How can htmlspecialchars be utilized in PHP to handle special characters in code?

Special characters in user input can pose security risks, such as cross-site scripting attacks. Using the htmlspecialchars function in PHP helps to prevent these risks by converting special characters into their HTML entity equivalents. This ensures that the input is displayed as text on the webpage rather than being interpreted as HTML code. 

// Example of utilizing htmlspecialchars to handle special characters in PHP
$userInput = "<script>alert('Hello!');</script>";
$safeInput = htmlspecialchars($userInput, ENT_QUOTES);

echo $safeInput; // Output: <script>alert('Hello!');</script>
