php – Merge 1 Multidimensional array into a single array


I need to merge a multidimensional array to create a new array.

This is what I have

Array 
(
(0) => Array
    (
        (0) => 123  
        (1) => "Title #1"
        (2) => "Name #1"
    )
(1) => Array
    (
        (0) => 124  
        (1) => "Title #2"
        (2) => "Name #2"
    )
)

This is what I want

Array
(
   (0) => 123
   (1) => Title #1
   (2) => Name #1
   (3) => 124
   (4) => Title #2
   (5) => Name #2
)
