Change all array values

All values of my arrays in a multidimensional array consists of one variable + string.

How can I change all values from array[2] and array[3] in my example? I want to change the variable called $var with $var2 and put another variable called $between between $var2 and the string.

Example

$var = "start-";
$array = array
  (
  array("{$var}end1a","{$var}end2a","{$var}end3a"),
  array("{$var}end1b","{$var}end2b","{$var}end3b"),
  array("{$var}end1c","{$var}end2c","{$var}end3c")
  );

    $var2 = "new-start-";
    $between = "between-";

result 

$array[2]=array("{$var2}{$between}end1","{$var2}{$between}end2","{$var2} {$between}end3");
$array[3]=array("{$var2}{$between}end1","{$var2}{$between}end2","{$var2} {$between}end3");

UPDATE: First I had only an one-dimensional array and the answer from maxhud was perfect for this case.

$start = "start-";

$array = array(
    array($start."enda1", $start."enda2", $start."enda3"),
    array($start."endb1", $start."endb2", $start."endb3"),
    array($start."endc1", $start."endc2", $start."endc3")
);

$newStart = "new-start-";
$between = "between-";

$keys = array(2, 5);

foreach ($keys as $key) {
    foreach ($array[$key] as $key2 => $value) {
        $array[$key][$key2] = str_replace($start, $newStart.$between, $value);
    }
}
