我想包含 ZendXXX\Db.php

如何改变它

Answer 1

创建一个目录(比如'lib')，并将您的 Zend 目录放入其中。所以你的目录结构是这样的:

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

现在您应该将 lib 添加到包含路径中。编辑你的 index.php 文件:

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

现在您的包含路径中有您的库。你可以像这样包含所有 Zend 组件:

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

最好的方法是先包含 Zend_Loader 然后用它来加载类。这样做:

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

您还可以注册自动加载类。只需将这一行添加到您的代码之后:

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

现在您不需要包含文件来调用类。只是实例化你的类:

$session = new Zend_Session_Namespace('user');

不需要包含“Zend/Session/Namespace.php”。
