我確信我只在這裏面臨一個邏輯問題。當某些特定值與給定數組匹配時，從多維數組中刪除密鑰
我有一個這樣的數組：
var_export($myarray);
array (
0 =>
array (
'inf:name' => 'aaa',
'inf:value' => '111',
'inf:children' => NULL,
),
1 =>
array (
'inf:name' => 'bbb',
'inf:value' => '222',
'inf:children' => NULL,
),
2 =>
array (
'inf:name' => 'ccc',
'inf:value' => '333',
'inf:children' => NULL,
),
3 =>
array (
'inf:name' => 'bob',
'inf:children' =>
array (
0 =>
array (
'inf:name' => 'ddd',
'inf:value' => '444',
'inf:children' => NULL,
),
),
),
4 =>
array (
'inf:name' => 'data',
'inf:children' =>
array (
0 =>
array (
'inf:name' => 'eee',
'inf:value' => '555',
'inf:children' => NULL,
),
1 =>
array (
'inf:name' => 'steve',
'inf:value' => 'bar1',
'inf:children' => NULL,
),
2 =>
array (
'inf:name' => 'john',
'inf:value' => 'bar2',
'inf:children' => NULL,
),
3 =>
array (
'inf:name' => 'peter',
'inf:value' => 'bar3',
'inf:children' =>
array (
0 =>
array (
'inf:name' => 'fff',
'inf:value' => '666',
'inf:children' => NULL,
),
),
),
),
),
)
//Or using print_r()
print_r($myarray);
Array
(
[0] => Array
(
[inf:name] => aaa
[inf:value] => 111
[inf:children] =>
)
[1] => Array
(
[inf:name] => bbb
[inf:value] => 222
[inf:children] =>
)
[2] => Array
(
[inf:name] => ccc
[inf:value] => 333
[inf:children] =>
)
[3] => Array
(
[inf:name] => bob
[inf:children] => Array
(
[0] => Array
(
[inf:name] => ddd
[inf:value] => 444
[inf:children] =>
)
)
)
[4] => Array
(
[inf:name] => data
[inf:children] => Array
(
[0] => Array
(
[inf:name] => eee
[inf:value] => 555
[inf:children] =>
)
[1] => Array
(
[inf:name] => steve
[inf:value] => bar1
[inf:children] =>
)
[2] => Array
(
[inf:name] => john
[inf:value] => bar2
[inf:children] =>
)
[3] => Array
(
[inf:name] => peter
[inf:value] => bar3
[inf:children] => Array
(
[0] => Array
(
[inf:name] => fff
[inf:value] => 666
[inf:children] =>
)
)
)
)
)
)
我想刪除一些按鍵時inf:name給定的名稱匹配。
這是我的測試功能：
function array_cleanup($array, $todelete)
{
foreach($array as $key => $value)
{
if(is_array($value))
{
$array[$key] = array_cleanup($array[ $key ], $todelete);
} else {
if(sizeOf($todelete) > 0)
{
if (in_array($value[ 'inf:name' ], $todelete))
unset($array[ $key ]);
}
}
}
return $array;
}
$newarray = array_cleanup($myarray, array("aaa", "peter", "ccc"));
所需的輸出必須是：
var_dump($newarray);
array (
0 =>
array (
'inf:name' => 'bbb',
'inf:value' => '222',
'inf:children' => NULL,
),
2 =>
array (
'inf:name' => 'bob',
'inf:children' =>
array (
0 =>
array (
'inf:name' => 'ddd',
'inf:value' => '444',
'inf:children' => NULL,
),
),
),
4 =>
array (
'inf:name' => 'data',
'inf:children' =>
array (
0 =>
array (
'inf:name' => 'eee',
'inf:value' => '555',
'inf:children' => NULL,
),
1 =>
array (
'inf:name' => 'steve',
'inf:value' => 'bar1',
'inf:children' => NULL,
),
2 =>
array (
'inf:name' => 'john',
'inf:value' => 'bar2',
'inf:children' => NULL,
),
),
),
)
//or using print_r();
print_r($newarray);
Array
(
[1] => Array
(
[inf:name] => bbb
[inf:value] => 222
[inf:children] =>
)
[2] => Array
(
[inf:name] => bob
[inf:children] => Array
(
[0] => Array
(
[inf:name] => ddd
[inf:value] => 444
[inf:children] =>
)
)
)
[3] => Array
(
[inf:name] => data
[inf:children] => Array
(
[0] => Array
(
[inf:name] => eee
[inf:value] => 555
[inf:children] =>
)
[1] => Array
(
[inf:name] => steve
[inf:value] => bar1
[inf:children] =>
)
[2] => Array
(
[inf:name] => john
[inf:value] => bar2
[inf:children] =>
)
)
)
)
的$newarray鍵必須復位。因爲如果他們沒有重置，我可能會在以後遇到其他問題。
謝謝你們。
多少級可深了'INF：children'進行拼圖？ – thirtydot 2010-12-15 20:37:26
@stereofrog：檢查更新，@thirtydot：它不應該超過四個級別，但我相信該函數應該遞歸調用，以便它可以適應任何輸入。 – Cybrix 2010-12-15 20:56:59
是從xml數組？ – ajreal 2010-12-15 21:02:44
