<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Use the Chilkat Email API to create or load an email.
$email = new CkEmail();

// The From name/address don't need to be specified. 
// GMail will automatically use your Gmail address if the following 2 lines are omitted.
$email->put_FromName('My Name');
$email->put_FromAddress('my_account_name@gmail.com');

$email->AddTo('John Smith','somebody@somewhere.com');
// To add more recipients, make additional calls to AddTo or AddCC, one per recipient...

$email->put_Subject('This is a test GMail email created using Chilkat.');
$email->put_Charset('utf-8');
$email->AddPlainTextAlternativeBody('This is a test');

// Create an HTML email body with an embedded image.

$sbHtml->Append('<html><body>This is a <b>test</b><br><img src=\'cid:STARFISH_CID\'/></body></html>');

// Add some attachments..

}

// OK.. we now have an HTML email with 2 attachments..
$sbMime = new CkStringBuilder();
$email->GetMimeSb($sbMime);

// Send the email.  (GMail has a 5MB limit on the total email size.)
$http = new CkHttp();

}

// A status code of 200 indicates success.

// The response body contains JSON.
// Use the online tool at Generate JSON Parsing Code
// to generate JSON parsing code.

// A sample successful JSON response:

// {
//  "id": "166f0d4ac39e50bf",
//  "threadId": "166f0d4ac39e50bf",
//  "labelIds": [
//   "SENT"
//  ]
