PHP on EC2 is just printing out my PHP file and not executing

Question

I have this as my index.php on a basic EC2 instance.

<?php
$conn =  new mysqli('localhost', 'testdb_user', 'testpass', 'testdb', '');
$result = $conn->query("SELECT message FROM test");
$row = $result->fetch_assoc();
echo $row['message'];
?>

When I visit my public DNS I get this:

query("SELECT message FROM test"); $row = $result->fetch_assoc(); echo $row['message']; ?> 

printed to the browser.

I've installed php and the table in mysql is fine (i have repleaced db name etc with my actual credentials.

Answer 1

You have either installed PHP incorrectly or failed to restart your web server after installing it. If it's apache, try this:

/etc/init.d/httpd restart

It doesn't have anything to do with your mysql config - php is not trying to execute the script at all.

Answer 2

In my case PHP cli was working on ec2 ubuntu instance and as you said browser just prints source code instead of executing it

sudo apt-get update
sudo apt-get install apache2
sudo apt-get install libapache2-mod-php php
sudo apt-get install mysql-server php-mysql
sudo service apache2 restart

I have run from 3rd line (install php) and that fixed my issue
