在带有 stdClass 子数组的 JSON 数组中搜索值

Question

此 JSON 片段是 WooCommerce 订单的一部分，从 APIv2 get_order() 函数中提取。 [meta] 包含客户选择的产品变体数据。

[meta] => Array ( [0] => stdClass Object ( [key] => pa_size [label] => Size [value] => Large ) [1] => stdClass Object ( [key] => pa_color [label] => Choose Color [value] => Black )

如何在 stdClass 对象中搜索特定 [key] 和 return 其对应的 [value]？

Answer 1

应该这样做：

foreach ($rows as $object) {
{
    $size  = $object->pa_size;
    $color = $object->pa_color;
    // more code
}

Answer 2

<?php
   $meta = array();   //Suppose that your array is $meta

   $your_key="pa_size"; // if you are trying to search for "pa_size"
   $your_value=""; // will retrun value "Large"

   foreach( $meta as $obj )
   {
        if( $obj->key == $your_key )
        {
            $your_value = $obj->value;
            break;
        }
   }

   echo $your_value; // will retrun value "Large"
?>
