Foreach循环多维数组

Question

我正在使用从第三方来源接收的多维数组，因此无法更改它的布局。它用于大学，我想循环模块名称而不是 ID。

使用这个foreach循环时

<?php echo "<ul>";
                foreach($array['Course']['Modules']['Module'] as $key => $value)
                {
                    foreach($value as $keys => $values)
                    {
                        echo "<li>";
                            foreach($values as $thirdkey => $thirdvalues)
                            {
                            echo $thirdvalues . " " ;
                            }
                        echo "</li>";
                }
                    }
                echo "</ul>"
            ?>

我得到以下内容很好，但我不需要模块 ID：

003646 T.I.G. WELDING ALUMINIMUM INTERMEDIATE
003644 T.I.G. WELDING STAINLESS STEEL INTERMEDIATE
003633 MIG WELDING INTERMEDIATE
003552 MANUAL METAL ARC WELDING INTERMEDIATE
000016 MOUNTING OF ABRASIVE WHEELS
003299 MACHINE TOOLS (WELDING)
000001 INDUCTION
000002 CAREER PLANNING AND JOB SEEKING SKILLS
000029 OXY-ACETYLENE CUTTING
003757 THEORY OF WELDING
000003 IN-COMPANY
000664 SAFEPASS

这是我的数组，谁能帮我 return 只是模块标题？？？数组

提前致谢:)

Answer 1

你不想尝试 $thirdvalues["Title"] 对吗？看起来一团糟，但我不明白为什么如果你让它打印它就不起作用。

也可以if( $key == "Title" ) echo $value

Answer 2

你可以直接指向它。

foreach($array['Course']['Modules']['Module'] as $key => $value) {
    echo "<li>{$value['@attributes']['Title']}</li>";
}

旁注：这很可能是一个 SimpleXML 对象，被送入 json encode/decode.

$array = json_decode(json_encode($xml), true); // actually don't need to do this one

我建议始终使用 SimpleXML，因为它已经能够获取所有这些值。
