Answer 1

您可以在php中使用foreach loop。

foreach($your_array['data'] as $element){
    echo $element['coupon_description']."<br />";
    echo $element['store']."<br />";
    .....
}

Answer 2

您可以通过执行以下操作来访问搜索到的值：

// retrieve the coupon description for the first element of your array
echo $array['data'][0]['coupon_description'];

Answer 3

如果在PHP（http://php.net/manual/en/function.print-r.php）中使用函数print_r，则可以返回变量的可读格式。此功能将准确显示您在问题中显示的内容。唯一的问题是HTML不会解析标签，新行和空格。但是如果您使用HTML标记<pre>，它就会这样做。

所以我实际上一直使用这段代码来调试变量。我实际上在PHPStorm中为它做了一个简短的调整，以便更快地进行调试：

echo '<pre>';
print_r($data);
echo '</pre>';
die("Debug in file " . __FILE__ . ':' . __LINE__);

所以如果$ data是array('hey', 'there', 'cool', 'kid', array('how', 'are', 'you'))，那么这将输出：

Array
(
    [0] => hey
    [1] => there
    [2] => cool
    [3] => kid
    [4] => Array
        (
            [0] => how
            [1] => are
            [2] => you
        )

)

Debug in file /var/www/vhosts/test.local/test.php:10

这不仅适用于数组。您可以在基本上所有变量上使用它。在解析来自API或其他返回非常长响应的系统的响应时，它非常有用。

Answer 4

以下是多维数组的示例：

$cars = array
  (
  array("Volvo",22,18),
  array("BMW",15,13),
  array("Saab",5,2),
  array("Land Rover",17,15)
  );

如果没有 foreach 循环，您可以像这样回显多维数组：

for ($row = 0; $row < 4; $row++) {
  echo "<p><b>Row number $row</b></p>";
  echo "<ul>";
  for ($col = 0; $col < 3; $col++) {
    echo "<li>".$cars[$row][$col]."</li>";
  }
  echo "</ul>";
}
