halben Posted September 17, 2013 Share Posted September 17, 2013 Hello Guys/Gals, Can someone please tell me how safe this sanitation is? $username = filter_var($_POST['user_name'], FILTER_SANITIZE_STRING); Thanks, Halben Quote Link to comment Share on other sites More sharing options...
AbraCadaver Posted September 17, 2013 Share Posted September 17, 2013 Depends upon what you need. What are you hoping that will do? Make it safe for what? Quote Link to comment Share on other sites More sharing options...
halben Posted September 17, 2013 Author Share Posted September 17, 2013 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? Quote Link to comment Share on other sites More sharing options...
AbraCadaver Posted September 17, 2013 Share Posted September 17, 2013 (edited) 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.
