JavaScript and PHP one-dimensional arrays and two-dimensional arrays of mutual transfer

First, PHP:

1. One-dimensional to two-dimensional:
   A. Code:

   /*@desc：一维数组转二维数组@param data 需要转换的数组@param key 主键@return ret 转换后的数组*/function onetomore($data,$key){$ret = array();foreach($data as $v){    $arr = array();    foreach($v as $k1=>$v1){        if($k1 != $key){            $arr[$k1] = $v1;        }    }    $ret[$v[$key]][] = $arr;}return $ret;}

   B. Testing:

   $data = array(array(    ‘user_id‘ => 1,    ‘role_id‘ => 1,    ‘user_nick‘ => ‘a‘),array(    ‘user_id‘ => 2,    ‘role_id‘ => 1,    ‘user_nick‘ => ‘b‘),array(    ‘user_id‘ => 3,    ‘role_id‘ => 2,    ‘user_nick‘ => ‘c‘));$ret = onetomore($data,‘role_id‘);var_dump($ret);

   C. Output:

   array(2) {[1]=>array(2) {[0]=>array(2) {  ["user_id"]=>  int(1)  ["user_nick"]=>  string(1) "a"}[1]=>array(2) {  ["user_id"]=>  int(2)  ["user_nick"]=>  string(1) "b"}}[2]=>array(1) {[0]=>array(2) {  ["user_id"]=>  int(3)  ["user_nick"]=>  string(1) "c"}}}

2. Two-dimensional turn one-dimensional:
   A. Code:

   /*@desc：二维数组转一维数组@param data 需要转换的数组@param key 主键@return ret 转换后的数组*/function moretoone($data,$key){$ret = array();$count = 0;foreach($data as $k=>$v){    foreach($v as $v1){        $ret[$count] = $v1;        $ret[$count][$key] = $k;        $count ++;    }}return $ret;}

   B. Testing:

   $data = array(1 => array(    array(        "user_id" => 1,        "user_nick" => ‘a‘    ),    array(        "user_id" => 2,        "user_nick" => ‘b‘    )),2 => array(    array(        "user_id" => 3,        "user_nick" => ‘c‘    )));$ret = moretoone($data,‘role_id‘);var_dump($ret);

   C. Output:

   array(3) {[0]=>array(3) {["user_id"]=>int(1)["user_nick"]=>string(1) "a"["role_id"]=>int(1)}[1]=>array(3) {["user_id"]=>int(2)["user_nick"]=>string(1) "b"["role_id"]=>int(1)}[2]=>array(3) {["user_id"]=>int(3)["user_nick"]=>string(1) "c"["role_id"]=>int(2)}}

   Second, javascript:
4. one-dimensional to two-dimensional:
   A. Code:

    /* @desc: one-dimensional array to two-dimensional array @param data need to convert an array of @param key primary key @return ret converted array */function Onetomore (Data,key) {var ret = {}for (var i in data) {Ret[data[i][key]] = new Array ()}for (var i-data) {var arr = {} for (Var j in da Ta[i]) {if (J! = key) {Arr[j] = data[i][j]}} ret[data[i][key]].push (arr)}return Ret} 

   B. Test:

     var data = new Array ({' uesr_id ': 1, ' role_id ': 1, ' User_nick ': ' A ' }, {' uesr_id ': 2, ' role_id ': 1, ' User_nick ': ' B '}, {' uesr_id ': 3, ' role_id ': 2 , ' User_nick ': ' C '}) var ret = onetomore (data, ' role_id ') console.log (ret)  

   C. Output:

     {' 1 ': [{uesr_id:1, User_nick: ' A '}, {uesr_id:2, User_nick: ' B '}], ' 2 ': [{uesr_id:3, User_nick: ' C '}]}   

6. Two-dimensional turn one-dimensional:
   A. Code:

   /*@desc：二维数组转一维数组@param data 需要转换的数组@param key 主键@return ret 转换后的数组*/function moretoone(data,key){var ret = new Array()var count = 0for(var i in data){    ret[count] = {}    for(var j in data[i]){        ret[count] = data[i][j]        ret[count][key] = i        count ++    }}return ret}

   B. Testing:

   var data = {1:new Array(        {            ‘user_id‘:1,            ‘user_nick‘:‘a‘        },        {            ‘user_id‘:2,            ‘user_nick‘:‘b‘        }    ),2:new Array(        {            ‘user_id‘:3,            ‘user_nick‘:‘c‘        }    )}var ret = moretoone(data,‘role_id‘)console.log(ret)

   C. Output:

   [ { user_id: 1, user_nick: ‘a‘, role_id: ‘1‘ },{ user_id: 2, user_nick: ‘b‘, role_id: ‘1‘ },{ user_id: 3, user_nick: ‘c‘, role_id: ‘2‘ } ]
