如何从数组数组中获取数组（PHP）

Question

I am receiving this when i use print_r:

Array ( 
    [0] => 15 
    [1] => 15 
    [2] => 15 
    [3] => 15 
    [4] => 15 
    [5] => 16 
    [6] => 15 
    [7] => 15 
    [8] => 15 
    [9] => 14 
    ... and so on ... 
)

and I was wondering how I can get an array of these second values (i.e.):

$newArray = array(15,15,15,15,15,16,15,15,15,14, ... );

I have tried using array_values but to no avail!

As a background, I got these results from a single column in my database and am now trying to plot them using HighRoller/HighCharts.

Thanks for the help!

You don't have an array of arrays. You have an array of values with numeric indexes. Unless I am totally misunderstanding your question ....

Array ( 
    [0] => 15 
    [1] => 15 
    [2] => 15 
    [3] => 15 
    [4] => 15 
    [5] => 16 
    [6] => 15 
    [7] => 15 
    [8] => 15 
    [9] => 14 
    ... and so on ... 
)

This means your array at index 0 has value 15 and so on.
