Change array key without changing order

Question

You can \"change\" the key of an array element simply by setting the new key and removing the old:

$array[$newKey] = $array[$oldKey];
unset($array[$oldKey]);         


        

Answer 1

Something like this may also work:

$langs = array("EN" => "English", 
        "ZH" => "Chinese", 
        "DA" => "Danish",
        "NL" => "Dutch", 
        "FI" => "Finnish", 
        "FR" => "French",
        "DE" => "German");
$json = str_replace('"EN":', '"en":', json_encode($langs));
print_r(json_decode($json, true));

OUTPUT:

Array
(
    [en] => English
    [ZH] => Chinese
    [DA] => Danish
    [NL] => Dutch
    [FI] => Finnish
    [FR] => French
    [DE] => German
)
