Previously, i am using zend 1.x. I am able to autoload zend classes using the below code.
// autoload class from Zend Lib
require_once ABSPATH.'/classes/Zend/Loader/Autoloader.php';
$loader = Zend_Loader_Autoloader::getInstance();
try{
// database connection
$dbo = Zend_Db::factory('pdo_mysql', array(
'host' => DB_HOST,
'username' => DB_USER,
'password' => DB_PW,
'dbname' => DB_PREFIX.DB_NAME
));
$dbo->getConnection();
// save database adapter for easy usage in other classes
Zend_Db_Table::setDefaultAdapter($dbo);
Zend_Registry::set('db', $dbo);
}catch(Zend_Db_Adapter_Exception $e){
print $e;
//header("Location: http://www.google.com/error/");
}
I am upgrading to zend 2 as the classes might be better. May i know how do i autoload them?
If you are just using ZF2 as a standalone library without employing the full MVC framework, then autoloading is fairly straightforward:
Zend directory is on your php include_path.spl_autoload_registerThe following is essentially what Zend\Loader\StandardAutoloader::loadClass() does when functioning as a fallback autloader:
spl_autoload_register(function($class) {
$f = stream_resolve_include_path(str_replace('\\', '/', $class) . '.php');
if ($f !== false) {
return include $f;
}
return false;
});
This would use the PSR-1 autloading mechanism for all classes, not just the Zend classes.
Alternatively, you could just do the following:
require_once 'Zend/Loader/StandardAutoloader.php';
$autoloader = new Zend\Loader\StandardAutoloader(array(
'fallback_autoloader' => true,
));
$autoloader->register();
As above, this will apply PSR-1 autoloading to all classes. If you want this mechanism for the Zend classes only, then pass 'fallback_autoloader' => false.
I would Suggest you to study a skeleton App Provided by ZF2, I am not much aware About ZF1 but as far as i know ZF2 has its own mechanism of Auto Loading, as far as Auto Loading is concerned when you follow Skeleton Application you will notice that there is a Config\application.config.php this is the file where we load All the Modules etc. As a sample i will load my file below. As far as setting connections etc is concerned you will find them under them same directory tree i.e "Config\local or Config\Global".
<?php
return array(
// This should be an array of module namespaces used in the application.
'modules' => array(
'ZendDeveloperTools',
'DoctrineModule',
'DoctrineORMModule',
'Application',
'Administration',
'Account',
'Manufacturing',
'GridMain',
),
// These are various options for the listeners attached to the ModuleManager
'module_listener_options' => array(
'module_paths' => array(
'./module',
'./vendor',
),
'config_glob_paths' => array(
'config/autoload/{,*.}{global,local}.php',
),
),
);
You can also load the individual components through Composer and then you just need to include require 'vendor/autoload.php'; at the start of your execution script.
