If you’d like to use unset
, the correct syntax would be unset($cards[1]); unset($cards[2]); unset($cards[3]); ...
and so on.
However, for your particular situation, I’ll recommend you to use array_slice
:
$cards = array(
"Messi", "Ronaldo", "Ibrahimovic", "Ribery", "Robben", "Neymar", "Rooney", "Casillas",
"Falcao", "Van Persie", "Hazard", "Iniesta", "Xavi", "Schweinsteiger", "Silva", "Fabregas",
"Lahm", "Aguero", "Cavani", "Vidic", "Ozil", "Mata", "Bale", "ThiagoSilva",
"Kompany", "Tevez", "Toure", "Ramos", "Suarez", "Pirlo", "DiMaria", "Neuer",
"Pique", "Buffon", "Lewandowski", "Gomez", "Chiellini", "Cole", "Pedro", "Busquets",
"Cech", "Muller", "Hummels", "Alonso", "Navas", "Modric", "Cazorla", "Gotze",
"Benzema", "Vidal", "Lavezzi"
);
shuffle($cards);
$cards = array_slice($cards, 0, 10);
For the horizontal display, you may simply omit the <br>
at the end of every iteration of your loop, but, depending on the resolution of the user’s browser, the images may occupy more than one line. For a strictly horizontal arrangement, use an HTML table with 10 columns:
print("<table><tr>");
foreach($cards as $card){
$img = "http://d2bm3ljpacyxu8.cloudfront.net/fit/105x97/http://clearpkz.webs.com/webstore/".$card.".png";
print("<td><img src=\"".$img."\"/></td>");
}
print("</tr></table>");
