基于另一个数组的排序数组

Question

我想根据第一个数组对第二个数组($array2)进行排序($field‘second )

$field_name = "field_52f8fcdd21cb6";
$field = get_field_object($field_name);

foreach( $field['choices'] as $k=>$v) {
    echo $k."==".$v."<br>";
}

上面的代码提供了以下输出

Gyana Yagna==Gyana Yagna
Festival==Festival
Retreat==Retreat
Performance==Performance
Swaranjali==Swaranjali

现在，第二个数组启动。

echo "<br><br><br>";
$array2 = array("Gyana Yagna","Gyana Yagna","Gyana Yagna","Retreat","Festival","Festival");

foreach( $array2 as $k=>$v)
{
    if(in_array($v,$field['choices']))
    {
        echo $array2[$k]."<br>";
    }
    else
    {
        echo $array2[$k+1]."<br>";
    }
}

期望的输出应该是

Gyana Yagna
Gyana Yagna
Gyana Yagna
Festival
Festival
Retreat

而我得到的输出如下

Gyana Yagna
Gyana Yagna
Gyana Yagna
Retreat
Festival
Festival

任何帮助都是非常感谢的。提前谢谢。

Answer 1

以下是基于我的评论的解决方案：

$field['choices']= array('Gyana Yagna', 'Festival', 'Retreat');


echo "<br><br><br>";
$array2 = array("Gyana Yagna","Gyana Yagna","Gyana Yagna","Retreat","Festival","Festival");

foreach( $field['choices'] as $k=>$v)
{
foreach($array2 as $k2=>$v2){
    if($v==$v2)
      {
          echo $array2[$k2]."<br>";
      }
}

}

输出与您想要的输出相同。
