Please please please please don't do this!

First of all, I don't know why you would use the print *function* when 
you can also use the echo language construct (better and faster). But 
that's not that important; it's not bad to use it, just imo a bit ugly 
(pet peeve ;)).

But more importantly:
"$variable" is completely and utterly useless. You're basically creating 
a string, interpolating a variable in it, and adding no more content. 
This is effectively the same as saying:
print("".$var."")
Does that look right to you? To me it looks... wrong...

Why not just a simple:
echo $var;
or
print($var) if you really must.

And if you really really must cast the variable to a string, you can 
always use the explicit:
(string) $var
