如何在 PHP 中解析它：

a:8:{s:3:"key";s:19:"field_501743d4baa78";s:5:"label";s:8:"Category";s:4:"name";s:8:"category";s:4:"type";s:8:"checkbox";s:12:"instructions";s:0:"";s:8:"required";s:1:"1";s:7:"choices";a:17:{s:4:"Arts";s:4:"Arts";s:8:"Business";s:8:"Business";s:14:"Communications";s:14:"Communications";s:16:"Criminal Justice";s:16:"Criminal Justice";s:13:"Culinary Arts";s:13:"Culinary Arts";s:9:"Education";s:9:"Education";s:11:"Engineering";s:11:"Engineering";s:11:"Health Care";s:11:"Health Care";s:22:"Information Technology";s:22:"Information Technology";s:13:"International";s:13:"International";s:5:"Legal";s:5:"Legal";s:17:"Political Science";s:17:"Political Science";s:10:"Psychology";s:10:"Psychology";s:8:"Religion";s:8:"Religion";s:7:"Science";s:7:"Science";s:9:"Technical";s:9:"Technical";s:10:"Veterinary";s:10:"Veterinary";}s:8:"order_no";s:1:"3";}

获取所有“类别”的列表，例如艺术、商业、通信等

谢谢你的帮助

运行反序列化后，这是我得到的：

array(8) { ["key"]=> string(19) "field_501743d4baa78" ["label"]=> string(8) "Category" ["name"]=> string(8) "category" ["type"]=> string(8) "checkbox" ["instructions"]=> string(0) "" ["required"]=> string(1) "1" ["choices"]=> array(17) { ["Arts"]=> string(4) "Arts" ["Business"]=> string(8) "Business" ["Communications"]=> string(14) "Communications" ["Criminal Justice"]=> string(16) "Criminal Justice" ["Culinary Arts"]=> string(13) "Culinary Arts" ["Education"]=> string(9) "Education" ["Engineering"]=> string(11) "Engineering" ["Health Care"]=> string(11) "Health Care" ["Information Technology"]=> string(22) "Information Technology" ["International"]=> string(13) "International" ["Legal"]=> string(5) "Legal" ["Political Science"]=> string(17) "Political Science" ["Psychology"]=> string(10) "Psychology" ["Religion"]=> string(8) "Religion" ["Science"]=> string(7) "Science" ["Technical"]=> string(9) "Technical" ["Veterinary"]=> string(10) "Veterinary" } ["order_no"]=> string(1) "3" }

但是我不确定如何循环并获取类别名称 - 抱歉 - 我是 PHP 新手 - 可能只是在做一些愚蠢的事情 - 感谢您的帮助

那只是一个序列化的数组。只需反序列化它并轻松获取值：

$array = unserialize(a:8:{s:3:"key";s:19:"field_501743d4baa78";s:5:"label";s:8:"Category";s:4:"name";s:8:"category";s:4:"type";s:8:"checkbox";s:12:"instructions";s:0:"";s:8:"required";s:1:"1";s:7:"choices";a:17:{s:4:"Arts";s:4:"Arts";s:8:"Business";s:8:"Business";s:14:"Communications";s:14:"Communications";s:16:"Criminal Justice";s:16:"Criminal Justice";s:13:"Culinary Arts";s:13:"Culinary Arts";s:9:"Education";s:9:"Education";s:11:"Engineering";s:11:"Engineering";s:11:"Health Care";s:11:"Health Care";s:22:"Information Technology";s:22:"Information Technology";s:13:"International";s:13:"International";s:5:"Legal";s:5:"Legal";s:17:"Political Science";s:17:"Political Science";s:10:"Psychology";s:10:"Psychology";s:8:"Religion";s:8:"Religion";s:7:"Science";s:7:"Science";s:9:"Technical";s:9:"Technical";s:10:"Veterinary";s:10:"Veterinary";}s:8:"order_no";s:1:"3";});
var_dump($array);

$sample_arr = unserialize($array); //unserialize here
$sample_arr = $sample_arr['choices']; //get the array

然后您将类别列表保存到 $sample_arr。

foreach($sample_arr as $temp) {
  //do stuff with each element here
}

示例包括将其输出为 html 列表

echo '<ul>';
foreach($sample_arr as $temp) {
  echo '<li>' . $temp . '</li>';
}
echo '</ul>';
