What potential issues might arise from directly accessing POST variables within a class in PHP, and what are some alternative approaches to handle this data securely?

Directly accessing POST variables within a class in PHP can lead to security vulnerabilities such as injection attacks or data manipulation. To handle POST data securely within a class, it is recommended to pass the data as parameters to class methods instead of directly accessing them. 

// Incorrect way of accessing POST variables within a class
class MyClass {
    public function processData() {
        $data = $_POST['data'];
        // Process the data
    }
}

// Correct way of handling POST data securely within a class
class MyClass {
    public function processData($data) {
        // Process the data
    }
}

// Usage
$myClass = new MyClass();
$data = $_POST['data'];
$myClass->processData($data);
