    the header() function needs to be the first header set... Sooooo try and get it as high in your code as possible. I'll include in the – Shan Robertson Sep 06 '13 at 23:41
  • When all else fails you may consider `ob_start();` and `ob_end_flush();`. – StackSlave Sep 06 '13 at 23:44
  • `header('Location: http://www.yoursite.com/new_page.html');` this line is causing the error. Please check @relentless's link to be informed. – samayo Sep 07 '13 at 00:01
  • Any output, echo, var_dump, whitespace, anything before header will cause this. – Phix Sep 07 '13 at 00:13

You're trying to print output with your var_dump($response); statement before using header(). Move your header() function before any output, or wrap your code in the output buffer using ob_start() and ob_end_flush()

  • ` sendSMS($username, $password, $numbers, $message, $senderName); header('Location: http://www.yoursite.com/new_page.html'); var_dump($response); } catch(SoapFault $exception ) { echo $exception->faultcode . ' : ' .$exception->faultstring . PHP_EOL; } ?> ` – hossam365 Sep 07 '13 at 03:24
  • Mate your code is not intelligible in this way. If u got the suggestions we gave, you should be able now to refactor your code so that every output statement (var_dump, print_r, print, echo, etc.) comes after any header() call – brazorf Sep 09 '13 at 17:19
