So this is my 2nd PHP class ever. And this right here is part of my final.
I'm sure you all know what the "shuffle" function does. What I thought I could make it do was randomize a bunch of echoes I have. Is that possible? Any help would be greatly appreciated. KCCO! Here's the code I need tweaked: <html> <head> <title>Characters</title> <link rel="stylesheet" href="assets/css/bootstrap.css" media="screen"> <link rel="stylesheet" href="assets/css/bootstrap-responsive.css" media="screen"> <link rel="stylesheet" href="assets/css/normalize.css" type="text/css" media="screen"> <link rel="stylesheet" href="assets/css/style.css" media="screen"> </head> <body> <div class="navbar"> <div class="navbar-inner"> <a class="brand" href="#"></a> <ul class="nav"> <li class="active"><a href="Characters.php">Previous Clients</a></li> <li><a href="workForSupers.php">Work for Supers</a></li> </ul> </div> </div><!-- END of navbar--> <div align="center"> <h1>Supers we've helped locate</h1> <? date_default_timezone_set("America/Los_Angeles"); # set default timezone $imageDir = "images/"; # Comics is a PARENT class - Emily, Jenny, and so forth all are CHILDREN of Comics, meaning: They inherit the properties and methods included inside Comics. # For example: echo $joker->comiccharacters; will print out the $comiccharacters stored in Comics class Comics { const IMAGEDIR = "images/"; public $comiccharacters = "Comics"; } class Spiderman extends Comics { public $name = "Spiderman"; public $location = "New York City"; public $superpower = "his spider-sense, augmented speed and strength and his web shooters."; public $sex = "male"; public $published = "1963-03-01."; public $hero = true; public $asseskicked = 37; public $personscaught = [12,16,19,29,51]; public $powerlevel= '++++++'; public $email = "
