如何在php中组合一个数组

输出打印此文件：

How to my array combine :
$visitor_tracvking_data = json_encode($array);
print_r($visitor_tracvking_data);

如何输出此类型：-

    array (size=6)
  0 => 
    array (size=2)
      'tracktitle' => string 'search_engine' (length=13)
      'direct' => string '261' (length=3)
  1 => 
    array (size=2)
      'tracktitle' => string 'search_engine' (length=13)
      'social_media' => string '3' (length=1)
  2 => 
    array (size=2)
      'tracktitle' => string 'search_engine' (length=13)
      'search' => string '3' (length=1)
  3 => 
    array (size=2)
      'tracktitle' => string 'browser' (length=7)
      'chrome' => string '168' (length=3)
  4 => 
    array (size=2)
      'tracktitle' => string 'browser' (length=7)
      'firefox' => string '68' (length=2)
  5 => 
    array (size=2)
      'tracktitle' => string 'browser' (length=7)
      'netscape' => string '31' (length=2)

只需在数组中循环并使用

tracktitle

key-

array (size=2)
  0 => 
    array (size=2)
      'tracktitle' => string 'search_engine' (length=13)
      'direct' => string '261' (length=3)
      'social_media' => string '3' (length=1)
      'search' => string '3' (length=1)
  1 => 
    array (size=2)
      'tracktitle' => string 'browser' (length=7)
      'chrome' => string '168' (length=3)
      'firefox' => string '68' (length=2)
      'netscape' => string '31' (length=2)

或者对于json编码的字符串-

$new = array();

foreach($array as $key_top => $value) {
    foreach($value as $key => $val) {
        $new[$value['tracktitle']][$key] = $val;
    }
}

return $new;

好。找个人来做那件事。或者将您的代码投入到您尝试的目的中？循环并使用array\u pushNot merge array。。。只有一个数组并解决此问题…@GaurangP

$new

将保留该数组。如果要返回该数组，请返回

$new

，对于json返回json\u encode（$new）。简单。我的输出：-如何输出此类型：在显示中。但您的输出在：-output print\rthis@GaurangP支票-。你想要的方式。只需两个新键，而不是

0

&

1

。让我们来看看。

return json_encode($new);
