how to create multiple array in php(laravel5)? : I want to make multiple array by php(laravel5).  
There are two arrays as follows.

	$tags=['en' =>[]];
	$TAGS = ['test1','test2','test3',...]

I want to make this array as a return value in certain code like this:

	return [
		'tags' => [
			'en' => [
				'test1' => 'test1',
				'test2' => 'test2',
				'test3' => 'test3',
                ...
			]
		]
	]

I tried the following, but it did not work.

	return [
		'tags' => [
			'en' => [
				foreach($TAGS as $TT)
					array_push($tags['en'], $TT);
			]
		]
	]


is there any other way?  
plz your advise. thanks.
