Hi, I'm new to PHP. I installed XAMPP and have Apache running. I created helloworld.php in XAMPP's htdocs and got PHP to display in my browser. My question is, why does my PHP script in my HTML file not display in my browser? Ive never installed PHP on its own. Should I also install it? Would it conflict with XAMPP. My code is below. Any assistance will be appreciated. Thanks in advance:
<html>
<body>
<?php
echo "Hello PHP World";
?>
</body>
</html>
XAMPP already includes PHP, but unless you end the script name with .php it is unlikely to be processed by the PHP engine.
The php module for apache registers itself as handler for the mime type application/x-httpd-php. And the configuration file apache\conf\extra\httpd-xampp.conf contains the lines
<FilesMatch "\.php$">
SetHandler application/x-httpd-php
</FilesMatch>
which tells the apache that all files having .php as name extension are to be processes by the handler for application/x-httpd-php.
If you (really) want to have your .html files handled by the php module as well you have to add something similar for .html extensions. (there are other methods to tell the apache which extension maps to which mime type/handler. But FilesMatch/SetHandler is fine.)
If you want to enable this "feature" for only one directory you can use an .htaccess file to change the configuration for that directory (and its subdirectories).
I assume you are trying to use php inside .html file? Try adding .htaccess file or changing apache config with the following line:
AddHandler application/x-httpd-php .html
