Question

发布数组后，我能够print_r显示整个数组，但我无法回显单个值。我需要获取这些单个值，以便我可以将它们放在文本项的值标记中。目前，每次发布页面时，这些值都会消失，因为我找不到如何获取相应的值。

当我print_r（$ subs）时，我得到了正确的值 -

Array
(
    [0] => Array
        (
            ['subs_name'] => Image PC and load programs
            ['subs_target'] => 03/10/2015
            ['subs_owner'] => 1
        )

    [1] => Array
        (
            ['subs_name'] => Update Inventory
            ['subs_target'] => 03/17/2015
            ['subs_owner'] => 1
        )

    [2] => Array
        (
            ['subs_name'] => Deploy PC
            ['subs_target'] => 03/24/2015
            ['subs_owner'] => 1
        )

    [3] => Array
        (
            ['subs_name'] => Follow up with user
            ['subs_target'] => 03/31/2015
            ['subs_owner'] => 1
        )

)

如果我试图回复$ subs [0] [＆＃39; subs_target＆＃39;]我没有得到任何回报。我确定我做了一些愚蠢的事，但我无法确定那是什么。我扫描了几篇文章并找不到解决方案。

这是我用来设置数组的表单输入 -

    while ($row = $stmt->fetch()) {
        echo "                  <tr>\n";
        echo "                      <td>\n";
        echo "<input type=\"hidden\" name=\"subs[$count]['subs_name']\" class=\"none\" value=\"" . $row['prosub_name'] . "\">";
        echo "<p>" . $row['prosub_name'] . "</p>";
        echo "</td>\n";
        echo "                      <td align=\"center\">\n";
        echo "                          <input type=\"text\" class=\"datepicker\" name=\"subs[$count]['subs_target']\" value=\"" . $subs["$count"]['subs_target'] . "\">\n"; 
        echo "</td>\n";
        echo "                      <td align=\"center\">\n";
        echo "                          <select name=\"subs[$count]['subs_owner']\" class=\"diedit\">\n"; 
        getUserDD($hid_owner, 'acc_tix_pro');
        echo "                          </select>\n"; 
        echo "                      </td>\n";
        echo "                  </tr>\n";
        $count++;
    }

尝试使用echo检查值，但使用var_dump：

 var_dump($subs[0]['subs_target']);

php - 可以打印多维数组，但不能回显单值
