在没有骨架的应用程序中包含ZEND框架2.3

Question

There is a lot on the web about including ZEND, but I still don't get how to simply use it (without a skeleton) (In this case I only want to use Zend\Dom\Query)

I would like to:
1) Simply include the complete ZEND 2.3 library in a single application
or
2) Include a single ZEND 2.3 module

I'm using NGINX, but actually I just want to include it via PHP. Any hints, tips and or links?

What I did was:

include('./library/Zend/Dom/Query.php');
$c = curl_init($u);
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
$html = curl_exec($c);  
$dom = new Zend\Dom\Query($html);
$results = $dom->execute('.foo .bar a');
...

Error is: Fatal error: Class 'Zend_Dom_Query' not found in /SOMEDIR/myfile.php on line 12

A simple way to include it via PHP is :

1. Make sure that the Zend directory is on your php include_path. Assuming Zend directory is in the library folder you'll have something like this in your index.php file:

$path= array();
$path[] = '.';
$path[] = './../library';
$path[] = get_include_path();
$path= implode(PATH_SEPARATOR,$path);
set_include_path($path);

2. Now just include Zend/Loader/StandardAutoloader.php first and then use it to load other classes. You can do this :

require_once 'Zend/Loader/StandardAutoloader.php';
$autoloader = new Zend\Loader\StandardAutoloader(array(
'fallback_autoloader' => true,
 ));
$autoloader->register();

With the $autoloader->register(), you don't need to include files each time you want to call classes. You have just to instanciate your classes :

$dom = new Zend\Dom\Query($html);
