Simple for loop and table problems

[chrisdee]

The simple script below prints out a table with numbers from 0
to 100. With the if sentance if($i%20==0) i break off the table rows after 20 cells. Any ide why this loop doesnt echo 0, 20 40, 60, 80 ?

<? # For loop that prints out a table
echo "<table border=1>";
for($i=0; $i<100; $i++) { # Loops through numbers from 0 to 100
 if($i%20==0) { # Breaks of table rows after 20 cells
  echo "</tr>";
 }
 else {
  echo "<td>$i</td>"; # Prints out the result
 }
}
echo "</table>";
?>

I do not see any beginning <tr> s that could be your problem

Iv tried that, but it's not the reason. The must be something else.

try this then

<? # For loop that prints out a table
echo "<table border=1><tr>";
for($i=0; $i<100; $i++) { # Loops through numbers from 0 to 100
if($i%20==0) { # Breaks of table rows after 20 cells
  echo "<td>$i</td></tr><tr>";
}
else {
  echo "<td>$i</td>"; # Prints out the result
}
}
echo "</table>";
?> 

That works for me, if it does not for you, then I have no idea.

edit:
Actually this code would probable be better

<? # For loop that prints out a table
echo "<table border=1><tr>";
for($i=0; $i<100; $i++) { # Loops through numbers from 0 to 100
  echo "<td>$i</td>"; # Prints out the result
if($i%20==0) { # Breaks of table rows after 20 cells
  echo "</tr><tr>";
}
}
echo "</table>";
?>
