1. http://www.php.net/manual/en/control-structures.alternative-syntax.php shows an alternative syntax for loops:
foreach($list as $item)
{
echo $item;
}
can be done as:
foreach($list as $item):
echo $item;
endforeach
2. if your server has short tags enabled, you can do this:
<? $somevar="hello"; ?> <?=$somevar?>
