What is the EVA principle in PHP and how does it relate to data processing?

The EVA principle in PHP stands for Escape, Validate, and Aggregate. This principle is used in data processing to ensure that input data is properly sanitized, validated for correctness, and aggregated for further processing. By following the EVA principle, developers can prevent security vulnerabilities and ensure data integrity. 

// Example of implementing the EVA principle in PHP data processing

// Escape input data to prevent XSS attacks
$input_data = htmlspecialchars($_POST['input_data']);

// Validate input data to ensure correctness
if (filter_var($input_data, FILTER_VALIDATE_EMAIL)) {
    // Input data is a valid email address
} else {
    // Input data is not a valid email address
}

// Aggregate input data for further processing
$aggregated_data = $input_data . " additional information";
