php - Set::combine Cakephp, creating multi dimensional array using single dimensional array -

i have array having multiple values same values array of same keys

eg.

array(    [0] => array(                   'name' => "bob",                   'age'  => 20,                   'marks'=> 50                )    [1] => array(                   'name' => "ryan",                   'age'  => 20,                   'marks'=> 57                )    [2] => array(                   'name' => "allen",                   'age'  => 23,                   'marks'=> 70                )    [3] => array(                   'name' => "duke",                   'age'  => 23,                   'marks'=> 67                )    [4] => array(                   'name' => "matt",                   'age'  => 24,                   'marks'=> 85                ) ) 

i want convert them according there age following using set::combine in cakephp.

array(    [20] => array(                  [0] => array(                              'name' => "bob",                              'age'  => 20,                              'marks'=> 50                              )                  [1] => array(                              'name' => "ryan",                              'age'  => 20,                              'marks'=> 57                              )                 )    [23] => array(                  [0] => array(                              'name' => "allen",                              'age'  => 23,                              'marks'=> 70                              )                  [1] => array(                              'name' => "duke",                              'age'  => 23,                              'marks'=> 67                              )                 )    [24] => array(                  [0] => array(                              'name' => "matt",                              'age'  => 24,                              'marks'=> 85                              )                 )   ) 

i'm able 1 content particular age.

if understood question correctly, can obtain want using (tested cakephp 3):

hash::combine($array, '{n}.user', '{n}', '{n}.age') ; 

you can use array_map , array_values want:

array_map('array_values', hash::combine($array, '{n}.name', '{n}', '{n}.age')) 

do not forget add following use statement: use \cake\utility\hash ;

edit: looks using cakephp 2, above should work, need replace hash set:

array_map('array_values', set::combine($array, '{n}.name', '{n}', '{n}.age')) 

example:

$array = array(     0 => array(         'name' => "bob",         'age'  => 20,         'marks'=> 50     ),     1 => array(         'name' => "ryan",         'age'  => 20,         'marks'=> 57     ),     2 => array(         'name' => "allen",         'age'  => 23,         'marks'=> 70     ),     3 => array(         'name' => "duke",         'age'  => 23,         'marks'=> 67     ),     4 => array(         'name' => "matt",         'age'  => 24,         'marks'=> 85     ) ) ; debug($array); debug(\cake\utility\hash::combine($array, '{n}.user', '{n}', '{n}.age')); debug(array_map('array_values', \cake\utility\hash::combine($array, '{n}.name', '{n}', '{n}.age'))); 

output:
