ID: 31529 User updated by: david at 21stcd dot com Reported By: david at 21stcd dot com Status: Bogus Bug Type: Scripting Engine problem Operating System: windows xp PHP Version: 4.3.8 New Comment: even so "\x".$hex will not work either. It was my understanding you could subsitiute vars into strings using the previous method I outline, where as the on I just outlined add the vars value onto the end of the string.
