来自数组的php for循环在3个循环后停止

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++)
