What are the best practices for handling dynamically generated files in PHP, specifically when using the file_put_contents and file_get_contents functions?

When handling dynamically generated files in PHP using functions like file_put_contents and file_get_contents, it's important to ensure proper error handling and security measures. Always check if the file operations were successful and handle any potential errors. Additionally, sanitize user input to prevent vulnerabilities like directory traversal attacks. 

// Example of handling dynamically generated files with error handling and sanitization

// File path
$file_path = 'path/to/dynamic_file.txt';

// Data to write to file
$data = 'This is dynamically generated content.';

// Write data to file with error handling
if(file_put_contents($file_path, $data) !== false) {
    echo 'File created successfully.';
} else {
    echo 'Error creating file.';
}

// Read data from file with error handling
$file_contents = file_get_contents($file_path);
if($file_contents !== false) {
    echo 'File contents: ' . $file_contents;
} else {
    echo 'Error reading file.';
}
