In honor of our recent Super Bowl, here is a slow-motion instant replay:
Bob: "Well, it's a great day so far for PHP today, isn't it Jim?"
Jim: "You've got that right, Bob! Now let's check out this play."
Bob: "Watch as the user surfs right to that web page!"
Jim: "Yeah, smooth!"
Bob: "Then, Apache detects the .php in the URL and hands off the action to
PHP!"
Jim: "PHP has been really strong today, hasn't it?"
Bob: "Sure has, Jim!"
Jim: "Then, PHP builds up some HTML and JavaScript and sends it out!"
Bob: "Yeah, and then PHP says 'Job Done.'"
Jim: "You've got that right, Bob! PHP is outta the game for now, resting."
Bob: "Now watch carefully as the user interacts with the browser."
Jim: "Pay particular attention as they change items in the filelist box."
Bob: "Oooooh! What a fumble!!!"
Jim: "Yeah, it's definitely much too late to be handing off to PHP!"
Bob: "Sure is, Jim. PHP has been out of the game now for awhile!"
