string checking acting up

liam_d · 03-08-2008, 06:01 AM

Hi all basically i am trying to check if a string starts with "<embed" or "<object" and if it doesn't then give an error, i have found out if i do this then it never works:

PHP Code:

  if(substr($_POST['code'], 0, 6) != "<embed" || substr($_POST['code'], 0, 7) != "<object")

but if i do just one so if you remove the or bit for "<object" it works, but it won't let me do both together, any ideas?!

Perhaps if would be good to use strtolower or strtoupper to perform a case-insensitive comparison. A regular expression could be used too.
