php - Covert multi dimensions array into key values -

sorry wrong described got that.

array (     [0] => hello[30815][183]     [1] => hello[30815][291][28280]     [2] => hello[30815][291][28280][custom_math]     [3] => hello[30815][472][28273][comment] ) 

after add loop

for($i=0; $i<=count($cfn);$i++)         {             echo $cfn[$i] ;             echo '<br>';             echo $cfv[$i];             echo '<br>';         } 

i got type of array

hello[30815][183] => 28275 hello[30815][291][28280] =>  hello[30815][291][28280][custom_math] => noce hello[30815][472][28273][comment] =>  

i want convert

[hello] => array         (             [183] => 28275             [291] => array                 (                     [28280] =>                   )             [291] => array                 (                     [28280] =>  array                         (                             [custom_math] => noce                         )                 )              [472] => array                 (                     [28273] => array                         (                             [comment] =>                          )                  )          ) 

how in php. array length not fixed.30815 id common in all. how resolve issue.

$data //array processing data $productvalue // array values  $final = array(); $i=0; foreach ($data $value) {     $firststrips = explode("[", $value);     $process = array();     foreach($firststrips $key =>  $firststrip){         if($key==0 || $key==1 ){             continue;         }         $firststrip = str_replace("]", "", $firststrip);         $process[] =(string)$firststrip;     }     $testarray = convert($process, $productvalue[$i]);     $final= array_merge_recursive($testarray,$final);     $i++; }  function convert($final='', $datavalue) {     $out = array();     $cur = &$out;     foreach ($final $value) {         $cur[$value." "] = array();         (string)$cur = &$cur[$value." "];         $i++;     }     $cur = $datavalue;     return $out; }  print_r($final);
