php text to speech with google api

// Convert Words (text) to Speech (MP3)
// ------------------------------------
$word=$_POST['word'];
// Google Translate API cannot handle strings > 100 characters
$word = substr($word, 0, 100);

// Replace the non-alphanumeric characters
// The spaces in the sentence are replaced with the Plus symbol
$word = urlencode($word);

// If the MP3 file exists, do not create a new request
// create curl resource
$ch = curl_init();

// set url
curl_setopt($ch, CURLOPT_URL, 'http://translate.google.com/translate_tts?ie=UTF-8&tl=en&q='.$word);

//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// $output contains the mp3 file
$mp3 = curl_exec($ch);

// close curl resource to free up system resources
curl_close($ch);

file_put_contents('temp/'.$word.'.mp3', $mp3);

PS: this code no longer works as google added captcha code

$message = Swift_Message::newInstance('Your subject');
$message
  ->setTo(array(
    'user1@example.org',
    'user2@example.org' => 'User Two',
    'user3@exmaple.org' => 'Another User Name'
  ))
  ->setFrom(array('your@address.com' => 'Your Name'))
  ->attach(Swift_Attachment::fromPath('/path/to/doc1.pdf'))
  ->attach(Swift_Attachment::fromPath('/path/to/doc2.pdf'))
  ->setBody(
    $message->embed(Swift_Image::fromPath('/path/to/image.jpg')) . '" />',
    'text/html'
  )
  ->addPart('This is the alternative part', 'text/plain')
  ;
if ($mailer->send($message))
{
  echo "Message sent!";
}
else
{
  echo "Message could not be sent.";
}
