我们如何在 PHP 中迭代和访问关联的客队比分

我们如何从这个关联数组中访问客队的比分？ 下面是使用访问器在 PHP 中执行print_r时的关联数组的输出 $preGamesSorted[$e][away][score]，但没有任何显示。

(
[0] => Array
    (
        [state] => final
        [startTimeDisplay] => 12:00 PM ET
        [startTimeEpoch] => 1426262400
        [home] => Array
            (
                [rank] => 24
                [name] => Davidson
                [winner] => true
                [record] => 24-6
                [score] => 67
            )
        [away] => Array
            (
                [rank] => 0
                [name] => La Salle
                [winner] => false
                [record] => 17-16
                [score] => 66
            )
    )

这是 php 代码：

    <?php
 $url = file_get_contents("http://i.turner.ncaa.com/sites/default/files/external/test/scoreboard.json");
 $turnerNCAAJsonObject = json_decode($url,true);
 $liveGames = array();
 $finalGames = array();
 $preGames = array();
for ($n = 0; $n <= count($turnerNCAAJsonObject); $n++) {
    if(isset($turnerNCAAJsonObject[$n][state]) && $turnerNCAAJsonObject[$n][state] == 'final') {
        array_push($finalGames, $turnerNCAAJsonObject[$n]);
    }elseif (isset($turnerNCAAJsonObject[$n][state]) && $turnerNCAAJsonObject[$n][state] == 'pre') {
        array_push($preGames, $turnerNCAAJsonObject[$n]);
    }elseif ($turnerNCAAJsonObject[$n][state] == 'live') {
        array_push($liveGames, $turnerNCAAJsonObject[$n]);
    }
}
print_r($liveGames);
$finalGamesSorted = value_sort($finalGames, 'startTimeEpoch');
echo "<font color='"red'"><h3>Sorted Final Games</h3></font>";
//start of display for sorted final games
for ($e = 0; $e <= count($finalGamesSorted); $e++) {
    echo "<font color='"red'">";
    echo "Game Status: " . strtoupper($finalGamesSorted[$e][state]);
    echo "<br>";
    echo $preGamesSorted[$e][home][name] . " (" . $preGamesSorted[$e][home][rank] . ")" . " -VERSUS- " . $preGamesSorted[$e][away][name] . " (" . $preGamesSorted[$e][away][rank] . ")";
    echo "<br>";
    echo "Home Team's Record: " . $preGamesSorted[$e][home][record] . " -VERSUS- Away Team's Record: " . $preGamesSorted[$e][away][record];
    echo "<br>";
    //print_r($preGamesSorted[$e][startTimeEpoch]);
    echo "</font>";
    echo "<h3>" . $preGamesSorted[$e][home][score] . "-" . $preGamesSorted[$e][away][score] . "</h3>";
    //echo $preGamesSorted[$e][home][score];
    foreach ($finalGamesSorted[$e] as $title => $gameSpecifics) {
            foreach ($gameSpecifics as $stateKey => $stateValue){
                echo "<b><u>";
                print "$stateKey : $stateValue<br />";
                echo "</b></u>";
            }
                echo "<br>";
    }
    echo "<br>";
}
?>

数组输出是在变量$finalGamesSorted上执行print_r时显示的内容。 此外，函数value_sort，按数组的一个数字键对数组进行排序。
