PHP Examples (Rest API)

PHP

An API library for performing basic operations. This requires the curl and pecl_http PHP extensions:

<?php

 * Needs PHP's curl and pecl_http extensions.
 *
 * All results are returned as an HttpMessage object.

A simple GET:

<?php

    'text/xml');

echo  $response->getResponseCode() . "\r\n" .
      $response->getHeader("x-error-message") . "\r\n" .

?>

A simple POST:

<?php
header('Content-Type:  text/plain');
require_once 'ApiServer.php';

$client = new  ApiServer();

$fields  = Array(
    'serviceType' => 'exchange',
    'exchangeMaxNumMailboxes' => '4');

echo  $response->getResponseCode() . "\r\n" .

A simple PUT:

<?php

echo  $response->getResponseCode() . "\r\n" .
      $response->getHeader("x-error-message") . "\r\n" .

A get with paging:

<?php

$client = new ApiServer();
$format = 'application/json';
$domain = 'apiPagingTest.com';

// Get mailboxes. page size defaults to 50.

$body = $response->getBody();
$result = json_decode($response->getBody());
echo $body . "\n";

// check results
$totalSize = $result->{"total"};
$resultSize = $result->{"size"};

// If there are more results, read the rest.
if($totalSize > $resultSize)
{
    // start at last read index and set page size
    $offset = $resultSize;
    $pageSize = 50;

    // read up to the next 50
    $url = '/customers/me/domains/' . $domain . '/ex/mailboxes?size='
