你把数组弄成多行，就能一眼看出数组的结构，我整理如下：

array(1) {
  ["data"]=> array(6) {
    [0]=> array(7) {
      ["id"]=> string(1) "4"
      ["pid"]=> string(1) "6"
      ["danbaofang"]=> string(4) "个人"
      ["danbao1name"]=> string(4) "测试"
      ["danbao1haoma"]=> string(4) "测试"
      ["nativeplace"]=> string(4) "测试"
      ["danbao1tel"]=> string(4) "测试"
    }
    [1]=> array(7) {
      ["id"]=> string(1) "5"
      ["pid"]=> string(1) "6"
      ["danbaofang"]=> string(4) "个人"
      ["danbao1name"]=> string(4) "测试"
      ["danbao1haoma"]=> string(4) "测试"
      ["nativeplace"]=> string(4) "测试"
      ["danbao1tel"]=> string(4) "测试"
    }
    [2]=> array(7) {
      ["id"]=> string(1) "6"
      ["pid"]=> string(1) "6"
      ["danbaofang"]=> string(4) "个人"
      ["danbao1name"]=> string(4) "测试"
      ["danbao1haoma"]=> string(4) "测试"
      ["nativeplace"]=> string(4) "测试"
      ["danbao1tel"]=> string(4) "测试" }
      [3]=> array(7) {
      ["id"]=> string(1) "7"
      ["pid"]=> string(1) "6"
      ["danbaofang"]=> string(4) "个人"
      ["danbao1name"]=> string(4) "测试"
      ["danbao1haoma"]=> string(4) "测试"
      ["nativeplace"]=> string(4) "测试"
      ["danbao1tel"]=> string(5) "0测试"
      }
    [4]=> array(7) {
      ["id"]=> string(1) "8"
      ["pid"]=> string(1) "6"
      ["danbaofang"]=> string(4) "个人"
      ["danbao1name"]=> string(4) "测试"
      ["danbao1haoma"]=> string(4) "测试"
      ["nativeplace"]=> string(4) "测试"
      ["danbao1tel"]=> string(4) "测试"
      }
    [5]=> array(7) {
      ["id"]=> string(1) "9"
      ["pid"]=> string(1) "6"
      ["danbaofang"]=> string(4) "个人"
      ["danbao1name"]=> string(4) "测试"
      ["danbao1haoma"]=> string(4) "测试"
      ["nativeplace"]=> string(4) "测试"
      ["danbao1tel"]=> string(4) "测试"
    }
  }
}

现在是不是觉得很简单了，可以使用foreach和join输出，例如（加上你的数组是$arr）：

echo '<table>';
foreach ($arr['data'] as $tr){
echo '<tr><td>' . implode('<td>', $tr);
}
echo '</table>';

追问那么假如以上数组我是存在变量$users中！您的代码我改如何改呢！新手请见谅！

追答只改一个地方：第2行的arr三个字母修改为users五个字母。

foreach（$user['data'] as $v）{

$str.="<td>".$v['id']."</td><td>".$v['pid']."</td>......";//自己补完
}
