Appending to / concatenating multiple strings in one call in PHP?

Question

I know you can assign to multiple variables in one call like so:

$varOne = $varTwo = "some value";

But is there a way append to multiple variables (strings) in one call?

Clearly this is incorrect syntax, but I was thinking something like this:

$varOne = "he's ";
$varTwo = "she's ";
$varOne, $varTwo .= "insane";

echo $varOne; // Outputs "he's insane"
echo $varTwo; // Outputs "she's insane"

Answer 1

There is no way to concatenate 'in one call' like this in php outside making your own function and calling it. Appending operators work on only one variable.

Answer 2

Not possible, not really. At best, you could use variable variables like so:

 foreach (array('varOne', 'varTwo') as $var) {
     $$var .= 'insane';
 }

Variable variables are a maintenance headache though, and by maintenance headache, I mean a kitten gets killed each time you use the construct, so beware.
