There are times wherein you are required to parse HTML web pages as PHP. Suppose, you have older HTML web pages and you are required to add some additional functionality that can only be achieved by programming language like PHP. Will you modify each web page manually and add PHP code? This sound little impractical and monotonous task. To get rid of this exercise, you can parse HTML web pages as PHP using .htacccess file. All you need to do is, locate .htaccess file, add one of the following line according to your setup and save the file.

If your web server is using suPHP add following line in .httaccess.

AddHandler x-httpd-php .html .htm

OR

AddType application/x-httpd-php .html .htm

AddHandler application/x-httpd-php5 .html .htm

AddType application/x-httpd-php5 .html .htm
