You're confusing brackets, braces, and parentheses.
Parentheses are like this
if($a > 5)
Brackets are used for arrays, like this:
$myArray[4] = "hello";
Braces are like this:
If($a > 5)
{
# this line is in a pair of braces
}
Take care,
Sina

Thanks for this, but when doing the one liner, don't we still have to use
the brackets? Your example was like this:
$b = 1 if $a >0;
But do we have to do it like this?
$b = 1 if ($a >0);
With All Respect,
