PHP Array Looping problem

$arr = Array (    ' group ' = 0, ' name ' = ' guest test1 ', ' sort ' = 0), 1 = = Array (    ' group ' = 1, ' name ' = ' guest test2 ', ' sort ' and ' = 1 ',    2 = = Array (' group ' = + 1, ' name ' = ' guest ' test3 ', ' sort ' = ' 2 '), 
  3 = = Array (' group ' = 0, ' name ' = ' guest test4 ', ' sort ' = ' = 3 '),    4 = = Array (' group ' = 2, ' name ' = = ' Guest test5 ', ' sort ' and ' 4 ',    5 = = Array (' group ' = 2, ' name ' = ' guest ' Test6 ', ' sort ' = 5),    );

The original array, like above, wants the loop to get the following result:

$rs = Array (        ' group ' = 0, ' name ' = ' guest test1 ', ' sort ' = 0),    ' group_1 ' = = Array (
  array (' group ' = 1, ' name ' = ' guest test2 ', ' sort ' and ' = 1 '),    Array (' group ' = 1, ' name ' = ' guest ' test3 ', ' sort ' = 2 '),    3 = = Array (' group ' = 0, ' name ' = ' guest test4 ', ' sort ' = = 3),    ' group_2 ' = = Array ( C8/>array (' group ' = 2, ' name ' = ' guest test5 ', ' sort ' and ' = 4 '),    Array (' group ' = 2, ' name ' = ' guest ' Test6 ', ' so RT ' = 5),    )    );

Can be extracted from the group, while preserving the sort, I always can't write, please God Help

 $arr = Array (0 = = Array (' group ' = + 0, ' name ' = ' guest test1 ', ' sort ' = 0), 1 = = Array (' group ' = 1, ' name ' = ' guest test2 ', ' sort ' = ' = 1 '), 2 = = Array (' group ' + 1, ' name ' = ' guest ' test  3 ', ' sort ' and ' = 2 ', 3 = = Array (' group ' + 0, ' name ' = ' guest test4 ', ' sort ' = 3), 4-= array (' Group ' = 2, ' name ' = ' guest test5 ', ' sort ' and ' = 4 ', 5 = = Array (' group ' = + 2, ' name ' = ' guest ' Test6 ', ' sort ' = ' 5 '); for    Each ($arr as $k + $v) {if ($v [' group '] = = 0) {$g = $k;  $res [$g] = $v; }else $res [$g] [' group_1 '] [] = $v;} Print_r ($res); 

Array ([0] = = Array ([group] = 0 [name] + guest Test1 [sort] = 0                            [Group_1] = = Array ([0] = = Array (                        [Group] = 1 [name] + guest Test2 [sort] + 1  ) [1] = = Array ([Group] = =                1 [name] + guest Test3 [sort] + 2) )) [3] = = Array ([group] = 0 [Name] = Guest Test4 [s                             ORT] = 3 [group_1] = = Array ([0] = = Array ( [Group] = 2 [name] + guest TEST5 [so             RT] = 4           ) [1] = = Array ([Group] = 2                [Name] + guest Test6 [sort] = 5) )        ))

$arr = Array (            ' group ' = 0, ' name ' = ' guest test1 ', ' sort ' = 0), 1 = = Array (            ' group ' = 1, ' name ' = ' guest test2 ', ' sort ' and ' = 1 ',            2 = = Array (' group ' = + 1, ' name ' = ' guest ' test3 ', ' sort ' = ' 2 '), 
  3 = = Array (' group ' = 0, ' name ' = ' guest test4 ', ' sort ' = ' = 3 '),            4 = = Array (' group ' = 2, ' name ' = = ' Guest test5 ', ' sort ' and ' 4 ',            5 = = Array (' group ' = 2, ' name ' = ' guest Test6 ', ' sort ' = ' 5 '),        $data = Arra Y (), foreach ($arr as $key = + $val) {if ($val [' Group ']==0) {$tmp = $key; $data [$tmp] = $val;} else{$data [$tmp] [' group_ '. $val [' group ']][] = $val;}} Print_r ($data);

May not be clear, I want the result is as follows, upstairs 2 people gave the result is not this

Array ([0] = = Array ([group] = 0 [name] + guest Test1 [sort] = 0                    ) [Group_1] = = Array ([0] = = Array ([Group] = 1                [Name] + guest Test2 [sort] = 1) [1] = = Array                ([Group] = 1 [name] + guest Test3 [sort] + 2            )) [3] = = Array ([group] = 0 [name] + guest TEST4 [Sort] = 3) [group_2] = = Array ([0] = = Array ([ Group] = 2 [name] + guest Test5 [sort] = 4) [1] =                    > Array ([Group] = 2 [name] + guest TEST6          [Sort] = 5      )        )) 

$arr = Array (            ' group ' = 0, ' name ' = ' guest test1 ', ' sort ' = 0), 1 = = Array (            ' group ' = 1, ' name ' = ' guest test2 ', ' sort ' and ' = 1 ',            2 = = Array (' group ' = + 1, ' name ' = ' guest ' test3 ', ' sort ' = ' 2 '), 
  3 = = Array (' group ' = 0, ' name ' = ' guest test4 ', ' sort ' = ' = 3 '),            4 = = Array (' group ' = 2, ' name ' = = ' Guest test5 ', ' sort ' and ' 4 ',            5 = = Array (' group ' = 2, ' name ' = ' guest Test6 ', ' sort ' = ' 5 '),        $data = Arra Y (), foreach ($arr as $k = + $v) {if ($v [' Group ']==0) {$data [$k] = $v;} else{$data [' Group_ '. $v [' group ']][] = $v;}} Print_r ($data);

$arr = Array (            ' group ' = 0, ' name ' = ' guest test1 ', ' sort ' = 0), 1 = = Array (            ' group ' = 1, ' name ' = ' guest test2 ', ' sort ' and ' = 1 ',            2 = = Array (' group ' = + 1, ' name ' = ' guest ' test3 ', ' sort ' = ' 2 '), 
  3 = = Array (' group ' = 0, ' name ' = ' guest test4 ', ' sort ' = ' = 3 '),            4 = = Array (' group ' = 2, ' name ' = = ' Guest test5 ', ' sort ' and ' 4 ',            5 = = Array (' group ' = 2, ' name ' = ' guest Test6 ', ' sort ' = ' 5 '),        $data = Arra Y (), foreach ($arr as $k = + $v) {if ($v [' Group ']==0) {$data [$k] = $v;} else{$data [' Group_ '. $v [' group ']][] = $v;}} Print_r ($data);

Thank you so much
