Are there any specific guidelines or recommendations for handling file inclusions in PHP scripts?

When including files in PHP scripts, it is important to ensure that the included files are secure and do not pose any security risks such as directory traversal attacks. To mitigate this risk, it is recommended to use absolute file paths or sanitize user input before including files. 

// Example of including a file with sanitized user input
$included_file = 'path/to/secure/file.php';
if (file_exists($included_file)) {
    include $included_file;
} else {
    echo 'File not found.';
}
