Syntax question 2

[Sleidia]

Hi again

Let's take the following if statement :

if ($a == 1 OR $a == 33 OR $a == 7) do_something();

Is it possible to do the same thing without repeating $a ?

Thanks for the help!

No.

You're performing three checks against the variable. You must reference the variable three times.

how about

if (in_array($a, array(1,7,33)){
 do_something();
}

Thanks Jpadie

... but it wouldn't work in the following case :

if ($a > 1 AND $a < 33 AND $a != 11) do_something();

We would still have to repeat $a.

Now, I think that if such a syntax existed, it couldn't be shorter than the current syntax anyway. I bet this is the reason why it wasn't implemented in PHP.
