Passing parameters from one PHP to WEB SITE

Question

I am setting a parameters in my PHP page and need to pass it to another WEB SITE, to execute operation on the WEB SITE (i don't need to get re result). I use header ("location : https://localhost/test=123") but its not executing it and display:

Warning: Cannot modify header information - headers already sent by (output started at /Applications/XAMPP/xamppfiles/htdocs/script1.php:33) in /Applications/XAMPP/xamppfiles/htdocs/script1.php on line 106

How can i simply just invoke it one time?

if there is solution from bash file,also can help...

The header function can only be used before ANY output is displayed on the screen.
For example:

 <?php
    echo( 'test' );
    header('location: www.google.com');
 ?>

Would fail with that error you reported.

thanks, i cancel all the `echo` and its worked! Can i do it without actually be redirected to that site? – Oleg Jun 07 '12 at 14:03
As stated in one of the answers below, file_get_contents() would send a request to the given URL, without redirecting you to the site. – Ben Poulson Jun 07 '12 at 15:04

You already output content to use header(). I would recommend:

$sRemotePage = file_get_contents('https://localhost/test=123');

You can use the HTTP meta element to set where the browser redirects the user. It needs to look like this:

<meta HTTP-EQUIV="Refresh" content="0; url=http://localhost/test=123">

Where 0 is the number of seconds the browser will wait before redirecting, and url is the redirected URL.

The other option would be using Output Buffering, but I am not entirely sure what you want to do and whether it can include ob_ or not.
