Loop Question

[The Hobo]

Color me stupid here, but is there a loop that doesn't require something to stop it?

I mean like:

  do {
    //blah blah, code to break in here
  } 

except that requires a while();

Right now I'm just doing this:

  do {
    //blah blah, code to break in here
  } while(1 != 2); 

Thanks in advance.

Not sure if this right but you can try this:

do {
    //blah blah, code to break in here
  } while( ; ); 

or

for( ;; ){
    //blah blah, code to break in here
} 

Take out the space in for() and while() because when I posted without the spaces, it put some other image-linking text.

or how about this. it's a never ending thread of infinite loops!

while(true) {
   // do some stuff and break it
} 

[cpradio]

why are you wanting to do this?

[The Hobo]

Because I need to be able to loop through MySQL records and I have to know as I'm working with it if it's the last record. This is a brief part of my code:

    if ($post = mysql_fetch_array($posts)) {
        do {
            //do stuff here
            
            if ($post = mysql_fetch_array($posts)) {
                //if there's another record after this one
                //do special stuff
            } else {
                //no more records after this one
                //don't do special stuff
                break;
            }
        } while (1 != 2);
    } 

That's pretty much what I"m trying to accomplish.

so why not skip the nonsense and just use:

while ($post = mysql_fetch_array($posts)) {

}

Because I need to do the fetch_array inside the loop so I can see if there is another one. If I do it this way, then It'll be skipping records:

while ($post = mysql_fetch_array($posts)) {
  //do stuff here
            
  if ($post = mysql_fetch_array($posts)) {
    //if there's another record after this one
    //do special stuff
  } else {
    //no more records after this one
    //don't do special stuff
    break;
  }
} 

It'll skip records because it's fetching twice before it prints.

I suppose I could do this:

  $num = mysql_num_rows($posts);

  for($i = 1; $i <= $num; $i++) {
    if ($post = mysql_fetch_array($posts) {
      //do stuff here
      if ($i != $num) {
        //do special stuff
      }
    } else {
      echo "No records found!";
      break;
    }
  }

I'm having troubles trying to figure out your goal, but I feel there is a better way then possiblity running an inifinite loop.

Can you give an example?

[The Hobo]

I'll try...

What I'm doing this for is that PHP NewsPro I was working on. When it prints the news, it's in a format like this:

News Item #1
------------------
News Item #2
------------------
News Item #3

The "------------------" is supposed to be a <hr>, but notice that after Item #3 there's no <hr>. So I want to place the <hr> between each news item, but I don't want to have one at the bottom of the page if there's one after it.

So I'm looping through the recordset but I have to know if the current $post is the last in the record set so I know whether or not to echo that <hr>

Does this make any sense whatsoever? I'm not sure I can explain it any better.

[cpradio]

Ahh, i see, then you want this:

for ($i=0;$i<mysql_num_rows($posts);$i++) {
  $post = mysql_fetch_array($posts)
  echo $post;
  if ($i != mysql_num_rows($posts)-1)
    echo "<hr />";
} 

[The Hobo]

Yeah, that's what I was starting to think. Thanks

[cpradio]

Yeah, anytime you start to think an infinite loop is needed, you have to kick yourself in the head b/c I doubt there is any good understandable reason you will have to use one.

BTW, did you ever receive my PM? You can ignore it now.

Well, the loop wasn't really infinite if I was breaking it, though.

I just noticed your PM. Sorry 'bout that.

Hey, you may want to look at this when it comes to finishing your forum and newspro thingy-ma-jig.

I'm not following?

[cpradio]

Well, assuming your forum will be like vBulletin and you will have vbCode (or something similiar), that function at the very end will probably save you a lot of time.

I will send you a PM so you can see exactly what I mean. As from just looking at it in that thread and the link, it leaves out a lot of information.

I already know how to do tags...
