To automatically escape incoming data in PHP, you can use functions like htmlspecialchars() or htmlentities(). These functions convert special characters to their corresponding HTML entities, preventing them from being interpreted as HTML or potentially causing cross-site scripting (XSS) attacks. By applying these functions to user input or any data that will be displayed on a webpage, you can ensure that the data is properly escaped and does not pose a security risk. For example, you can use htmlspecialchars($input) to automatically escape the $input variable. It's important to note that the specific function to use depends on the context in which the data will be used (e.g., displaying data in HTML, within an attribute value, etc.). Always consider the specific security requirements of your application and consult the PHP documentation for more details on proper data escaping techniques.
