How can PHP developers ensure that their scripts comply with security guidelines set by hosting providers to avoid IP address blocking?

PHP developers can ensure that their scripts comply with security guidelines set by hosting providers by implementing proper input validation, sanitization of user inputs, and using secure coding practices. Additionally, developers should regularly update their PHP version and libraries to patch any security vulnerabilities. By following these guidelines, developers can reduce the risk of their scripts triggering IP address blocking by hosting providers. 

// Example of input validation and sanitization in PHP
$userInput = $_POST['user_input'];

// Validate user input
if (filter_var($userInput, FILTER_VALIDATE_EMAIL)) {
    // Sanitize user input before using it in the script
    $sanitizedInput = filter_var($userInput, FILTER_SANITIZE_STRING);
    
    // Use the sanitized input in the script
    echo "Sanitized input: " . $sanitizedInput;
} else {
    echo "Invalid email address";
}
