What role does error handling play in PHP scripts when dealing with file operations like renaming or creating directories?

When dealing with file operations in PHP scripts, error handling is crucial to ensure that the operations are executed successfully and to handle any potential issues that may arise, such as file not found errors or permission denied errors. To handle errors when renaming or creating directories, you can use functions like `rename()` and `mkdir()` along with error handling techniques like try-catch blocks or checking the return values of these functions. 

// Example of error handling when renaming a file
$oldName = "old_file.txt";
$newName = "new_file.txt";

try {
    if (!rename($oldName, $newName)) {
        throw new Exception("Error renaming file.");
    }
    echo "File renamed successfully.";
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}

// Example of error handling when creating a directory
$directory = "new_directory";

try {
    if (!mkdir($directory)) {
        throw new Exception("Error creating directory.");
    }
    echo "Directory created successfully.";
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
