Which one is a more reliable matching scheme, EREGI or STRIPOS?

Question

Which scheme according to you is a better one in case of matching?

Is it eregi or stripos or any other method?

Answer 1

That depends if you want to do exact match or regexp match.

• stripos is for case insensitive matching of string in another string
• eregi is case insensitive regexp matching in a string
• fnmatch is the third alternative. It's simple wildcard matching as in globbing.

Moreover, eregi is deprecated, is not binary safe and does not work well with UTF-8. For regexp matching you should use preg_match with i flag instead.
