sudo apt-get install apache2
sudo apt-get install php5
sudo apt-get install libapache2-mod-php5
sudo /etc/init.d/apache2 restart
I have done and created a test page test.php but the browser doesn't show any information
test.php content
<!--?php
phpinfo();
?-->
But the apache alone works (the browser loads the http://localhost/ just fine)
It should be:
<?php
phpinfo();
?>
Your current code seems like a malformed HTML comment.
