我有以下代码：
foreach ($cardSuits as $cardSuit) {
$keyCardValues = array_keys($cardValues);
foreach ($keyCardValues as $cardValue) {
$deck[] = array( "cardValue" => $cardValue, "cardSuit" => $cardSuit);
shuffle($deck);
}
}
if ($deal == "Deal") {
shuffle($deck);
$cards1 = array_shift($deck);
$_SESSION['value'][] = $cards1;
我试过了：
echo "<br />" . $_SESSION['value']['cardValue'];
但这给了我一个未定义的索引错误。但是，如果我执行print_r，它就可以正常工作。我如何回显它，以便会话可以给我数组中的$ cardValue？
谢谢
编辑print_r：
Array ( [value] => Array ( [0] => Array ( [cardValue] => nine [cardSuit] => hearts ) ) [cards] => Array ( [0] => 9 [1] => 2 [2] => 10 [3] => 4 [4] => 3 [5] => 10 [6] => 5 [7] => 2 [8] => 10 [9] => 5 ) )
编辑回显print_r：
Array ( [value] => Array ( [0] => Array ( [cardValue] => nine [cardSuit] => diamonds ) ) [cards] => Array ( [0] => 9 [1] => 3 [2] => 7 [3] => 10 [4] => 9 [5] => 11 [6] => 7 [7] => 10 [8] => 10 [9] => 5 ) )
由于您$cards1是一个数组，并且您正在将该数组分配给$_SESSION['value'][]，因此您要cardValue使用以下内容进行访问：
echo "<br />" . $_SESSION['value'][0]['cardValue'];
