Arranging array in php -


my problem can't arrange array in structure want. array1 , array2 generated dynamically. can see in array 2 has subjectid same in array1, means, element under subject cpe 305. elements in array 2 has id of 5 under the subject of cpe 305. same logic cpe 304.

array1:

array ( [0] => array     (         [subjectid] => 5         [subjectcode] => cpe 305     )  [1] => array     (         [subjectid] => 4         [subjectcode] => cpe 304     )  )

array2:

array ( [0] => array     (         [subjectid] => 5         [soid] => 1         [socode] =>         [sodesc] => ability apply knowledge of mathematics , science solve engineering problems     )  [1] => array     (         [subjectid] => 5         [soid] => 3         [socode] => c         [sodesc] => ability design system, component, or process meet desired needs within realistic constraints such economic, environmental, social, political, ethical, health , safety, manufacturability, , sustainability, in accordance standards     )  [2] => array     (         [subjectid] => 5         [soid] => 4         [socode] => d         [sodesc] => ability function on multidisciplinary teams     )  [3] => array     (         [subjectid] => 5         [soid] => 5         [socode] => e         [sodesc] => ability identify, formulate, , solve engineering problems     )  [4] => array     (         [subjectid] => 5         [soid] => 9         [socode] =>         [sodesc] => recognition of need for, , ability engage in life-long learning     )  [5] => array     (         [subjectid] => 4         [soid] => 10         [socode] => j         [sodesc] => knowledge of contemporary issues     )

)

output (my desired structure)

array(  [subjectid] => 5  [subjectcode] => cpe 305  [sodetails] => array(                 [0]=>array ([soid]=>1                             [socode]=>a)                 [1]=>array([soid]=>3                            [socode]=>c .....until last                  )  [subjectid] => 4  [subjectcode] => cpe 305  [sodetails] => array(                 [0]=>array ([soid]=>10                             [socode]=>j)                                       .......until last                  )

what i've tried

this code im testing. include few data here in test code. 

      $so = array();       $exist = array();           foreach ($this->subject $key => $value) {           foreach ($this->sodetails $key2 => $value2) {             if($value['subjectid'] === $value2['subjectid']){                $exist = array(                   "subjectid" => $value['subjectid'],                   "details" =>array(                     "soid" => $value2['soid']                   )               );               array_push($so, $exist);             }           }         }

first of output array incorrect. array cannot have more 1 same indexes "subjectid", "subjectcode". need have different index. wise use subjectid index outer array.

first prepare outer array array1.

foreach($this->subject $key => $val){     $myarray[$val['subjectid']]['subjectid'] => $val['subjectid'];     $myarray[$val['subjectid']]['subjectcode'] => $val['subjectcode']; }

now iterate sodetails array.

foreach($this->sodetails $key => $val){     $temp['soid'] = $val['soid'];     $temp['socode'] = $val['socode'];     array_push($myarray[$val['subjectid']]['sodetails'], $temp); }

there can other ways too. style , believe solve problem.
