Knot

Knot is a very powerful tool for array. Knot help for using arrays like objects! And Knot have very rich function library.

Simple Example;

$obj = ar(1,2,3);

$obj->merge(array(3,3,4,5,6,7))->unique();

$obj->child = array("a", "b", "c");

$array = $obj->toArray();

In this example, first Knot created and Knot's data have array(1,2,3) for now. Then $obj's data is merged with array(3,3,4,5,6,7). Then array_unique function called and $obj's data changed. The next line, created child key in data and equalized to array("a", "b", "c"). In the last line, $obj's data is converted to Array.

Knot is prepared with PSR-0 and PSR-1 standards.

Install

Knot is available for Composer.

composer require knot/knot

Or download from Github.

Use like Array

Knot object can be used like Arrays. Because Knot have ArrayAccess interface.

Example:

$obj = ar();

$obj["new"]["way"] = "new way value";

$obj[][][][] = 1;

Knot's data can be changed with this way.

Other Using Ways

Also __get method can be access to Knot's data. But if target is an Array, then get return Knot Child. So functions can be used with recursive.

Also __set functions can be changed to Knot's data.

Example:

$obj = ar();

$obj->new = array(
    "way" => "new value"
);

// Returns array("way" => "new value")
$obj->new->toArray();

This is a point to take into consideration. If trying to setting nonexistent way, then Knot's data merged with stdClass objects.

Example:

$obj = ar();

$obj->new->way->foo = 1;

In this example, $obj's data's new key is changed with stdClass object.

Base Functions

Knot have many functions. Also It can be added new functions to Knot.

Knot Functions

Knot have many own functions.

get($path, [$default_value])

Knot can find target data with address. So Knot can find target with small commands.

Knot using . letter for show address.

Example Address: foo.sub.target

In this example's target is "sub" key of "foo" of Knot's data.

Let's get target with this way.

Example:

$obj = arr(array(
    "foo" => array(
        "sub" => array(
            "target" => 123
        )
    )
));

// Returns $obj["foo"]["sub"]["target"]
$target = $obj->get("foo.sub.target");

Also get can be used with default value. If get have default value and target nonexistent, then get create target and change this value to default value.

If target is nonexistent and default value doesn't given, then get throws an error.

In addition, if target is an array, then Knot will return Knot Child for recursive using.

set($path, $value)

set use same thing that get functions address usage. set change to value from target of Knot's data.

If changed value is an array, Knot return Knot Child so

In addition, if target is an array, then Knot will return Knot Child for recursive using.

del($path)

del use same thing that get functions address usage. del delete targets.
