Re: Looking for caveats to the following code

My initial thought is that it is safe since I'm simply checking for true/false-ness. I either check for '!== false' explicitly or (in the case of the latter example) check that something other than 'false' is returned. It's slightly less readable but it seems more efficient (if nothing more than to save on the number of lines typed). Thoughts?

Chris: You can shorten it even further by: if(do_something('hello')) { // do something with $result } else { // do some other stuff } I don't think it's any different than calling any other function that returns <whatever> or false. I tried it out at -- http://xn--ovg.com/a14.php -- with both pass and fail. All worked the same in all three ways. hth's tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com
