In my opinion this exception is invaluable for validating arguments- for example providing strict typing a la C:

function tripleInteger($int)
    throw new
InvalidArgumentException('tripleInteger function only accepts integers. Input was: '.$int);
$int * 3;

$x = tripleInteger(4); //$x == 12
$x = tripleInteger(2.5); //exception will be thrown as 2.5 is a float
$x = tripleInteger('foo'); //exception will be thrown as 'foo' is a string
$x = tripleInteger('4'); //exception will throw as '4' is also a string
