JSONc (JSON compressed)

A compressed way to parse objects/asociative arrays

How does it work?

When you have an associative array, it breaks into an array of keys, and array of values.

Small example:

{"data": [{"my_key": "my_val1"},{"my_key": "my_val2"},{"my_key": "my_val3"},{"my_key": "my_val4"},{"my_key": "my_val5"},{"my_key": "my_val6"},{"my_key": "my_val7"},{"my_key": "my_val8"},{"my_key": "my_val9"}]} = 209

Compressed:

{"data": {"keys": ["my_key"], "data":["my_val1","my_val2","my_val3","my_val4","my_val5","my_val6","my_val7","my_val8","my_val9"]}} = 130

Ratio: 130/209 = 62%

Big example (example/example.php):

Same ratio for 100, 1000, or 50000 rows. ~ 45% for fair data

Number of rows: 50,000

JSON Compressed size: 21.55MB

JSON size: 47.3MB

Compressed size compared to uncompressed size: 45.57%

Usage

    $.ajax({dataType: "jsonc"});

	header('Content-Type: application/x-jsonc');
    jsonc_encode($my_array, $my_keys);

Where $my_keys is an array of the keys that contain the associative arrays. In my example, just ["data"]

Dependencies

• jQuery (code contains an ajax type extension)
