Whether require and use are similiar in php?

Question

use RingCentral\SDK;

or

require('/home/developer/workspace/ringcentral/demo/SDK.php');

Instead of using 'use' - php 5.6 command ,it is better to use require - php 5.3 ?

SDK class file contains following code

class SDK
{

const VERSION = '0.5.0';

/** @var Platform */
protected $platform;

/** @var Context */
protected $context;

public function __construct($appKey, $appSecret, $server)
{

    $this->context = new Context();

    $this->platform = new Platform($this->context, $appKey, $appSecret, $server);

}

public function getPlatform()
{
    return $this->platform;
}

public function getSubscription()
{
    return new Subscription($this->context, $this->platform);
}

public function getContext()
{
    return $this->context;
}

}

require() loads a script. The use command is to help with namespacing. See http://php.net/manual/en/language.namespaces.basics.php — RyanNerd, Aug 31 '15 at 05:06
I m working in PHP 5.3 ,so i could not use 'use' . can u say the alternative for 'use'? — Ramkumar P, Aug 31 '15 at 05:09
You can't use `use` in `PHP 5.3`. Because this feature is added in `PHP 5.4` — Indrasinh Bihola, Aug 31 '15 at 05:13

You have to require an autoloader to allow SPL autoload to resolve use statements:

// if you use Composer
require('vendor/autoload.php');
// or just require a PHAR
require('path-to-sdk/ringcentral.phar');

use RingCentral\SDK\SDK;

$sdk = new SDK(...);

You actually may omit use statement and use fully-qualified class name:

$sdk = new RingCentral\SDK\SDK(...);

require() is used to require another file while use is used to use a class from another namespace, so those both commands are totally different and not comparable.

In your case you will need to use require() unless you are using any kind of autoloading like composer to make the class available in your file.
