-1 for worrying about this, both the following are fine with me:
$var . ' string'
"$var string"
On a related note, we should discuss arrays in strings too:
"a $arr[foo] b"
"a {$arr['foo']} b"
'a ' . $arr['foo'] . ' b';
I prefer the first but it will/may make some people feel not surrounding
keys with quotes is okay, it's not unless in a string otherwise
eventually a E_NOTICE error is created. Concatenation seems appropriate
here.
