JCOF (PHP) JSON Compact Object Format
=====================================

[](#jcof-php-json-compact-object-format)

A more efficient way to represent JSON-style objects.

About
-----

[](#about)

JCOF tries to be a drop-in replacement for JSON, with most of the same semantics, but with a much more compact representation of objects. The main way it does this is to introduce a string table at the beginning of the object, and then replace all strings with indexes into that string table. It also employs a few extra tricks to make objects as small as possible, without losing the most important benefits of JSON. Most importantly, it remains a text-based, schemaless format.

Example JSON object (299 byte):\*\*\*\*

```
{
	"people": [
		{"first-name": "Bob", "age": 32, "occupation": "Plumber", "full-time": true},
		{"first-name": "Alice", "age": 28, "occupation": "Programmer", "full-time": true},
		{"first-name": "Bernard", "age": 36, "occupation": null, "full-time": null},
		{"first-name": "El", "age": 57, "occupation": "Programmer", "full-time": false}
	]
}
```

Coverted JCOF object (134 byte) 55% lower :

```
Programmer;"age""first-name""full-time""occupation";
{"people"[(0,iw"Bob"b"Plumber")(0,is"Alice"b,s0)(0,iA"Bernard"n,n)(0,iV"El"B,s0)]}

```
