PHP: Hypertext Preprocessor (or simply PHP) is a server-side scripting language designed for web development but also used as a general-purpose programming language. It was originally created by Rasmus Lerdorf in 1994.

The PHP interpreter only executes PHP code within its delimiters. Anything outside its delimiters is not processed by PHP, although non-PHP text is still subject to control structures described in PHP code. stackofcodes.in

The most common delimiters are to close PHP sections. The shortened form <? also exists. This short delimiter makes script files less portable, since support for them can be disabled in the local PHP configuration and it is therefore discouraged.However, there is no recommendation against the use of the echo short tag <?=Prior to PHP 5.4.0, this short syntax for echo() only works with the short_open_tag configuration setting enabled, while for PHP 5.4.0 and later it is always available. The purpose of all these delimiters is to separate PHP code from non-PHP content, such as JavaScript code or HTML markup

Redirect a WordPress site from non-WWW to WWW

Redirect a WordPress site from non-WWW to WWW

The following tutorial will show you how to redirect your WordPress site’s domain from non-www to www or vice versa. Redirecting one to the other is useful for SEO.

If you go to https://www.wordpress.org, you’ll see the URL changes a bit once you click enter. It goes to the non-www version. In order words, it goes to https://wordpress.org. It’s a subtle change and it’s usually not noticed by users.

So why have they done this? It’s because, technically, the two are different domains but they have the same content. Without the redirect, they end up with duplicate content. With the redirect, they only have one site, so only one set of content.

With only one set of content, they guarantee they won’t be penalized by search engines or have their ranking split.

To move your site to non-www, find your .htaccess file using your host’s file manager or an FTP client.

Within it, look for the following code:

RewriteEngine On

If the code isn’t there, insert it at the top of your file.

Then, to redirect non-www to www, use the following code directly below RewriteEngine On:

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

For www to non-www, use:

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