correct

      i/p : 3 2       o/p : count-2            num2-2

my issue

      i/p : 3(just single space)      o/p : count-2             num2-

and $num2 behaving has value 0 can ...

num2 can 0 100... how acheive this

i think issue $_post['testcases'] contain trailing white space.

you should trim $_post['testcases'], explodes correctly. alter first line to:

$testcases1 = explode(" ",trim($_post['testcases']));
