In the code below. I have a function named notification(). While the condition is true I only what to call it once. I have set_time_limit(1) set to 1, but I continue to get multiple emails. The echo statement needs to keep working indefinitely, but the function should only be called once. How can I accomplish this?


<div style="text-align: center">

require '/usr/share/php/Mail.php';

function notification (){
$mail = new Mail();

$headers = array(
      'From' => 'noreply@localhost',
      'Subject' => 'Garage Door'

$auth = array(
      'auth'             =>  true,
      'host'             =>  '',
      'username'         =>  '',
      'password'         =>  'redacted'

$smtp = $mail->factory('smtp', $auth);
$smtp->send('', $headers, 'The garage door has been activated.');



$switch = exec('/usr/local/bin/gpio read 1');

if ($switch == "1"){
            echo "<img src='garage-door-open.jpeg' width='497px' height='448px'/>";
if ($switch == "0"){
            echo "<img src='garage-door-close.jpeg' width='497px' height='448px'/>";
