php - PHP - 通过 Foreach 返回多维数组

Question

我试图从多维数组中返回一个值，但它似乎不起作用。

数组-

[players] => Array
    (
        [0] => Array
            (
                [player] => Necro
                [score] => 0
                [deaths] => 0
                [gq_name] => 
                [gq_kills] => 
                [gq_deaths] => 0
                [gq_score] => 0
                [gq_ping] => 
            )

    )

PHP Foreach

<?php  
$dayzplayers = $results["dayz"]["players"];
          foreach($dayzplayers as $k => $v) {
                  echo ' <b>'.$v["player"].'</b>';
              } ?>

Answer 1

['player'] 索引在键 SOH（标题开始）中似乎有一个不可见的控制字符

尝试echo ' <b>'.$v[chr(1) . "player"].'</b>';代替echo ' <b>'.$v["player"].'</b>';

Answer 2

如果数据是您在第一个清单中发布的数据，则应该可以：

foreach($dayzplayers as $player) {
    echo $player[chr(1).'player'];
}
