Limiting While Loops

Weird1993 · #1 Jul 8th, 2007, 16:34

Ok Webforumz, I need help... I'm a little stuck... Can anyone help me figure out how to use a while loop and limit the amount of rows of data it outputs? Basically, display the last 3 or so entries.

umm, some code might help. Which programming language are we using?

oops, forgot. PHP is what I'm using. The point is I'm trying to see if there is a code for it.

Shouldn't you be doing that in your sql query?

Something like

PHP: Select all


$GetLast3 = mysql_query("select * from table order by id desc limit 3");

ummm. The while loop is the limit for how many lines of data get output:

PHP: Select all


$i=0;
while($i < 3) {
  // output stuff
  $i++;
}

but actually a for loop is better for something like that:

PHP: Select all


for($i=0;$i<3;$i++) {
  // output stuff
}

I hope I'm understanding your question right.
