in reply to if variants
regarding the precedence, you can also use the and and or variants who have lower precendence so that you can have assignements work.
Here's a rough example with nested ifs and an else
if ($i > 1 ) { if ($a = function_that_may_fail()) { $i++; } else { $i = 1; } }
can become:
$i > 1 and $a = function_that_may_fail() and $i++ or $i = 1;
He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.
