Imagine a counter with an initial value of 0   For every loop  increment the counter value by 1 using  counter   0   The final counter value returned by the loop will be the number of iterations of your for loop  Find the code below     counter   0  foreach   Contents as  item         counter         item number     if there are 15  item number  in this foreach  I want get the value    15      Try that

There s a few different ways you can tackle this one     You can set a counter before the foreach   and then just iterate through which is the easiest approach     counter   0  foreach   Contents as  item           counter            item number     if there are 15  item number  in this foreach  I want get the value   15

If you just want to find out the number of elements in an array  use count  Now  to answer your question        How to calculate how many items in a foreach     i   0  foreach   Contents as  item         item number     if there are 15  item number  in this foreach  I want get the value   15      i        If you only need the index inside the loop  you could use  foreach  Contents as  index  gt  item            index goes from 0 up to count  Contents  - 1         item iterates over the elements
