在PHP多维关联数组中添加数组键
|
我在更新深度嵌套的多维php关联数组时遇到问题。
我基本上希望它为所有下面具有数组的数组元素添加和带有递增值的\'parent_id \'键。
例如我有下面的数组。
[root] =>
Array(\'child_1\' =>
Array(\'child1_grandchild_1\' => \'gchild1_value\',
\'child1_grandchild_2\' => Array(\'grandchild_1\' => \'gchildval1\',
\'grandchild_2 => \'gchildval2\',
\'grandchild_3\' => \'gchildval3\'),
\'child1_grandchild_3\' => \'gchild3_value\'),
\'child_2\', => Array(\'child2_grandchild_1\' => \'gchildval1\',
\'child2_grandchild_2\' => \'gchildval2\'),
\'child_3\' => \'child3_val\',
\'child_4\' => \'child4_val\'
);
[root] =>
Array( \'parent_id\' => 1
\'child_1\' =>
Array(\'child1_grandchild_1\' => \'gchild1_value\',
\'child1_grandchild_2\' => Array(\'parent_id\' => 2,
\'grandchild_1\' => \'gchildval1\',
\'grandchild_2 => \'gchildval2\',
\'grandchild_3\' => \'gchildval3\'),
\'child1_grandchild_3\' => \'gchild3_value\'),
\'child_2\', => Array(\'parent_id\' => 3,
\'child2_grandchild_1\' => \'gchildval1\',
\'child2_grandchild_2\' => \'gchildval2\'),
\'child_3\' => \'child3_val\',
\'child_4\' => \'child4_val\'
);
没有找到相关结果

$no = 1000; $no2 = 1; function addpid(&$item, $key) { global $no; global $no2; if(is_array($item)){ $item[\'parent_id\'] = $no; $no++; }else{ $no2++; $no=$no2*1000; } } $yourarray array_walk_recursive($yourarray, \'addpid\');
