I'm not sure what internal pointer they are talking about?
Is this pointer the symbols, brackets, etc.. that I see typed onto the page?
Here is what I'm talking about,
<?php
$fruits = array('apple', 'banana', 'cranberry');
echo end($fruits); // cranberry
?>
Yes, I know what an Array is.
That is not the problem. I also know what first and last means too. I've taken all the classes on calculus, Computers Concepts and Applications.
So, yes, Cranberry is the last item. So, yes, as you can see, I understand that.
apple is the first one, banana is the 2nd item.
I set the DVD/VCR to start recording and stop at a certain time all the time.
So, I know how to calculate things. Since I have to do that in order to have it stop about 7 minutes sometimes past when the show is due to end, in case of other things with the clock that maybe off a bit.
Also, sorry if I sound like I'm confused. I'm sick anyways all the time and just had Hepatitis A, and still dealing with affects from that which affects my memory and stress makes things worse too. I'm trying to get all the basic information about things in life all written down, so that in case I go into problems again where I don't even know how to spell my own name, I can look back at information for things.
So, yes, I've already learned all these topics years ago is what I'm trying to say, and got A's in the classes too. Which is why going out to take a class or something, which I can't physically do any of that due to my health being worse.
Thanks,
Amy
