It has been common usage to utilise the isset() function to determine if a variable in PHP has a value. This is as opposed to checking the contents are not NULL or the empty string: "". I had utilised this facility thoroughly in the CRIMP code-base (available on source-forge under the same name), and was wondering why a certain scenario wasn’t being handled as I expected. Now, I knew I could work around the issue, but I felt I needed to find out what the actual cause was.
NOTE: this is a repost, the original post has disappeared. As Bender the robot from Futurama would say: OH.. YOUR.. GOD!! I found links to MP3s of popcorn!! For those of you that have never heard of popcorn, listen up.. Originally composed by one Gershon Kingsley, popcorn is one of the all-time greats. This track is instantly recognisable, and has been covered umpteen times. I found a site with 79 different cover versions of this Popcorn music track.
