php - Add String to Array, Stay as Array -

i have 2 arrays:

$delete = array("delete" => "delete");  $folders = array("0" => "folder1","1" => "folder2");  $options = array_merge($delete, $folders); 

how add "move " $folders , have $options stay array?

in drop down menu appear as:

delete  move folder1  move folder2 

if want add "move to" string every element of $folder array, try this:

$folders = array("0" => "folder1","1" => "folder2"); foreach($folders $key => $value) {     $folders[$key] = 'move '.$value; } $options = array_merge($delete, $folders); 

or (based on suggestion of @zamnuts)

$folders = array("0" => "folder1","1" => "folder2");  function moveto($n) {        return 'move '.$n;  } $folders = array_map("moveto", $folders); $options = array_merge($delete, $folders);
