Sure you are. You provided the following URL:
mypage.php?var=2&var=4&var=5 In this case, you've named all three
variables var. What would you expect the following code to output:

$x = 2;
$x = 4;
$x = 5;
echo $x;

This will echo 5 because you've given a new value to $x on the second
line, and overwrote it again on the third line. The same thing happens
with your URL. The last value of var overwrites the first and second
value. As such, you get var = 5 on mypage.php.

You can do one of two things here: either give each variable a
different name, like mypage.php?var1=2&var2=4&var3=5 in which case
you'd refer to them as $_GET['var1'], $_GET['var2'], etc.

Alternatively you can make var an array in the URL and access it like
an array on mypage.php. For instance, your URL might look like this:
mypage.php?var[0]=2&var[1]=4&var[2]=5. On mypage.php, you can get to
those like this: $_GET['var'][0], $_GET['var'][1], etc.
