Re: Re: strange stripos behavior

For another guru, I have a question. I just checked the returns of this func on php.net to check myself and I see: This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE, such as 0 or "". When would stripos() return "" ? Thanks! -Shawn Bruce Cowin wrote: > Thanks for the suggestion.
