What best practices should be followed when including external PHP files within a script to avoid errors like the one mentioned in the forum thread?

The issue mentioned in the forum thread is likely related to including external PHP files without proper error handling. To avoid errors, it's essential to check if the file exists before including it and to use absolute paths instead of relative paths. 

// Check if the file exists before including it
$file = 'path/to/external/file.php';
if (file_exists($file)) {
    include $file;
} else {
    echo 'Error: File not found';
}
