JsObject

Object Methods

Here most of the useful Object methods are covered.

You can declare a JsObject simply-

$object = new JsObject([
    'name' => 'John Doe',
    'email' => '[email protected]',
    'age' => 24,
    'gender' => 'male'
]);

or 

$object = new JsObject([1, 2, 3, 4]); // In this case the object will be [0 => 1, 1 => 2, 2 => 3, 3 => 4]

Note that the $object here is not a native PHP object or stdClass, rather it's an instance of JsObject. But don't worry, you can perform operations like-

$name = $object->name;
$email = $object->email;

print_r($name); // "John Doe"
print_r($email); // "[email protected]"

You can change or set new value in the $object like native.

// Changing existing value
$object->name = 'Alice Bob';
print_r($object->name); // "Alice Bob"

// Set a new value.
$object->phone = '12345678';
print_r($object->phone); // "12345678" 

Even you can iterate through the $array like native array.

foreach ($object as $key => $value)
{
    echo $key . " => " . $value . "\n";
}

// Output:
// "name" => "Alice Bob"
// "email" => "[email protected]"
// "age" => 24
// "gender" => "male"
// "phone" => "12345678"

But note that, if you want to get the raw PHP object i.e. an stdClass object then use the ->get() method.

$elements = $object->get();
print_r($elements);
// Expected output:

//stdClass Object (
//  [name] => Alice Bob
//  [email] => [email protected]
//  [age] => 24
//  [gender] => male
//  [phone] => 12345678
//)

Now you can perform any native PHP methods on the $elements object.

# JsObject::assign()

The JsObject::assign() static method copies all the properties from one or more sources to a target object and return the object. This method does not change any original object.

Example

$target = new JsObject(['name' => 'Jon Doe','age' => 24]);
$source = new JsObject([ 'name' => 'Alice', 'age' => 28, 'phone' => 332232]);
$result = JsObject::assign($target, $source);

print_r($result->get());
// output: ['name' => 'Alice', 'age' => 28, 'phone' => 332232]

Syntax

JsObject::assign($target, ...$sources);

Parameters

• $target The target object where to assign the source properties.
• $sources The source object(s) — objects containing the properties you want to apply.

Return Value

JsObject, with the updated $target object.

---

# JsObject::entries()

The entries() method returns an array or more specifically JsArray instance of a given Object's string-keyed property-value [key, value] pairs.

Example

$object = new JsObject([
	'name' => 'Jon Doe',
	'age' => 32
]);

JsObject::entries($object)->forEach(function($item) {
	list ($key, $value) = $item;
	echo $key . ' => ' . $value . "\n";
});

// Output: name => Jon Doe
//         age => 32

Syntax

JsObject::entries($object);

Parameters

• $object The object to find the entries. The object would be a sequential or an associative array, a stdClass or a JsObject instance.

Return Value

JsArray — an instance of JsArray which containing the [key, value] pairs.

---

# JsObject::fromEntries()

The JsObject::fromEntries() method transforms a list of key-value pairs into an JsObject instance.

Example

$entries = [['foo', 'bar'], ['baz', 'alice']];
$object = JsObject::fromEntries($entries);
print_r($object->get());

/**
Output:
stdClass Object (
   [foo] => bar
   [baz] => alice
)
*/

Syntax

JsObject::fromEntries($entries);

Parameters

• $entries The key-value paired entries array. This could be a plain array or an instance of JsArray.

Return Value

JsObject - An object generated from the entries.

---

# JsObject::keys()

The JsObject::keys() method returns a JsArray instance of a given object's own property names.

Example

$object = new JsObject([
	'name' => 'Jon Doe',
	'age' => 32,
	'phone' => 33432
]);

$keys = JsObject::keys($object);

print_r($keys); // Output: ['name', 'age', 'phone']

Syntax

JsObject::keys($object);

Parameters

• $object The object which keys we need to extract. The $object would be an associative or sequential array, a stdClass or a JsObject instance.

Return Value

JsArray instance with the keys of the object.

---

# JsObject::values()

The JsObject::values() method returns a JsArray instance of a given object's values.

Example

$object = new JsObject([
	'name' => 'Jon Doe',
	'age' => 32,
	'phone' => 33432
]);

$keys = JsObject::values($object);

print_r($keys); // Output: ['Jon Doe', 32, 33432]

Syntax

JsObject::values($object);

Parameters

• $object The object which values we need to extract. The $object would be an associative or sequential array, a stdClass or a JsObject instance.

Return Value

JsArray instance with the values of the object.
