#Config

A simple Config object that loads a JSON file and lets you access values without having to check if they're set first. Then automatically saves back to the JSON file when your script finishes. It inherits all the getting/setting abilities from Nest.

##Example

$Config = new \Hambrook\Config\Config("settings.json");

JSON File (settings.json)

{
	"foo": "bar",
	"one": {
		"two": "three"
	}
};

####Use a string as the path parameter

$value = $Config->get("foo");
// "bar"

####We're going two levels in this time, so use an array for the path

$value = $Config->get(["one", "two"]);
// "three"

####What if we try to get something that isn't there? Does it error?

$value = $Config->get(["nope", "two"]);
// returns `null`, not an error

####Or we can specify our own default in case of error

$value = $Config->get(["nope", "two"], "safe");
// returns "safe", not an error

##Saving By default, Config will auto-save at the end of the script. If you instanciate Config with false as the second parameter, then it will no longer auto-save.

You can save at any time by using the save() function.

// Save the JSON encoded data to the file and returns `$this`
$Config->save();

##Shortcuts You can use __ (by default) as a separator instead of using an array, then you can do things like...

// Get a nested value
$value = Config->one__two
// "three"

// Get a nested value that isn't there
$value = Config->one__bad
// null

// Get a nested value, with a default if the value isn't there
$value = Config->one__bad("default")
// "default"

// Get a nested value, with a default if the value isn't there
$value = Config->one__two = "newthree"
// sets the value to "newthree" then returns `$this`

##Who is it for? Config was built for small CLI scripts and tools. But it can be used anywhere.

##Feedback Tell me if you loved it. Tell me if you hated it. Tell me if you used it and thought "meh". I'm keen to hear your feedback.

##Roadmap

• Add any other standard documentation that should be included
• Add proper unit tests
• If you have an idea, let me know.
