Merge 2 arrays in CakePHP

I have two arrays array1 and array2. I want to merge these two arrays into one and show the values of merged array in a dropdown. I want the values in a way that the value of first array - value of 2nd array.

e.g: 

$employeePlaces1 = array(1, 2, 4,9);
$employeePlaces2 = array(3, 5, 6,7);

I want in dropdown the value as $employeePlaces1[0]-$employeePlaces2[1], $employeePlaces1[0]-$employeePlaces2[1].

    1-3,
    2-5,
    4-6, 
    9-7.

How can I do this ?

$employee1 = array(1, 2, 4, 9);
$employee2 = array(3, 5, 6, 7);

function doMerge($n, $m) {
    return $n.'-'.$m;
}


$c = array_map("doMerge", $employee1, $employee2);

print_r($c);

Or in PHP 5.3 syntax with lambda style functions:

$c = array_map(function($n, $m) {return $n.'-'.$m;}, $employee1, $employee2);

Here is how you could manually loop through them and match the values together.

$list = array();
for($i=0; $i<=count($employeePlaces1); $i++) {
    $list[] = $employeePlaces1[$i].'-'.$employeePlaces2[$i];
}

Haven't tested, but should be the gist of what you need.

Why not just loop over the arrays, i.e. do it longhand. Then you can get on with something else!

Edit in response to comment 1:

CakePHP is expecting:

<?php echo $this->Form->input('field', array('options' => array(
    'Value 1'=>'Label 1',
    'Value 2'=>'Label 2',
    'Value 3'=>'Label 3'
 ))); ?>

so something like (pseudocode):

resultsArray = array();
loop
    resultsArray[i] = inputArray_1[i]-inputArray_2[i];
endloop

in PHP (assumes size of array1 <= size of array2):

for($i=0;$i<count($inputArray_1);$i++)
{
    $resultsArr[$i] = $inputArray_1[$i]-$inputArray_2[$i];
}

You can use the array_diff function

http://www.php.net/manual/en/function.array-diff.php

Answer for the edited question

//assuming both the arrays have the same length
echo "<select>";
for($i=0;$i<count($employeePlaces1);$i++)
{
    echo "<option>".$employeePlaces1[i]." - ".$employeePlaces2[i]."</option>";
}
echo "</select>";

How about using array_combine?
