For an array like below; what would be the best way to get the array values and store them in a variable as a string?

Array ( [0] => 33160 [1] => 33280 [2] => 33180 [3] => 33163 [4] => 33181 [5] => 33164 [6] => 33162 [7] => 33179 [8] => 33154 [9] => 33008 [10] => 33009 [11] => 33161 [12] => 33261 [13] => 33269 [14] => 33169 [15] => 33022 [16] => 33141 [17] => 33168 [18] => 33020 [19] => 33023 [20] => 33019 [21] => 33153 [22] => 33238 [23] => 33138 [24] => 33167 [25] => 33082 )

Why does this need to be a string? How would you like this string to be formatted? What are you doing with it? More details would be nice. – Rocket Hazmat Nov 23 '10 at 20:34
just comma separated zipcodes like so 33160,33280,33180 etc... – user74283 Nov 23 '10 at 20:45

I would turn it into CSV form, like so:

$string_version = implode(',', $original_array)

You can turn it back by doing:

$destination_array = explode(',', $string_version)

CSV is the format user74283's specifies in his comment on his question. – Isaac Sutherland Nov 23 '10 at 22:03

I would turn it into a json object:

 $stringRepresentation= json_encode($arr);

serialize() and unserialize() convert between php objects and a string representation.

Using implode(), you can turn the array into a string.

$str = implode(',', $array); // 33160,33280,33180,...
