How can PHP beginners effectively troubleshoot include-related issues?

When troubleshooting include-related issues in PHP, beginners should first ensure that the file path specified in the include statement is correct. They can use absolute paths or relative paths based on the current file location. Additionally, checking for any typos or syntax errors in the file names or paths is crucial. Lastly, beginners can use functions like file_exists() to verify if the included file exists before including it.

<?php
// Example of troubleshooting include-related issues
$included_file = 'path/to/included_file.php';

if (file_exists($included_file)) {
    include $included_file;
} else {
    echo 'Included file does not exist.';
}
?>
