1.1.1. Verifying the PHP SDK

To verify you have correctly set up the PHP SDK and the underlying C SDK follow these steps:

Create a new file named test.php and place the following test code it:

<?php
    $cb = new Couchbase("127.0.0.1:8091", "username", "password", "default");
    $cb->set("a", 101);
    var_dump($cb->get("a"));
?>

Start your Couchbase Server. Note the ip address and port for Couchbase Server and any username and password.
If you need to, update the IP address, username and password in test.php with your Couchbase Server information.
Save the new script as test.php.
Run your test script:
```
shell> php test.php
```
Couchbase Server returns 101.

If you are using the PHP SDK on a Linux distribution such as Red Hat/CentOS, be aware that JSON encoding for PHP is by default not available to other extensions. As a result you will receive an error resolving the php_json_encode symbol. The solution is to edit the PHP configuration file as we described earlier to include the JSON extension and then the Couchbase extension. For instance, if your PHP config file is /etc/php.ini, add the following two lines to the file:

extension=/path/to/json.so
extension=/path/to/couchbase.so

The references to your JSON library and the PHP SDK need to be provided in this order.

Now you are ready to ready to develop with the PHP SDK and Couchbase Server 2.0. For more information about methods available in this SDK, see Couchbase Client Library: PHP 1.1. For learning more in general about developing application on Couchbase Server, see Couchbase Developer's Guide 2.0.
