Merubah bentuk array

Assalamualaikum,
 
Maaf temen-temen semua mungkin disini ada yang paham bagaiman cara merubah bentuk array...
 
Saya ada data seperti ini :
 
$data_contoh = array(
								array(
									'tahun' => 2018,
						            'bulan' => 1,
						            'nyeri' => 35,
						            'jatuh' => 19,
						            'dekubitus' => 9,
						            'nilai_budaya' => 20,
						            'sosial' => 22,
						            'spiritual' => 30,
						            'psikologi' => 25,
						            'disscharge_planning' => 17,
						            'riwayat_alergi' => 27,
						            'edukasi_terintegrasi' => 8,
						            'skrining_gizi' => 36,
						            'kajian_status' => 27),
								array(
									'tahun' => 2018,
						            'bulan' => 2,
						            'nyeri' => 30,
						            'jatuh' => 19,
						            'dekubitus' => 19,
						            'nilai_budaya' => 26,
						            'sosial' => 22,
						            'spiritual' => 30,
						            'psikologi' => 20,
						            'disscharge_planning' => 17,
						            'riwayat_alergi' => 27,
						            'edukasi_terintegrasi' => 8,
						            'skrining_gizi' => 33,
						            'kajian_status' => 23),
								array(
									'tahun' => 2018,
						            'bulan' => 3,
						            'nyeri' => 35,
						            'jatuh' => 1,
						            'dekubitus' => 19,
						            'nilai_budaya' => 20,
						            'sosial' => 22,
						            'spiritual' => 30,
						            'psikologi' => 15,
						            'disscharge_planning' => 17,
						            'riwayat_alergi' => 27,
						            'edukasi_terintegrasi' => 18,
						            'skrining_gizi' => 23,
						            'kajian_status' => 33),
							);
 
Dan saya ingin menjadikan bentuk array diatas menjadi seperti ini :
 
$data_hasil_akhir = array( 'nyeri' =>
							array(
								'2018_1' => 35,
								'2018_2' => 30,
								'2018_3' => 35
							),
								'jatuh' =>
							array(
								'2018_1' => 19,
								'2018_2' => 19,
								'2018_3' => 1
							),
								'dekubitus' =>
							array(
								'2018_1' => 19,
								'2018_2' => 19,
								'2018_3' => 9
							),
								'nilai_budaya' =>
							array(
								'2018_1' => 20,
								'2018_2' => 26,
								'2018_3' => 20
							),
								'sosial' =>
							array(
								'2018_1' => 22,
								'2018_2' => 22,
								'2018_3' => 22
							),
								'spiritual' =>
							array(
								'2018_1' => 30,
								'2018_2' => 30,
								'2018_3' => 30
							),
								'psikologi' =>
							array(
								'2018_1' => 25,
								'2018_2' => 20,
								'2018_3' => 15
							),
								'disscharge_planning' =>
							array(
								'2018_1' => 17,
								'2018_2' => 17,
								'2018_3' => 17
							),
								'riwayat_alergi' =>
							array(
								'2018_1' => 27,
								'2018_2' => 27,
								'2018_3' => 27
							),
								'edukasi_terintegrasi' =>
							array(
								'2018_1' => 18,
								'2018_2' => 8,
								'2018_3' => 8
							),
								'skrining_gizi' =>
							array(
								'2018_1' => 36,
								'2018_2' => 33,
								'2018_3' => 23
							),
								'kajian_status' =>
							array(
								'2018_1' => 27,
								'2018_2' => 23,
								'2018_3' => 33
							)
);
