What are some best practices for error handling in PHP, especially when dealing with file operations?

When dealing with file operations in PHP, it is crucial to implement proper error handling to gracefully handle any issues that may arise, such as file not found or permission errors. One best practice is to use try-catch blocks to catch exceptions and handle them accordingly, providing informative error messages to the user or logging the errors for debugging purposes. 

try {
    $file = fopen("example.txt", "r");
    if (!$file) {
        throw new Exception("Unable to open file.");
    }
    
    // File operations here
    
    fclose($file);
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}
