While it's apparently not always required, I always reccommend (and always
do it personally) that you use a bracket around every function.
So it should lool like this:
<?
error_reporting(E_ALL);
for( $i=0; $i<10; $i++ )
{
for( $j=0; $j<10; $j++ )
{
$res = $i * $j;
print(" result = $res <br>");
}
}
?>
It makes it easier to see where the loops begin and where they end, and it
stops most types of errors from appearing.
