I installed apache2, php5 and the php5 apache module on Ubuntu 13.04.
Php is working on .php files but lines of php code inside html files do not execute.
Googling I found that must add AddHandler...
and AddType...
lines to httpd.conf but the version installed doesn't have this file or at least can't find it in /etc/apache2/
code example:
<html>
<head></head>
<body>
<?php
phpinfo();
?>
</body>
</html>
