What are some alternatives to using the include function in PHP to insert text files?

Using the include function in PHP to insert text files can pose security risks if the file being included is user-controlled. To avoid this, you can use file_get_contents to read the file contents and then echo or print the contents directly in your PHP script.

$file_contents = file_get_contents('path/to/your/file.txt');
echo $file_contents;
