What are the potential pitfalls of using text file databases in PHP, and how can they be mitigated?

One potential pitfall of using text file databases in PHP is the lack of efficiency and scalability compared to traditional databases. This can lead to slower performance and difficulty managing large amounts of data. To mitigate this, consider implementing caching mechanisms to reduce the number of file reads and writes, as well as optimizing the file structure for faster access. 

// Example of implementing caching mechanism to improve performance
function get_data_from_text_file($file_path) {
    $cache_file = 'cache.txt';
    
    if (file_exists($cache_file) && filemtime($cache_file) > filemtime($file_path)) {
        return file_get_contents($cache_file);
    } else {
        $data = file_get_contents($file_path);
        file_put_contents($cache_file, $data);
        return $data;
    }
}

// Usage
$data = get_data_from_text_file('data.txt');
