Bootstrapping Zend Framework 1.x with composer namespaces

index.php

<?php
/**
 * Bootstrap the App in an annonymous function preserving global namespace.
 */
call_user_func(function(){
    // Define path to application directory
    defined('APPLICATION_PATH')
        || define('APPLICATION_PATH',
         realpath(dirname(__FILE__) . '/../application'));

    // Define application environment
    defined('APPLICATION_ENV')
        || define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ?
        getenv('APPLICATION_ENV') : 'production'));
    /* Use the namespaces in composer to create an include that that zend can
     * Safely.
     */
    $paths = array_merge(
        array(
            get_include_path(),
            realpath(APPLICATION_PATH . '/../library'),
        ),
        include dirname(APPLICATION_PATH) .
            '/vendor/composer/autoload_namespaces.php'
    );
    foreach ($paths as $key => $path) {
        if(is_array($path)){
            foreach ($path as $p){
                array_unshift($paths, $p);
            }
            unset($paths[$key]);
        }
    }
    set_include_path(implode(PATH_SEPARATOR, $paths));
    /** Zend_Application */
    require_once 'Zend/Application.php';

    require_once dirname(APPLICATION_PATH) . '/vendor/autoload.php';
    // Create application, bootstrap, and run
    $application = new Zend_Application(
        APPLICATION_ENV,
        APPLICATION_PATH . '/configs/application.ini'
    );
    $application->bootstrap()
                ->run();
});

Please migrate to vendor/composer/autoload_namespaces.php and vendor/autoload.php - the .composer dir is there only for BC these days and will be removed at some point.

@Seldaek thanks for the heads up on this I wasn't aware of the change, just found the discussion from a few days ago on the google group.
