What steps can be taken to troubleshoot and resolve PHP display issues on localhost or 127.0.0.1?

Issue: If PHP files are not displaying correctly on localhost or 127.0.0.1, it may be due to incorrect configuration settings or errors in the PHP code. To troubleshoot and resolve this issue, check the PHP error logs for any error messages, ensure that the PHP module is enabled in your web server configuration, and validate the PHP syntax for any errors.

<?php
// Check PHP error logs for any error messages
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Ensure PHP module is enabled in web server configuration

// Validate PHP syntax for any errors
// Example syntax error: missing semicolon
echo "Hello, World"
?>
