PHP：按键对数组值进行分组

Question

I have three array like this:

array1(
   0=>'title 1',
   1=>'title 2'
)

array2(
   0=>'description 1',
   1=>'description 2'
)

array3(
   0=>'price 1',
   1=>'price 2'
)

There is a php function to grouping array values by keys like this?

array(
   0=>array(title 1, description 1, price 1),
   1=>array(title 2, description 2, price 2),
)

Answer 1

array_map(null, $array1, $array2, $array3)

See http://php.net/manual/en/function.array-map.php example #4.
