PHP multidimensional array to JSON

Question

So im trying to figure out the best way to get MySql table data into either a multidimensional PHP array or convert that multidimensional array into a json string.

JS arrays have an implicit array keying, starting at index 0. What you've got is a perfectly valid JS array, the equivalent of having written:

var x = []; // create new empty array
x[0] = {"key1": .... }; // first object
x[1] = {"key2": ....} // second object

Note that the contents of your {} sub-objects is NOT valid.

You should never EVER built a JSON string by hand. It's too unreliable and easy to mess up. It's just easier to use a native data structure (php arrays/objects), then json_encode() them. Ditto on the other end of the process - don't decode the string manually. Convert to a native data structure (e.g. json_decode(), JSON.parse()) and then deal with the native structure directly.

essentially, JSON is a transmission format, not a manipulation format.
