Question

我在第9行和第19行),和);上收到了偏移错误，但我不确定原因。我不认为我在我的阵列上调用一个对象，因为$ i和$ j都是数字。这都是为了在btw表格中显示图像。提前谢谢！

代码：

            $hero = Array (
            [0] => Array

使用[0] =＆gt;数组（...）正在尝试将数组定义为键。键可以是字母数字，如关联数组或数字索引数组。

因此，您可以让数组决定数字索引，因为您从0开始。

$hero = array(
    array
    (
        array("Superman", "<img src='https://upload.wikimedia.org/wikipedia/en/e/eb/SupermanRoss.png' alt='Superman' title='Superman' style='height:150px;'>", 1),
        array("Batman", "<img src='https://img00.deviantart.net/d9fa/i/2017/079/7/d/batman___transparent_by_asthonx1-db2yliv.png' alt='Batman' title='Batman' style='height:150px;'>", 1),
        array("Flash", "<img src='http://www.pngmart.com/files/2/Flash-Transparent-PNG.png' alt='Flash' title='Flash' style='height:150px;'>", 1),
        array("Aquaman", "<img src='https://vignette.wikia.nocookie.net/deathbattle/images/8/8f/Aquaman_transparent_by_asthonx1-dakip9a.png/revision/latest?cb=20170702181517' alt='Aquaman' title='Aquaman' style='height:150px;'>", 1),
        array("Green Lantern", "<img src='https://orig00.deviantart.net/d594/f/2017/197/4/d/green_lantern_request___transparent_background_by_camo_flauge-dbgi25l.png' alt='Green Lantern' title='Green Lantern' style='height:150px;'>", 1)
    ),
    array
    (
        array("Wolverine", "<img src='https://orig00.deviantart.net/4580/f/2016/274/1/f/wolverine___transparent_by_asthonx1-dajhanh.png' alt='Wolverine' title='Wolverine' style='height:150px;'>", 2),
        array("Ironman", "<img src='http://www.pngmart.com/files/3/Iron-Man-PNG-File.png' alt='Ironman' title='Ironman' style='height:150px;'>", 2),
        array("Ant Man", "<img src='https://orig00.deviantart.net/7ec8/f/2016/092/d/f/ant_man_by_cptcommunist-d9xiez4.png' alt='Ant man' title='Ant man' style='height:150px;'>", 2),
        array("Thor", "<img src='http://www.freepngimg.com/download/thor/3-2-thor-transparent.png' alt='Thor' title='Thor' style='height:150px;'>", 2),
        array("Hulk", "<img src='https://img00.deviantart.net/f71e/i/2016/274/7/8/hulk___transparent_by_asthonx1-dajha0a.png' alt='Hulk' title='Hulk' style='height:150px;'>", 2)
    ),
);

或者您可以更明确地定义初始外部数组索引（如关联数组）并使用...

$hero = array(
    0 => array
    (
        array("Superman", "<img src='https://upload.wikimedia.org/wikipedia/en/e/eb/SupermanRoss.png' alt='Superman' title='Superman' style='height:150px;'>", 1),
        array("Batman", "<img src='https://img00.deviantart.net/d9fa/i/2017/079/7/d/batman___transparent_by_asthonx1-db2yliv.png' alt='Batman' title='Batman' style='height:150px;'>", 1),
        array("Flash", "<img src='http://www.pngmart.com/files/2/Flash-Transparent-PNG.png' alt='Flash' title='Flash' style='height:150px;'>", 1),
        array("Aquaman", "<img src='https://vignette.wikia.nocookie.net/deathbattle/images/8/8f/Aquaman_transparent_by_asthonx1-dakip9a.png/revision/latest?cb=20170702181517' alt='Aquaman' title='Aquaman' style='height:150px;'>", 1),
        array("Green Lantern", "<img src='https://orig00.deviantart.net/d594/f/2017/197/4/d/green_lantern_request___transparent_background_by_camo_flauge-dbgi25l.png' alt='Green Lantern' title='Green Lantern' style='height:150px;'>", 1)
    ),
    1 => array
    (
        array("Wolverine", "<img src='https://orig00.deviantart.net/4580/f/2016/274/1/f/wolverine___transparent_by_asthonx1-dajhanh.png' alt='Wolverine' title='Wolverine' style='height:150px;'>", 2),
        array("Ironman", "<img src='http://www.pngmart.com/files/3/Iron-Man-PNG-File.png' alt='Ironman' title='Ironman' style='height:150px;'>", 2),
        array("Ant Man", "<img src='https://orig00.deviantart.net/7ec8/f/2016/092/d/f/ant_man_by_cptcommunist-d9xiez4.png' alt='Ant man' title='Ant man' style='height:150px;'>", 2),
        array("Thor", "<img src='http://www.freepngimg.com/download/thor/3-2-thor-transparent.png' alt='Thor' title='Thor' style='height:150px;'>", 2),
        array("Hulk", "<img src='https://img00.deviantart.net/f71e/i/2016/274/7/8/hulk___transparent_by_asthonx1-dajha0a.png' alt='Hulk' title='Hulk' style='height:150px;'>", 2)
    )

);

Answer 2

这可能是由于众多事情造成的。由于您没有提供任何错误，我只能分析您所提供的内容。

1，
你的$ hero是一个包含2个数组的数组，它们保存数组。确保您正确访问这些内容。

2，
确保$ _POST [＆＃39;战斗＆＃39;]被设置。你不能依赖它被设定甚至是真或假。始终检查外部（和内部）输入。

3，
这条线： var_dump($array); 是错的。你有英雄数组，因为$ i和英雄数组的部分为$ j。但是，这不会访问任何超级英雄，因为您没有引用任何超级英雄。该错误可能来自于尝试定期打印阵列。如果您要打印包含<pre>或<code>标签的数组{{1}}，建议您使用。
