php for loop from array stops after 3 loops

Question

I have an array that looks like this.

Array (
    [0] => Array (
        [0] => MDT 2920 P
        [1] => MDT 1210 P
        [2] => MDT 939 P
        [3] => MDT 1760 P
        [4] => PDT 23800 P
    )
    [1] => Array (
        [0] => MDT
        [1] => MDT
        [2] => MDT
        [3] => MDT
        [4] => PDT
    )
    [2] => Array (
        [0] => 2920
        [1] => 1210
        [2] => 939
        [3] => 1760
        [4] => 23800
    )
)

I want to loop through array in the first key of [2] and echo all the values.

for ($i = 0; $i < count($nt); $i++)
{
    echo $nt[2][$i];
    echo "<br />";
}

this works, but stops after three loops and the output looks like this:

2920
1210
939

I am expecting -- hoping for this:

2920
1210
939
1760
23800

I don't understand why it is stopping. thanks.

Your problem lies here:

for($i = 0; $i < count($nt); $i++) 

You are counting the elements of $nt (which are 3), but you want to access the elements of $nt[2] (which are 5). Thus, you need to change the above line to:

for($i = 0; $i < count($nt[2]); $i++)
