For this example, let’s say you have a site you want to post data to so a newly trained employee is added to a mailing list.  In the older days of php, you could do this with http_post_params; however, this function is now deprecated.  Instead, you can use the curl method, or you can use some Zend libraries.

Since this is a post on using Zend, I think you know which one I chose to do.

The following example is a really simple one.  I’m just using a configuration file to hold my options and parameters to use for creating a curl request.  Then I have a script that reads the config  file, creates the request, sends the request, and then checks the response.

The Configuration File

; --configuration file /configFile/myConfig.ini

;connection info
 curl.mailingList.adapter = Zend_Http_Client_Adapter_Curl
 curl.mailingList.uri = ""

;authentication/post parameters
 curl.mailingList.postParameter.APIUSER = "admin_user"
 curl.mailingList.postParameter.APIPWD = 'some_password'

;configuration options
 curl.mailingList.options.curloptions[CURLOPT_RETURNTRANSFER] = true
 curl.mailingList.options.curloptions[CURLOPT_HEADER] = false
 curl.mailingList.options.curloptions[CURLOPT_ENCODING] = ""
 curl.mailingList.options.curloptions[CURLOPT_AUTOREFERER] = true
 curl.mailingList.options.curloptions[CURLOPT_CONNECTTIMEOUT] = 120
 curl.mailingList.options.curloptions[CURLOPT_TIMEOUT] = 120
 curl.mailingList.options.curloptions[CURLOPT_MAXREDIRS] = 10
 curl.mailingList.options.curloptions[CURLOPT_POST] = 1
 curl.mailingList.options.curloptions[CURLOPT_VERBOSE] = 1
 curl.mailingList.options.timeout = 120
 curl.mailingList.options.maxredirects = 10

Performing the Curl

To actually perform the curl, we will need to load the configuration file into our code and then prepare the curl to send.

 * Create a post request to add a new trainee to the mailing list
 * PHP Version 5
 * @created 10/12/2011
 * @updated 10/12/2011

 * Include the Zend_Loader class
require_once 'Zend/Loader.php';

//load the needed Zend libraries
Zend_Loader::loadClass('Zend_Config_Ini');  //for reading the configuration file

//read in the configuration file
$config = new Zend_Config_Ini('/configFile/myConfig.ini', 'production');

//setup our post params (subscribees is the name of the form field)
$postParam = array('subscribees' => '');

//try to create and send the curl
        //setup the curl connection
        $adapter = new Zend_Http_Client_Adapter_Curl();

        //instantiate the http client and add set the adapter
        $client = new Zend_Http_Client($config->curl->mailingList->uri);

        //add the post parameters from our config file (the authentication part)

        //add our post parameters to the request

        //perform the post, and get the response
        $response = $client->request(Zend_Http_Client::POST);

        //check the response for success
        if (strpos($response, "<h5>Successfully subscribed:</h5>") !== false) {

            echo "<p>Added {$fullName} to trainee email list successfully.</p>";

        } else if (strpos($response, "Already a member") !== false) {

            echo "<p>Already a member of the trainee email list";

        } else {

             echo "<p style='color: red;'>ERROR: Not added to the trainee email list</p>";
catch (Zend_Http_Client_Adapter_Curl_Exception $e)
    echo "<p style='color: red;'> ERROR: Failed to add the employee to the trainee email list.</p>";
catch (Zend_Http_Client_Exception $e)
     echo "<p style='color: red;'> ERROR: Failed to add the employee to the trainee email list.</p>";

As you can see, the script is not very complex. But it could be expanded to handle logging of errors and other functionality.
