arrays - PHP Multidimensional array_reverse values -

i need reverse order of values in array:

// current array looks // echo json_encode($array);      { "t" : [ 1, 2, 3, 4, 5, 6 ],       "o" : [ 1.1, 2.2, 3.3, 4.4, 5.5, 6.6 ],       "h" : [ 1.2, 2.2, 3.2, 4.2, 5.2, 6.2 ]      } 

i need invert values keeping keys should this:

// echo json_encode($newarray);      { "t" : [6, 5, 4, 3, 2, 1 ],       "o" : [ 6.6, 5.5, 4.4, 3.3, 2.2, 1.1],       "h" : [ 6.2, 5.2, 4.2, 3.2, 2.2, 1.2 ]      } 

what have tried without success:

<?php $newarray= array_reverse($array, true); echo json_encode($newarray); /* above code output (note values keep order):   {     "h":[1.2, 2.2, 3.2, 4.2, 5.2, 6.2]     "o":[1.1, 2.2, 3.3, 4.4, 5.5, 6.6]     "t":[1,2,3,4,5,6]    }         */  ?> 

after reading similar question here, tried following without success:

<?php $k = array_keys($array);  $v = array_values($array);  $rv = array_reverse($v);  $newarray = array_combine($k, $rv);  echo json_encode($b);  /* above code change association of values = keys, output:   { "h": [1.1, 2.2, 3.3, 4.4, 5.5, 6.6],     "o": [1,2,3,4,5,6],     "t": [1.2, 2.2, 3.2, 4.2, 5.2, 6.2]   }   ?> 

thank time.

haven't tested it, should it:

$newarray = array(); foreach($array $key => $val) {     $newarray[$key] = array_reverse($val); }
