PHP: Array to string? Array of Key/value pairs into simple value list? [duplicate]

Question

I am sure this is something simple, but I can't find it anywhere:

How can I change an array like this:

{ [0]=> string(3) "674" [1]=> string(3) "675" [2]=> string(3) "676" [3]=> string(3) "677" } 

into a simple one like this:

(674,675,676,677)

For use in another SQL (IN) query?

I have tried imploding and it fails.

$myarray_value = implode( ',', $myarray );

What you are looking at is in JSON format, so just do this:

$string = '{ [0]=> string(3) "674" [1]=> string(3) "675" [2]=> string(3) "676" [3]=> string(3) "677" }';
$array = json_decode($string);
print_r($array);
