Multiple ways todo an if statement?

I know the old
Code: Select all
if($statement == true)
{$statement = 2;
}
else
{$statement = 1;
}
But I remember reading a wierd method along time ago that (off the top of my head) was like
Code: Select all
if($statment == true){$statement = 2 ? $statement = 1;}

Yes, it works like:
Code: Select all
( Condition ) ? True-Value : False-Value;
So you could rewrite an assignment operation like you have above as:
Code: Select all
$statement = ($statement == true) ? 2 : 1;
I hope that helps!

I usually use a
http://php.net/switch in times when I am expected one of many different possible values.
For example
Code: Select all
switch ($action)
{
case 'delete' :
//run delete
break;
case 'login' :
//run login
break;
default :
//if no value has been matched
//run this
}

usually i would write
or the negative version
instead of
Code: Select all
if ($condition == true)
if ($condition != true)
if ($condition == false)
if ($condition != false)

Yes, the (condition) ? true : false; syntax is called the trinary operator or ternary operator. Same as C++

using that method also allows you to nest if statements elligibly, such as:
Code: Select all
<?php
$i_am_perfect = ($pointed_nose?($sexy_body?($fair_coplexion? true : false) : false) : false);
?>
