How can PHP code be securely executed on a server without compromising the integrity of the application?

To securely execute PHP code on a server without compromising the integrity of the application, it is important to properly sanitize user input, validate input data, and avoid using deprecated or vulnerable functions. Additionally, implementing security measures such as input validation, output encoding, and using prepared statements for database queries can help prevent SQL injection attacks. 

<?php
// Sanitize user input
$input = filter_var($_POST['input'], FILTER_SANITIZE_STRING);

// Validate input data
if (strlen($input) > 0) {
    // Execute secure PHP code
    // Your secure PHP code here
} else {
    // Handle error or display message
}
?>
