sanitizing strings question


Recommended Posts


I'm doing something like this:


$user_email_data = trim(strip_tags(stripslashes($_POST['user_email'])));
// Now use PHP to check for validation
if (filter_var($user_email_data, FILTER_VALIDATE_EMAIL)) { .....
How safe is that?



Validate and sanitize filters are different.  Sanitize will change it to make it "safe" and validate tells you whether it is valid or not.
