need to trim the string

[piyush23424]

Hello

i need a function that checks the  url like www.sitename.com or sitename.com

if it contains the "www." in the url then it should cut the "www." part from the url.

 

Thanks

$domain = $_SERVER['HTTP_HOST'];
$path = $_SERVER['REQUEST_URI'];
if($domain != 'site.com') { header("Location: http://site.com".$path.""); }

Just create an .htaccess file in the web root.

 

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

$domain = $_SERVER['HTTP_HOST'];
$path = $_SERVER['REQUEST_URI'];
if($domain != 'site.com') { header("Location: http://site.com".$path.""); }

 

I am not using this to redirect but there is a functionality in my site when i put www with domain name then it works and it doesn't work when i put the url like http://sitename.com

If you are wanting to modify a URL that is not related to the URL the user is currently viewing (i.e. user entered value), then this will work:

 

preg_replace("/www\./", '', $url);

 

It has one flaw. If the url contains 'www.' anywhere in the url it will be removed. Ex: "subdomainwww.domain.com" would become "subdomaindomain.com". I did that so it would work for values such as "http://www.domain.com". But, I think the likelyhood of such an occurance would be very remote.

 

However, if the values will always start from the subdomain (i.e. not 'http://') then this would be better:

preg_replace("/^www\./", '', $url);

Ok if you need the www. for the site to work then your apache rewrite rule would be this.

 

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