What are the potential reasons for a PHP script not outputting any content, even when there are no visible script errors?

The potential reasons for a PHP script not outputting any content, even when there are no visible script errors, could be due to a missing `echo` or `print` statement in the script, an issue with the server configuration, or an error in the logic of the script that prevents it from generating output. To solve this issue, you should check the script for any missing output statements, ensure that the server is properly configured to execute PHP scripts, and debug the script to identify any logic errors that may be causing the lack of output.

<?php
// Example PHP script that may not output any content
// Check for missing output statement
echo "Hello, World!";
?>
