Hi Friends,
I am having a 2-Diamentional array like
[AED] => Array
(
[Name] => United Arab Emirates Dirham
[Amount] => 3.73723
)

[ARS] => Array
(
[Name] => Argentine Peso
[Amount] => 4.60188
)

I am working on a silverstripe form with a dropdown box.Now i need to add the values of options to the dropdownbox as the keys of array and text as the concatination of key and value pair as example below.
i.e <option value="AED">AED(Argentine Peso)</option>
<option value="ARS">ARS(Argentine Peso)</option>

All you need to do is iterate through your current array and build a new one.

$input = // your current array
$output = array(); // new array

foreach($input as $k => $v) {
$output[$k] = $k . ' ('. $v['Name'] .')';
}

Then use $output as your source in the dropdown field.
