Question

我目前正在尝试PHP中的数组，并且我创建了一个假的环境，其中将显示团队的信息。

    $t1 = array (
            "basicInfo" => array (
                "The Sineps",
                "December 25, 2010",
                "lemonpole"
            ),
            "overallRecord" => array (0, 0, 0, 0),
            "overallSeasons" => array (
                1 => array (14, 0, 0),
                2 => array (9, 5, 2),
                3 => array (12, 4, 0),
                4 => array (3, 11, 2)
            ),
            "games" => array (
                "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />",
                "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />",
                "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />",
                "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />"
            ),
            "seasonHistory" => array (
                "Season I",
                "Season II",
                "Season III",
                "Season IV"
            ),
            "divisions" => array (
                "Open",
                "Main",
                "Main",
                "Invite"
            )
        );
// Displays the seasons the team has been in along
    // with the record of each season.
    function seasonHistory() {
        // Make array variable local-scope.
        global $t1;

        // Count the number of seasons.
        $numrows = count($t1["seasonHistory"]);

        // Loop through all the variables until
        // it reaches the last entry made and display
        // each item seperately.
        for($v = 0; $v <= $numrows; $v++) {
            // Echo each season.
            echo "<tr><td>{$t1["games"][$v]}</td>";
            echo "<td>{$t1["seasonHistory"][$v]}</td>";
            echo "<td>{$t1["divisions"][$v]}</td></tr>";
        }
    }

我已经测试了几个可能出现的问题，在缩小它们之后我得出了一个结论，那就是我的函数由于某种原因没有连接到数组。我不知道还能做什么，因为我认为使数组全局可以解决这个问题。

什么有效：

我可以在我需要显示的页面上回显 $ t1 [“games”] [0] ，它会给我内容。
我尝试回显 $ t1 [“games”] [0] INSIDE函数然后调用该函数并且它不会显示任何内容。

Answer 1

如果您将$t1定义为不在全局范围内，则会发生这种情况。在定义变量后立即执行$GLOBALS['t1'] = $t1;，尝试将其明确地放入全局变量中。

Answer 2

extract($t1);

尝试使用此功能而非全局。

更好的想法是将数组作为参数传递......

function seasonHistory($array){

$t1 = $array;

//your function
}

PHP数组在函数中不起作用
