如何获得这样的数组？

Question

我有一个PHP数组是这样的：

Array 
(
    [0] => Array 
    (
     [name] => abc 
     [id] => 107    
     [CycleNumber] => 1 
     [Type] => People 
    ) 
    [1] => Array 
    (
     [name] => john 
     [id] => 312   
     [CycleNumber] => 5 
     [Type] => People 
    ) 
    [2] => Array 
    (
     [name] => jenny 
     [id] => 110   
     [CycleNumber] => 3 
     [Type] => People 
    ) 
    [3] => Array 
    (
     [name] => metting room 
     [id] => 590 
     [CycleNumber] => 4 
     [Type] => Facility 
    ) 
    [4] => Array 
    (
     [name] => projector 
     [id] => 470  
     [CycleNumber] => 4 
     [Type] => Facility 
    ) 

) 

我想用空白来代替重复的类型。但第一个应该有这个类型的名称，其他的应该是空白的。所以结果数组应该是这样的：

Array 
(
    [0] => Array 
    (
     [name] => abc 
     [id] => 107    
     [CycleNumber] => 1 
     [Type] => People 
    ) 
    [1] => Array 
    (
     [name] => john 
     [id] => 312   
     [CycleNumber] => 5 
     [Type] => 
    ) 
    [2] => Array 
    (
     [name] => jenny 
     [id] => 110   
     [CycleNumber] => 3 
     [Type] => 
    ) 
    [3] => Array 
    (
     [name] => metting room 
     [id] => 590 
     [CycleNumber] => 4 
     [Type] => Facility 
    ) 
    [4] => Array 
    (
     [name] => projector 
     [id] => 470  
     [CycleNumber] => 4 
     [Type] => 
    ) 

) 

我只想要这种格式的数组。我正在使用PHP zend。

我搜索这个，但其中大部分显示从数组中删除该元素。但我不想删除它。我想用空白替换它，但想显示第一个。

试过代码

$result = array(); 
$result1 = array(); 
$result2 = array(); 
$y = array(); 
$y1 = array(); 
foreach ($data as $entry) { 
    $type= $entry["type"]; 
    if (!isset($y[$type])) { 
     $y[$type] = array(); 
     unset($entry["type"]); 
     $result[$type][] = $entry; 
    } 
} 

谁能告诉我该怎么做？

代码

$i = 0; 
$found = 0; 
foreach($data as $key=>&$val) { 
if($i != 0) { 
    if($data[$i]['Type'] == $data[$found]['Type']) { 
     $data[$i]['Type'] = ""; 
    } 
    else { 
     $found = $i; 
    } 
} 
$i++; 
} 
echo "<pre>"; 
print_r($data); 

输出

Array 
(
[0] => Array 
    (
     [name] => abc 
     [id] => 107 
     [CycleNumber] => 1 
     [Type] => People 
    ) 

[1] => Array 
    (
     [name] => john 
     [id] => 312 
     [CycleNumber] => 5 
     [Type] => 
    ) 

[2] => Array 
    (
     [name] => jenny 
     [id] => 110 
     [CycleNumber] => 3 
     [Type] => 
    ) 

[3] => Array 
    (
     [name] => metting room 
     [id] => 590 
     [CycleNumber] => 4 
     [Type] => Facility 
    ) 

[4] => Array 
    (
     [name] => projector 
     [id] => 470 
     [CycleNumber] => 4 
     [Type] => 
    ) 

)
