What potential error handling improvements can be made in the PHP script provided?

The provided PHP script lacks proper error handling, which can lead to unexpected behavior or security vulnerabilities. To improve error handling, we can use try-catch blocks to catch exceptions and handle errors gracefully. Additionally, we can implement error reporting and logging mechanisms to track and troubleshoot issues more effectively. 

try {
    // Code that may throw exceptions or errors
    $file = 'example.txt';
    if (!file_exists($file)) {
        throw new Exception("File not found");
    }
    
    $content = file_get_contents($file);
    if ($content === false) {
        throw new Exception("Failed to read file");
    }
    
    // Process the file content
    echo $content;
} catch (Exception $e) {
    // Handle exceptions
    echo "An error occurred: " . $e->getMessage();
    // Log the error
    error_log("Error: " . $e->getMessage());
}
