How can I convert a PHP array in a format like this

    [1] => 1234567
    [2] => 12345678
    [3] => 12345678
    [4] => 12345678
    [5] => AP1W3242
    [6] => AP7X1234
    [7] => AS1234
    [8] => MH9Z2324
    [9] => MX1234
    [10] => TN1A3242
    [11] => ZZ1234
)

to a Javascript array in the format below?

var cities = [
    "Aberdeen",
    "Ada",
    "Adamsville",
    "Addyston",
    "Adelphi",
    "Adena",

];
