Operator ternary

Look at the operator ternary:

$flag = true;

($flag)?($a = "yes"):($a = "no");

Now i want to have multiple statements in my operator ternary something like
(does not work!!!):

($flag)?($a = "yes";$b="yes"):($a = "no";$b="no");

One way to make this work is:

($flag)?($a = "yes" and $b="yes"):($a = "no" and $b="no"); but to me this is
not logical.

Does somebody have any ideas about this?

regards,

Marcel

The ternary operator is not designed to execute code. It's designed for
uses such as:

$a = $flag : "yes" : "no";

i.e. assigning a value dependent on the logical state of $flag. It just
so happens that your code above works, because '$a = "yes"' evaluates to
a value, and so can be used in the ternary operator.

Why not just use if? That's what it's there for! And it's far more
obvious what's going on than trying to cram a load of code onto one line.

if ($flag)
{
..
}
else
{
..
}

You're supposed to use it like this:
$a = $flag ? 'yes' : 'no';
$b = $flag ? 'yes' : 'no';
$c = $flag ? 'michael' : 'knight';
etc.. Or like Oli said, use if statement...
