How can one troubleshoot the error message "the page cannot be found" when working with PHP applications?

The error message "the page cannot be found" typically indicates an issue with the URL or the file path in the PHP application. To troubleshoot this error, check that the URL is correct and that the file path in the PHP code matches the actual file location on the server. Additionally, ensure that the file has the correct permissions set to be accessed by the server. 

<?php

// Ensure the file path is correct
include 'path/to/file.php';

// Check the URL for any typos
if($_SERVER['REQUEST_URI'] == '/path/to/page'){
    // Code to display the page content
} else {
    // Redirect to an error page
    header("Location: /error-page.php");
    exit();
}

?>
