|So I apologize for that.   

|I've shown you this in my earlier tutorials and we'll have the numbers 1 2 3 4 5 6 7 8 9 and 10

|Ok. So, a '''foreach''' is like this.  

|So, we have '''foreach''' and then we have our '''condition''' here .  Well, I don't know what to call it.

|And then we say as and then we say value.  So we can give this any name.   

|And then inside the curly brackets,  the fundamental '''command''' would be '''echo''' '''value'''.

|And we'll concatenate a line break in the end and let's have a look at this.

|So, that echoed through our loop. It's a really easy way to '''echo''' through our loop. You can use other loops to echo through an '''array'''. You have to write it manually, however and this is probably the easiest way to do it.

|So as long as you remember this, you can '''echo''' through your array, perform '''operations''' on each part of your array and then may be store it in a new array.

|Now, what I'll do is - I'm going to do the 2 times table.

|So, I need the number in the array here times 2 is and then outside of this is going to be the new value.  So we're going to times each element of the array - each number in the array by 2.

|Sorry, we're going to say '''value''' because we have stored each '''foreach''' element in this variable name '''value'''.

|So, '''value''' is each of these in turn, through the loop.

|Therefore, value times 2 is and then after this we'll put some brackets.  Inside we'll type "value times 2".

|Remember this is a mathematical operator - an arithmetical operator that I showed you earlier.

|Now, to make this interesting, what I'll do is to make this as a multiple

|and the multiple up here

|is going to equal 2.  So you can guess by now that I've basically replaced that.

|Oh! We forgot the break.

|2 times 2 is 4 all the way up to 10 times 2 is 20.

|We can change this, let's say we want the 10 times table.

|'''Refresh''', 1 times 2 is... Oh! nah, we forgot to change this 2 into multiple.

|Now it will echo our number.  

|So, 1 times 10 is 10, 2 times 2 is, 2 times 10 is 20, 10 times 10 is a hundred.

|So, as long as we change the value of the multiple - let's say the 12 times table.  

|So, from this '''FOREACH''' loop and array I've created a really basic, multiple program with which you can see the times table for any set of numbers you like.
