You're forgetting that both . and - have the same precedence, and are
left-associative operators.

> $str = "this is a test" . (int)5-1;

That means that you're running this:

$str = ( "this is a test" . (int)5 ) -1;

Put in type juggling, and the result is that the string is eval'ed as (int
0, so you output 0 - 1 = -1.

But you do need to use parenthesis to overcome the precendence:


$str = "this is a test" . ( 5 - 1 );

or even

$str = "this is a test" . (int) ( 5 - 1 );
