如何包含Zend_DB类？

Question

I want to use the class Zend_Db (and other Zend classes later). However, after 5 hours I am still not able to access this class. Could someone please point me towards a solution? It would already be helpful to know which of the hundreds files in the Zend framework contains this class? Thanks a million in advance!

More details on my problem: I am receiving the following error message

Fatal error: Class 'Zend_Db' not found

upon doing the following:

1) Downloaded Zend 2.2.5 and moved it to my server at /home/www/Zend/library

2) Added following line to php.ini: include_path=".:/home/www/Zend/library"

3) Ran following index.php:

    require_once 'Zend/Loader/AutoloaderFactory.php';
    require_once 'Zend/Loader/StandardAutoloader.php';
    require_once 'Zend/Loader/SplAutoloader.php';
    $options = array(Zend_Db::AUTO_QUOTE_IDENTIFIERS => true);

    $db = new Zend_Db_Adapter_Pdo_Mysql(array(
        'host'     => MYSQL_HOST,
        'username' => MYSQL_BENUTZER,
        'password' => MYSQL_KENNWORT,
        'dbname'   => MYSQL_DATENBANK,
        'options' => $options
        ));`

Background: It's my first time using Zend. I am working on an Apache Server with PHP 5.3.21. I am using Zend 2.2.5

Answer 1

The code you've included was written for ZF1, but you have downloaded ZF2. The two are not compatible. You need to either change your code to work with ZF2, or download the latest version of ZF1.

Answer 2

If you really want to use Zend_DB, you can use the composer autoloader and setup a classmap. Define where the classmap should look and with ./composer.phar install you automagically generate a class-map in which composer will do the rest.

With ZF2 I presume you use composer, if not, use it. This website also contains the basics on how to use it:
