How can escaping characters be effectively utilized in PHP to maintain code integrity?

Escaping characters in PHP is essential to maintain code integrity by preventing code injection attacks and ensuring that user input is properly handled. This can be done using functions like `htmlspecialchars()` or `mysqli_real_escape_string()` to escape special characters before storing or displaying user input. 

// Example of using htmlspecialchars() to escape characters in PHP
$user_input = "<script>alert('Hello, world!');</script>";
$escaped_input = htmlspecialchars($user_input);
echo $escaped_input;
