I try to run a PHP script from command line to check if a specific webserver is running, but it doesn't work.

This one works:

$to = 'mail@address.com';
$subject = 'LSWS Check';
$message = 'Apache is Running';
$headers = 'From: root' . "\r\n" . 'Reply-To: mail@address.com' . "\r\n" . 'X-Mailer: PHP/' . phpversion();

$serverSoftware = $_SERVER['SERVER_SOFTWARE'];
$isWebserver = 'Apache';

mail($to, $subject, $message, $headers);

This one doesn't work:

$to = 'mail@address.com';
$subject = 'LSWS Check';
$message = 'Apache is Running';
$headers = 'From: root' . "\r\n" . 'Reply-To: mail@address.com' . "\r\n" . 'X-Mailer: PHP/' . phpversion();

$serverSoftware = $_SERVER['SERVER_SOFTWARE'];
$isWebserver = 'Apache';

if (strpos($_SERVER[$serverSoftware], $isWebserver) !== false) {
  mail($to, $subject, $message, $headers);
}

strpos($_SERVER[$serverSoftware] doesn't work, but why?

    Not all $_SERVER variables are accessible from command line, do a var_dump($_SERVER); just to be sure. Also your `strpos($_SERVER[$serverSoftware], $isWebserver)` should be `strpos($serverSoftware, $isWebserver)` – Bert Maurau Apr 02 '20 at 08:14
  • how do you run the script from command line? – Gihan Apr 02 '20 at 08:19

  • I checked variables with var_dump($_SERVER) and $_SERVER['SERVER_SOFTWARE'] isn't available. Is there any workaround? – Serpentdriver Apr 02 '20 at 08:25
