Www to Non-Www Redirect with PHP

WWW to non-WWW Redirect with PHP

$pageURL = (@$_SERVER["HTTPS"] == "on") ? "https://" : "http://";
if ($_SERVER["SERVER_PORT"] != "80")
{
    $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} 
else 
{
    $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
header('Location: '. $pageURL);

Would redirect the user to the exact same page, www. intact.

So, to get rid of the www. , we just replace one line:

$pageURL = (@$_SERVER["HTTPS"] == "on") ? "https://" : "http://";
if ($_SERVER["SERVER_PORT"] != "80")
{
    $pageURL .= substr($_SERVER['SERVER_NAME'], 4).":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} 
else 
{
    $pageURL .= substr($_SERVER['SERVER_NAME'], 4).$_SERVER["REQUEST_URI"];
}
return $pageURL;

And that should work.

By the way, this is the method that is recommended by Google, as it keeps https:// intact, along with ports and such if you do use them.

As Gumbo pointed out, he uses $_SERVER['HTTP_HOST'] as it comes from the headers instead of the server, thus $_SERVER['SERVER_*'] is not as reliable. You could replace some$_SERVER['SERVER_NAME'] with $_SERVER['HTTP_HOST'], and it should work the same way.

Redirect non-www to www using php header() function

You can do it like:

if (strpos($_SERVER['HTTP_HOST'], 'www') === false) {
    $protocol = isset($_SERVER['HTTPS']) && filter_var($_SERVER['HTTPS'], FILTER_VALIDATE_BOOLEAN)
        ? 'https'
        : 'http';
    header(
        "Location: $protocol://www." . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'],
        true,
        301
    );
}

Redirect from www to non-www in php?

You could create a .htaccess file with the following content:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]

The answer in this question explains a solution using PHP instead.

Redirect http to https and www to non-www in .htaccess

Redirect to https and non-www

To instead redirect all requests to https and non-www, use the following code instead of the previous:

Canonical HTTPS/non-WWW

<IfModule mod_rewrite.c>
    RewriteCond %{HTTPS} off [OR]
    RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
    RewriteRule (.*) https://example.com/$1 [L,R=301]
</IfModule>

As before, place this code in the root .htaccess of your site. Here is what it's doing:

• Checks if mod_rewrite is available

• Checks if HTTPS is off, or if the request includes www

• If either condition matches, the request qualifies and is redirected
  to the https/non-www address

OR

RewriteEngine On
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [L,NE,R=301]

Redirect from www to non-www not working

You need to move this block before the other expressions:

<IfModule mod_rewrite.c>
    RewriteEngine On
#   RewriteCond %{HTTPS} !=on
    RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
    RewriteRule ^ %{ENV:PROTO}://%1%{REQUEST_URI} [R=301,L]
</IfModule>

Although you have the L tag in the previous one, so it should be the last rule applied, it doesn't work (probably because your activate the RewriteEngine again later so it resets the rules, but if the L flag was active in the first rule, it wouldn't apply the www one anyway).

The rule of thumb is: first do your cosmetic changes to the domain, then apply the functional rules.

You also don't need to open 2 IfModule conditions. Combine the 2 in one as this:

<IfModule mod_rewrite.c>

    # (1)
    RewriteEngine On

    # (2)
    Options +FollowSymlinks

    # (3)
    #Options +SymLinksIfOwnerMatch

    # (4)
    #RewriteBase /

    # (5)
    #RewriteOptions <options>

    # (6)
    RewriteCond %{HTTPS} =on
    RewriteRule ^ - [env=proto:https]
    RewriteCond %{HTTPS} !=on
    RewriteRule ^ - [env=proto:http]

#   RewriteCond %{HTTPS} !=on
    RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
    RewriteRule ^ %{ENV:PROTO}://%1%{REQUEST_URI} [R=301,L]

    # Send would-be 404 requests to Craft
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} !^/(favicon\.ico|apple-touch-icon.*\.png)$ [NC]
    RewriteRule (.+) index.php?p=$1 [QSA,L]

</IfModule>

How to redirect non-www to www in my domain

You can specify the domain you want to redirect:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^example\.com$
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

redirection issue in www to non www with ssl/https

Try this out:

To redirect www to non-www (while using SSL)

RewriteCond %{HTTP_HOST} ^www.your_domain.com$
RewriteCond %{SERVER_PORT} ^443
RewriteRule ^(.*)$ https://your_domain.com/$1 [R=301]

The last 2 are meant for online stores using SSL or to prevent any SSL errors while using SSL on some pages.

Update1:

RewriteEngine On

RewriteCond %{HTTPS} off
RewriteCond %{ENV:HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301,NE]

RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [L,R=301,NE]

Update 2

RewriteEngine On
Make all http use https:

RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://xxx.yyy/$1 [L,R=301]

Make only www https use the non-www https:

RewriteCond %{SERVER_PORT} 443
RewriteCond %{HTTP_HOST} ^www[.].+$
RewriteRule ^(.*)$ https://xxxx.yyy/$1 [L,R=301]

Update 3:
