.php

// Ensure library/ is on include_path
set_include_path(implode(PATH_SEPARATOR,  
           array(realpath(APPLICATION_PATH.'/../../../Zend/library'),get_include_path(),)));
