PHP "Hello World" code to get and put data in a datagroup on LTM

Hopefully this will post correctly in the forum.

Simple PHP datagroup GET function

// function dg_GET : get the current datagroup values
// inputs:
//      $host = BIG-IP hostname
//      $datagroup = datagroup name
//      $adminpass = formatted admin name and password (ex. admin:admin)
// output:
//      array of datagroup records
function dg_GET($host, $datagroup, $adminpass) {
    // build the request
    $service_url = 'https://' . $host . '/mgmt/tm/ltm/data-group/internal/' . $datagroup;
    $ch = curl_init($service_url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERPWD, $adminpass);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
    // execute the request
    $response = curl_exec($ch);
    // format/strip the resulting records array
    $array = json_decode($response, true);
    $dgarray = $array['records'];
    curl_close($ch);
    return $dgarray;
}

To use the dg_GET function:

$dg_get = dg_GET('10.80.0.103', 'testdg', 'admin:password');
print_r($dg_get);

Simple PHP datagroup PUT function

// function dg_PUT: add items to existing datagroup
// inputs:
//      $host = BIG-IP hostname
//      $datagroup = datagroup name
//      $adminpass = formatted admin name and password (ex. admin:admin)
//      $arraydata = array-formatted recordset to pass to datagroup
// output:
//      array of datagroup records
function dg_PUT($host, $datagroup, $adminpass, $arraydata) {
    // call dg_GET to get the existing values
    $current_values = dg_GET($host, $datagroup, $adminpass);
    // build the request
    $service_url = 'https://' . $host . '/mgmt/tm/ltm/data-group/internal/' . $datagroup;
    $ch = curl_init($service_url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERPWD, $adminpass);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
    // format the datagroup records
    if ($current_values != "") {
        // append existing values to datastring
        array_push($current_values, $arraydata);
        $jsonstring = json_encode($current_values);
    } else {
        $jsonstring = '[' . json_encode($arraydata) . ']';
    }
    //format the post payload
    $post = '{"name":"' . $datagroup . '","records":' . $jsonstring . '}';
    // execure the request
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($post))
    );  
    $response = curl_exec($ch);
    // format/strip the resulting records array
    $array = json_decode($response, true);
    $dgarray = $array['records'];
    curl_close($ch);
    return $dgarray;
}

To use the dg_PUT function

$test = array(
    "name" => "roger",
    "data" => "rabbit"
);
$dg_post = dg_PUT('10.80.0.103', 'testdg', 'admin:password', $test);
print_r($dg_post);

Notice that the PUT function relies on the GET function to fetch existing values. iControlREST does not have the ability to add to an existing datagroup, so the PUT function must first get the existing values and then replace the entire recordset with the new values. Also note that there is absolutely no error checking in this sample code.
