These two lines in your code not make sense:
Code: [Select]
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.flowersmanama.com");
First, you're outputting part of HTML page, and then suddenly making redirect.
If you want to redirect to another page, these two lines must be above any HTML code in your php script, like this:
PHP Code: [Select]
<?
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.flowersmanama.com");
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

When i put the code at the top of the file, the way you told me, the website is not opening:

The page isn't redirecting properly
     
     
     
     
     
       
       
          Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
       

       
       

  This problem can sometimes be caused by disabling or refusing to accept
    cookies.

any other suggestions?

i am trying to add the following code:

PHP Code: [Select]

<?php
    function currentPageURL() {
    $curpageURL = 'http';
    if ($_SERVER["HTTPS"] == "on") {$curpageURL.= "s";}
    $curpageURL.= "://";
    if ($_SERVER["SERVER_PORT"] != "80") {
    $curpageURL.= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
    } else {
    $curpageURL.= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
    }
    return $curpageURL;
    }

    $FullUrl = currentPageURL();
    if ($FullUrl = "http://flowersmanama.com/")
        {

IT IS WOKING NOW With the following code:

Code: [Select]

<?
session_start();
function currentPageURL() {
    $curpageURL = 'http';
    if ($_SERVER["HTTPS"] == "on") {$curpageURL.= "s";}
    $curpageURL.= "://";
    if ($_SERVER["SERVER_PORT"] != "80") {
    $curpageURL.= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
    } else {
    $curpageURL.= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
    }
    return $curpageURL;
    }

    $FullUrl = currentPageURL();
    $url ="http://flowersmanama.com/";
    if ($FullUrl == $url)
        {
                Header( "HTTP/1.1 301 Moved Permanently" );
                Header( "Location: http://www.flowersmanama.com/" ); 
                               
        }

I am confused what is the Old url/page and what is the new URL.

If I am reading this correctly your issuing a 301 error for that page then forwarding right back to that page. It cannot be Permanently moved and at the same url.

That's what i'm reading as well. If you're just adding the www part, you can do that with .htaccess rather than a whole script
