How can PHP be used to handle errors that may arise during file manipulation operations?

When handling errors during file manipulation operations in PHP, it is important to use error handling techniques such as try-catch blocks to catch and handle any exceptions that may occur. This allows for graceful error handling and prevents the script from crashing when errors are encountered. 

try {
    // Attempt to open a file for reading
    $file = fopen("example.txt", "r");
    
    // Check if the file was successfully opened
    if (!$file) {
        throw new Exception("Error opening file");
    }
    
    // Perform file manipulation operations here
    
    // Close the file
    fclose($file);
} catch (Exception $e) {
    // Handle the error
    echo "An error occurred: " . $e->getMessage();
}
