title: Send PHP Mail in intervals
body: <p>I'm working on a simple text messaging service for my high school's student council and my hosting service only allows 19 PHP mail messages to be sent per minute, so is there a way I can set an interval to only send 15 emails, wait a minute, send another 15, wait, and do so until all the mail is sent? Below is some of my code, all you'll probably need to see is the "foreach" section. </p>
  
  <pre><code>$subject =     ""; 
  $message =     "Hey, $first! $messageget";
  
  $header =     'From: Student Council&lt;email@email.net&gt;' . "\r\n" .
                 'Reply-To: email@email.net' . "\r\n" . 
                'X-Mailer: PHP/' . phpversion(); 
  
  
  foreach($to as $value) { 
  
      $result = mail($value, $subject, $message, $header); 
  
  
  
  } 
  </code></pre>
