$bit_depth=[8,16]; 

//expected output
$data = [ 
 'satu' => [  
   'nama_file' = 'wajah1.png', 
   'id' = 'orang1', 
   'bit-depth' = 8, 
 ], 
 'dua' => [  
   'nama_file' = 'wajah2.png', 
   'id' = 'orang2', 
   'bit-depth' = 16, 
 ] 
]; 
?>

Ini asumsi length kedua arrah nya sama

for (i = 0; i < data.length; i++ ) {
data['bit-depth'] = bit-depth[i]
}
