Are there any best practices or recommended approaches for handling and processing data from system-generated files in PHP?

When handling and processing data from system-generated files in PHP, it is important to ensure proper error handling, data validation, and security measures are in place. One recommended approach is to use PHP's built-in functions like `file_get_contents()` or `fopen()` to read the file, validate the data using functions like `filter_var()` or regular expressions, and sanitize input using `htmlspecialchars()` or `mysqli_real_escape_string()` to prevent SQL injection attacks. 

// Example code snippet for handling and processing data from a system-generated file in PHP

// Read the contents of the file
$file_contents = file_get_contents('system_generated_file.txt');

// Validate the data - example validation using regular expression
if (preg_match('/^[0-9]{3}-[0-9]{2}-[0-9]{4}$/', $file_contents)) {
    // Data is valid, process further
    $sanitized_data = htmlspecialchars($file_contents);

    // Example of processing the data further
    echo "Processed data: " . $sanitized_data;
} else {
    // Data is not valid, handle error
    echo "Error: Invalid data format";
}
