redirect - PHP redirecting not showing content of the page redirected to

Page1.php code;

...
header('Location: editt.php?msg=landing&msisdn='.$msisdn);
...

page2.php code;

$msisdn = $_GET['msisdn'];
$msg = $_GET['msg'];
echo 'Page 2 Content '.$msisdn;

Answer

why not using header as container of your data :

header('msg: msgValue');
header('msisdn: msisdnValue');
header('Location: editt.php');

in edit.php

$headers = apache_request_headers();

foreach ($headers as $header => $value) {

    echo "$header: $value 
\n";
}
