PHP error: Cannot modify header information without any html/cookie/space

Question

I have a strange bug with my script, i just want redirect user if the URL finish by '/' to the same URL without any '/' at the end.

i get this error:

Warning: Cannot modify header information - headers already sent by (output started at /home/httpd/vhosts/xxx/httpdocs/series.php:1) in /home/httpd/vhosts/xxx/httpdocs/series.php on line 7

Warning: Cannot modify header information - headers already sent by (output started at /home/httpd/vhosts/mxxx/httpdocs/series.php:1) in /home/httpd/vhosts/xxx/httpdocs/series.php on line 8

Code:

<?php
$urlLast = $_SERVER['REQUEST_URI'];
$urlLast = substr($urlLast, -1);
if (($urlLast == '/') && (!strstr($_SERVER['REQUEST_URI'], 'en-streaming')))
{
    $newURL = substr($_SERVER['REQUEST_URI'],0,-1).'-en-streaming';
    header("Status: 301 Moved Permanently", false, 301);
    header("Location: ".$newURL."");
}

I would prefer a .htaccess but is there any error? And also check for the file encoding. If you have UTF8 _with_ BOM it may also fail (as with a space). — tea2code, Sep 04 '13 at 09:12
can i check if the url contain "en-streaming" and have a final / with a .htaccess file? I don'nt have any whitespace :/ — Bastien Bast Weber, Sep 04 '13 at 09:13
@BastienBastWeber Are you sure that there is no white space at all before line 7/8 — Daryl Gill, Sep 04 '13 at 09:15
Yes... I try to put a simple header("Location: test.php"); at the seconde line and i have the same error Warning: Cannot modify header information - headers already sent by (output started at /home/httpd/vhosts/xxx/httpdocs/series.php:1) in /home/httpd/vhosts/xxx/httpdocs/series.php on line — Bastien Bast Weber, Sep 04 '13 at 09:21

You can fix it by using

ob_start(); on the top of your script.

Is there Unicode BOM before <?php?

When you saved your file with encoding "UTF-8 with BOM(Byte Order Mark)", special character sequence(0xEF 0xBB 0xBF) would be automatically inserted in beginning of file.

Just try saving file with "UTF-8 WITHOUT BOM" (if exists) or try another editor.

AFAIK UTF-8 in notepad.exe is "WITH BOM".

Remove trailing spaces before <?php

Also, remove spaces after ?> (if any)

Also, add ob_start() at the beginning of the file.

This saves the output in buffer cache instead of printing on the browser.
