[PHP]<?php
header("location:Redirecting.php");
exit;
?>

[/PHP]

It give me an error

[HTML]Warning: Cannot modify header information - headers already sent by (output started at C:\wamp\www\example\Signup.php:1) in C:\wamp\www\example\Signup.php on line 2[/HTML]

Hi.

The header() function MUST be called before you send anything to the browser... Even a white-space before the <?php tag will cause the error you are getting.

For example:

<?php
# This will not work, giving you the error you described.
echo "You will be redirected in 3 seconds...";
header("Refresh: 3; url=http://www.google.com");
?>
 

<?php
# This, however, will work.
header("Refresh: 3; url=http://www.google.com");
echo "You will be redirected in 3 seconds...";
?>
