我从wordpress中的数据库中获取此值

如何在php中获取这些值？

您需要取消meta_值的序列化，它将以嵌套数组的形式输出值

$value is the meta_value you are getting from executing the database query.

$asdf = unserialize ($value);
echo "<pre>"; print_r($asdf);

---

之后，可以使用数组索引获取值-

echo$asdf[0]['name']；//它将打印名称

或者使用嵌套数组格式

foreach（$asdf作为$qwer）
{ 
if（is_数组（$qwer））{
foreach（$qwer作为$value）{
echo”“；print_r（$value）；
}
}
}

它对我有用，希望对我有所帮助。

在wordpress中获取元数据有一个功能

Array
(
[0] => Array
    (
        [mode] => builder
        [name] => Service Dog Handler Name *
        [value] => handler name
        [price] => 0
        [section] => 555453917016c5.41306136
        [section_label] => Service Dog Handler Name *
        [percentcurrenttotal] => 0
        [quantity] => 1
    )

[1] => Array
    (
        [mode] => builder
        [name] => Service Dog Name *
        [value] => dog name
        [price] => 0
        [section] => 55545e36c8cbd4.93742171
        [section_label] => Service Dog Name *
        [percentcurrenttotal] => 0
        [quantity] => 1
    )

foreach($asdf as $qwer) 
   { 
     if (is_array($qwer)){
    foreach ($qwer as $value) {
        echo "<pre>"; print_r($value);
    }
}
}
