Php 斯芬克斯返回数组和权重。

我试图简单地回应返回的重量，并做了一些非常错误的事情

   [matches] => Array
     (
        [34] => Array
            (
                [weight] => 1707
                [attrs] => Array
                    (
                    )

            )

    )

以下是返回的数据示例： 排列 ( [错误]=> [警告]=> [状态]=>0 [字段]=>数组 ( [0]=>短语 ) [attrs]=>数组 ( )

   [matches] => Array
     (
        [34] => Array
            (
                [weight] => 1707
                [attrs] => Array
                    (
                    )

            )

    )

这是获取id的工作代码。这对我来说很有意义

   [matches] => Array
     (
        [34] => Array
            (
                [weight] => 1707
                [attrs] => Array
                    (
                    )

            )

    )

      if ( ! empty($result["matches"]) ) {
      foreach ( $result["matches"] as $doc => $docinfo ) {
            echo "DOC ID:$doc\n";
      }

      print_r( $result );
  }

我尝试了另一个foreach，使用doc id循环并获取重量

   [matches] => Array
     (
        [34] => Array
            (
                [weight] => 1707
                [attrs] => Array
                    (
                    )

            )

    )

foreach $doc as $weight  {

这不管用。我猜我在多维数组中做错了什么，但我不确定如何处理嵌套数组

   [matches] => Array
     (
        [34] => Array
            (
                [weight] => 1707
                [attrs] => Array
                    (
                    )

            )

    )

谢谢

您必须尝试递归函数

   [matches] => Array
     (
        [34] => Array
            (
                [weight] => 1707
                [attrs] => Array
                    (
                    )

            )

    )

$array =array(
    "matches" => array(
        array("weight"=>1707,"attrs"=>array("weight"=>100)),
        array("weight"=>1700,"attrs"=>array("weight"=>170)),
        array("weight"=>10,"attrs"=>array("weight"=>170,"attr"=>array("weight"=>"something other")))
    )
);

function recurse($array){
    foreach ($array as $arr){
        if (is_array($arr)){
            recurse($arr);
        } else {
            echo $arr . "<br>";
        }
    }
}

recurse($array);

是否要从多级数组返回

weight

参数？否。数据结构在那里。我只是想得到1707的值。
