Question

我正在尝试将两个php变量插入到数组中但没有成功。我能够让它与一个变量一起工作，但是一旦我打破了它。下面是我正在使用的代码示例。

$gapi_primary_dimension = get_option('gapi_primary_dimension');
$gapi_secondary_dimension = get_option('gapi_secondary_dimension'); 

if($gapi_primary_dimension <> "" && $gapi_secondary_dimension <> ""){
  $array = array(
        'dimensions'  => 'ga:'.$gapi_primary_dimension,'ga:'.$gapi_secondary_dimension,
        'sort'        => 'ga:sessions',
        'max-results' => 5
  );
} elseif($gapi_primary_dimension <> ""){
  $array = array(
        'dimensions'  => 'ga:'.$gapi_primary_dimension,
        'sort'        => 'ga:sessions',
        'max-results' => 5
  );    
} else {
    $array = array(
        'dimensions'  => 'ga:channelGrouping',
        'sort'        => 'ga:sessions',
        'max-results' => 5      
    );   
}

错误具体在这一行

'dimensions'  => 'ga:'.$gapi_primary_dimension,'ga:'.$gapi_secondary_dimension,

任何帮助都将不胜感激。

Answer 1

使用类似的东西

$matrix= array();
$matrix[1]= 'element 1';
$matrix[2]= 'element 2';

Answer 2

试试这个：

'dimensions'  => 'ga:' . $gapi_primary_dimension . ', ga:' . $gapi_secondary_dimension,

Answer 3

感谢@Ghost

'dimensions'  => 'ga:' . $gapi_primary_dimension . ', ga:' . $gapi_secondary_dimension,
