Walking through an array

[TrulyUnusualdotcom]

I'm reading PHP & MySQL for Dummies 2nd edition...ya ya I know..lame.
Anyway I got to the part about walking through an array and I just can't
seem to figure out what this would be used for. What is the point of this?
When would you use this? It says in great detail how to do it but it's
missing the the why and where.

Any help would be greatly appreciated.
Jon

Forgive me if I'm wrong but

.... this sounds as if you're learning programming and doing it
"backwards. "

IMHO the best way to learn is to start writting your application then
learn the tools as you need them. "Walking" through an array will
eventually show up - I pretty much guarantee it.

Re: Walking through an array

You might be right on the money there but I need to start somewhere... lol
I wanted to get through this book and then start so my trial and error could
be a little shorter that it usually is learning new things. My biggest
obsticle is a starting point. I was hoping this book would give me at least
that.

Try downloading the PHP reference manual. It has examples of things like
array_walk

I've never used array_walk Maybe I just never thought of using it and
coded it another way. But I wonder if the user was getting confused
with looping through an array which is used frequently?

But what tony says is correct, learn the basics, variables, if/else,
loops and few useful functions and the GET CODING. Your code will be an
inefficient mess at first but you can improve on that later. If you try
to learn it all before you start your head will explode.
