What are some potential security risks of displaying PHP code in the browser?

Displaying PHP code in the browser can pose security risks as it can expose sensitive information such as database credentials, API keys, or other proprietary code. To prevent this, it's important to ensure that PHP code is not directly accessible by users in the browser. One way to achieve this is by configuring the server to parse PHP files before serving them to the client, ensuring that the PHP code is executed on the server-side and only the output is sent to the browser.

// Ensure that PHP files are parsed by the server before serving them
// Add this line to your .htaccess file
AddType application/x-httpd-php .php
