PHP數群組轉換

源數組：

$attributes = array(    'Users' => array(        'Name' => 'Name',    ),    'Address' => 'Address',    'Tags' => array(        0 => array(            'Key' => 'Key',            'Value' => 'Value',        ),        1 => array(            'Key' => 'Key',        ),        2 => array(        )    ),);

希望轉換為如下數組：

$result = array(    'Users_Name' => 'Name',    'Address' => 'Address',    'Tags_0_Key' => 'Key',    'Tags_0_Value' => 'Value',    'Tags_1_Key' => 'Key',    // 'Tags_2' => '',);

遞迴方式嘗試了半天，依然沒有解決，如何轉換呢？

如果那個空數組也要轉換的話自己再分個類就好啦。

 $val ) {        $key = array_merge( $prefix, array($key) );        if( is_array($val) ) $res = array_merge( $res, transfer( $val, $key, $glue ) );        else $res[ implode($glue, $key) ] = $val;    }    return $res;}$attributes = array(    'Users' => array(        'Name' => 'Name',    ),    'Address' => 'Address',    'Tags' => array(        0 => array(            'Key' => 'Key',            'Value' => 'Value',        ),        1 => array(            'Key' => 'Key',        ),        2 => array(        )    ),);var_dump( transfer( $attributes ) );
