PHP数组爆炸一个char

Question

这是我的数组：

array:4 [ 
    0 => "Family Deluxe for 4 Person x 1" 
    1 => "Studio Deluxe for 2 Person x 1" 
    2 => "Additional Adult x 2" 
    3 => "Additional Children x 2" 
] 

当我进入一个foreach循环去除x并获得数，我碰到下面的输出结果：

array:4 [ 
    0 => array:1 [ 
    "Family Delu" => "e for 4 Person " 
    ] 
    1 => array:1 [ 
    "Studio Delu" => "e for 2 Person " 
    ] 
    2 => array:1 [ 
    " Additional Adult " => " 2" 
    ] 
    3 => array:1 [ 
    " Additional Children" => " 2" 
    ] 
] 

问题是，字符串Deluxe中存在x字符，因此循环会在哪里启动explode()混淆。下面是我的代码foreach：

foreach($a as $s) { 
      list($size, $quantity) = explode('x', $s); 
      $data[] = array($size => $quantity); 
      $sumVariant += $quantity; 
     } 

我怎样才能得到explode()识别x与两侧的空间？谢谢！！

Answer 1

explode()的分隔符参数不一定是单个字符，它可以是任何字符串。因此，使用x，并用空格作为分隔符。

list($size, $quantity) = explode(' x ', $s); 

Answer 2

explode(" x ", $s);应该诀窍。或者你可以得到explode数组的最后一项。
