You have to have an increment statement, do you not?  Change the numbers to variables and add 1 each time through.  I think that is what you need to do.

that is an infinite loop...i think what you are looking for is:

 

<?php
for($n = 0;$n < 4;$n++){
  echo " <span>- <a href=\"news.php?go=view&id=$id\">$content</a> </span><br />";
}
?>

94770 itried that b4 didnt work...

 

thanks: rhodesa

that fixed it ..

What 94470 was saying works too...you have to increment a counter in order for a while loop to work.

 

You had while(1<=4)

 

But 1 is ALWAYS less than 4...so it'll never stop =)

 

What you want is

 

<?php
$i=0;

while($i<=4){
echo $i."<br>"; 

$i++;
}
?>

 

This should give you a better example how a while loop works.

hmm thanks for that i thought that increment thng worked only for the for,foreach loops hmm i my consider that from now on... well i kinda changed the code again and used this instead then just limited the results on the sql query itself... which is what i used to do...

 

<?php
while($returned_data = mysql_fetch_row($result))
{
list($id,$descri,$content,$views,$date) = $returned_data;
  echo " <span>- <a href=\"news.php?go=view&id=$id\">$content</a> </span><br />";
}
?>

I probably should have given an example to clarify...
