How can sending scripts via instant messaging applications affect PHP code execution?

Sending scripts via instant messaging applications can potentially expose PHP code to security risks if the script is executed without proper validation. To mitigate this risk, it is crucial to sanitize and validate any input received from instant messaging applications before executing it as PHP code. This can be done by using functions like htmlspecialchars() to prevent XSS attacks and eval() to execute the code securely. 

// Sanitize and validate input received from instant messaging applications
$input = $_POST['message']; // Assuming the input is received via POST method

// Sanitize the input
$sanitized_input = htmlspecialchars($input);

// Validate and execute the sanitized input as PHP code
eval($sanitized_input);
