Hi,

I have this for loop:

for ($i = $postNumber; $i > 0; $i--){
  print "$i<br>";
}

and what it does it count backwards to 0 (to 1, you don't see a 0) from whatever $postNumber is. $postNumber is always a number.

So let's say $postNumber is 5. The loop would say:
5
4
3
2
1
with line breaks separating each number.

My question is, in the above scenario, how do I turn the first number echoed (the 5) into a variable? It's not an array, or a string... I don't know what it is!

Thanks,

Not exactly sure if this is what you want:

PHP Code:

for ($i = $postNumber; $i > 0; $i--)
{
  print "$i<br>";
  if ($i == $postNumber)
     {
       $php_variable = $i;
     }
} 


Now $php_variable equals 5

What do you mean by turn it into a variable?

Thanks rfresh,

And NullPointer, what I'm doing with this is very complicated, but I'll do my best D: .

Ok so I have a script that adds posts to a database. The posts go in most recent order. So let's say you make a 'post'. It will be there. You make another post, it will not be on top of the first one. Now the file looks something like this:

Second Post|First Post

Second post is before First post.

Now I want to number these posts. Second post will be #1, and First post will be #2 (Yes, that way. Don't ask why, or I'll have to explain that, too D: ). If you add a third post...

First post will be #3, second post will be #2, and third post will be #1.

I need to keep track of these, somehow.

This is what I want:
$postNumber: First post|$postNumber: Second post|$postNumber: Third post.........

You know. But $postNumber would have to be fixed, and I'm writing this to a file, so opening and closing it, then reopening and closing it many times just to add one post hogs bandwidth. I don't want to put an fwrite in a loop

How can I possibly do this? With some uber mega ultra super coding?

Thanks

I think I see what you are going for.

Can't you just count the number of posts and then display then just count down as you display each post:

PHP Code:

$posts; //array of posts
$postCount = count($posts);

foreach($posts as $p)
{
     echo $postCount . ': ' . $p . '<br />';
     $postCount--;
} 


Ah, that should do it! I can't test it right now, I'm not on Linux (where my file is), but it sure looks good! Thanks, man!
