Are there any security considerations to keep in mind when using PHP functions to extract content from HTML tags to prevent vulnerabilities like cross-site scripting (XSS)?
When extracting content from HTML tags using PHP functions, it's important to sanitize the input to prevent vulnerabilities like cross-site scripting (XSS). One way to do this is by using the `strip_tags()` function to remove any HTML tags from the input before processing it further.
$input = "<script>alert('XSS attack!');</script>";
$clean_input = strip_tags($input);
echo $clean_input;
