多维解释();制表符分隔的序列数组键字符串

Question

我正在Drupal中处理一个视图，并得到了如下字符串：

Room:  Bedroom Length:  5.00 Width:  5.00 Area:  25.00 Room:  Bathroom Length:  3.00 Width:  3.00 Area:  9.00 

这是针对两个"房间"对象，每个对象都有长度、宽度和面积。

我该如何将其分解为如下多维数组：

array( [0] => array( [room] => "Bedroom" [length] => "5.00" [width] => "5.00" [area] => "25.00")
       [1] => array( [room] => "Bathroom" [length] => "3.00" [width] => "3.00" [area] => "9.00"))

如您所知，第一步是将字符串放入一个变量中，以便能够使用它。然后，您可以在"Room"上拆分字符串，但我将继续这个示例，就好像每个$spec都有两个房间一样。

//need the string in a variable ....  
$specs = "Room:  Bedroom Length:  5.00 Width:  5.00 Area:  25.00 Room:  Bathroom Length:  3.00 Width:  3.00 Area:  9.00";
//Explode your string on space caracter:
$specs_exploded = explode(" ", $specs);
// Then,  call the following function to build your array: 
$specs_array = build_specs($specs_exploded);
// Function that builds and returns specs_array. 
function build_specs(Array $specs){
    $spec_array = array();  
    $spec_array[] = array("room"   => $specs[1], 
                          "length" => $specs[3],
                          "width"  => $specs[5], 
                           // you could also set the key programmaticaly...
                           // the following woud give you "Area" => 25.00
                          $specs[6] => $specs[7],
                          );
                     // Second room
    $spec_array[] = array("room"  => $specs[9],
                         // etc...
                         );
   return $spec_array;
}

请注意，示例功能仅处理2个房间。如果您有一个函数，用strpos（）将字符串拆分为"rooms"并返回一个rooms数组，情况会更好。

将返回的rooms数组传递给一次只处理一个房间的上述示例函数的版本。

希望这足以让你继续前进，祝你好运！
