私はここで論理的な問題に直面しているだけだと確信しています。
私はこのような配列を持っています:
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] =>
)
)
)
)
)
)
inf:name指定された名前に一致するときにいくつかのキーを削除したいと思います。
ここに私のテスト関数があります:
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( $myarray, array("aaa", "peter", "ccc") );
必要な出力は次のとおりです。
var_dump($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] =>
)
)
)
)
$newarrayキーをリセットする必要があります。リセットしないと、後で他の問題に直面する可能性があるためです。
君たちありがとう。
