Re: if variants

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;

Ack! I forgot to mention parentheses! I've got to go add slightly to my "Appendix" section, now.

Personally I like:

if ($i>1) {
   $a = function_that_may_fail();
   $i = ($a) ? $i+1 : 1;
}

I find that the only time I really use "and" and "or" are with carp/croak/warn/die. But that's just me.

At worst:

do { $a=function_that_may_fail(); $i= $a ? $i+1 : 1; } if ($i>1)
