How do I simplifiy: if 1 then var = yes else var = 2

I am trying to pull out of the deep corners of my brain how to do:

if ($var = 1) {
$secondvar = hi;
}
elseif ($var = 2) {
$secondvar = bye;
}

PHP:

in a single line, I thought i remember some shorthand way of doing it. (possibly using ? or : in the code)

 

$secondvar = $var == 1 ? 'hi' : 'bye';

PHP:

 

ahhh thanks a million...

 

is it possible to add a third part?
so simplifying:

if ($var == 1) {
$secondvar = hi;
}
elseif ($var == 2) {
$secondvar = bye;
}
elseif ($var == 3) {
$secondvar = good luck;
}

Code (markup):

 

I don't think you can do three, it's straight boolean I'm pretty sure. Any real reason you want to do it like that though? A lot of coders have never seen that before and most people just do:

if ($var)
  echo 'blah';
else
  echo 'blah2';

PHP:

It's just a bit easier to read in the long run I think.

 

Dude, you need to balance between being lazy and keeping the code readable
But yes, you could do that if you want.

$secondvar = ($var == 1) ? "hi" : (($var == 2) ? "bye" : "good luck");

Strictly speaking it needs another check for ($var == 3) because your last statement was an 'elseif' not plain 'else'.

 

Couldn't agree more. I hate messy code.

 

IMO I'd use a switch struture.

 

Or even arrays.

$foo = array(
    1 => 'hi',
    2 => 'bye',
    3 => 'good luck'
);

$secondvar = isset($foo[$var]) ? $foo[$var] : 'default';
