Using ereg is a security hole

Hi!

Interesting slide, but in this I disagree with you:
"Perl regular expressions (pcre) not UTF-8 safe.
If you are processing user input, must use ereg regular expressions"

1. What is the problem with the /u modifier at PCRE?
2. Using ereg for input validating is not a good idea while it is not binary safe. You can test it with inserting a \0 character into a request variable: ereg will think that this is the end of the string (this is caused by the internal representation of strings in PHP), and doesn't validate the rest of it.

Best Regards,
Felhő

thanks
