Why redirect not working? - php

Question

I am trying to log to data base all URL that user type.
After this if the path exists I want to redirect the user to path
Else I want to leave the user in the root directory.
The URL that I type http://www.mydomain.com/folder1/index.php
The output screen
folder1/index.php
Array ( [0] => folder1 [1] => index.php ) url = to folder 1
folder1/index.php
The root directory index.php
<?php
if ($_GET['url']!= "") {
// url not empty there is query string
$url = $_GET['url'];
$url = rtrim($url, '/');
echo ($url.'<br />');
$url = explode('/', $url);
$file = $url[0];
print_r($url);
}
else // url empty it is root directory
{echo ('<br /> url empty <br />');}
if ($url[0] == 'folder1'){
echo ('url = to folder 1<br />');
$path = $url[0].'/index.php';
//the path exists do redirect to folder1/index.php
echo $path ;
header( 'Location: http://www.mydomain.com/{$path}' ) ;
}
?>
The Htaccess
RewriteEngine on
Rewritecond %{HTTP_HOST} !^www\.mydomain\.com
RewriteRule (.*) //www.mydomain.com/$1 [R=301,L]
RewriteRule \.(sql)$ - [F]
RewriteRule \.(txt)$ - [F]
RewriteRule \.(zip)$ - [F]
RewriteRule \.(rar)$ - [F]
<IfModule mod_rewrite.c>
# For security reasons, Option followsymlinks cannot be overridden.
# Options +FollowSymLinks

Options -Indexes
RewriteEngine On
RewriteCond %{http_host} ^mydomain.com [NC]
RewriteRule ^(.*)$ http://www.mydomain.com/$1 [R=301,NC]
RewriteRule ^([^\.]+)$ index.php?url=$1 [QSA,L,NE]
</IfModule>
RewriteEngine On
RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^(.+)$ index.php?url=$1 [QSA,L,NE]
Many thanks

Answer 1

I think its the quote problem change with double quotes
header( "Location: http://www.mydomain.com/{$path}" ) ;

Answer 2

Remove the echo before this line and write exit(); after that
header( "Location: http://www.mydomain.com/{$path}" );
exit();

Answer 3

You cannot have any output before any header line, so you have to remove all echoes before the header location sentence:
<?php
if ($_GET['url']!= "") {
// url not empty there is query string
$url = $_GET['url'];
$url = rtrim($url, '/');
$url = explode('/', $url);
$file = $url[0];
}
else // url empty it is root directory
{}
if ($url[0] == 'folder1'){
$path = $url[0].'/index.php';
//the path exists do redirect to folder1/index.php
header( "Location: http://www.mydomain.com/$path" ) ;
}
And as you are using a variable inside the string, you shall use double quotes instead of single ones.

Answer 4

You should use like this, (i.e) php variable should come out of quotes and get concatenated,
header( "Location: http://www.mydomain.com/".$path) ;
Remove the echo before redirecting - MUST

Answer 5

Any html out put should not be there before the
header( 'Location: http://www.mydomain.com/{$path}' ) ;
Following 2 lines will be helped you to avoid htlm before the header statement.
Put ob_start(); in begin of your code.
Put ob_end_flush() end of your code.
Thanks.
