php - 以可读/分层格式显示数组

Question

这是为我的数组提取数据的代码

<?php
    $link = mysqli_connect('localhost', 'root', '', 'mutli_page_form');

    $query = "SELECT * FROM wills_children WHERE will=73";

    $result = mysqli_query($link, $query) or die(mysqli_error($link));

    if ($result = mysqli_query($link, $query)) {

    /* fetch associative array */
    if($row = mysqli_fetch_assoc($result)) {
        $data = unserialize($row['children']);
    }

    /* free result set */
    mysqli_free_result($result);
    }
?>

当我使用 print_r($data) 时，它显示为:

Array ( [0] => Array ( [0] => Natural Chlid 1 [1] => Natural Chlid 2 [2] => Natural Chlid 3 ) ) 

我希望它读作:

自然 child 1
亲生 child 2
亲生 child 3

Answer 1

代替

print_r($data);

试试

print "<pre>";
print_r($data);
print "</pre>";
