Joao is correct; the book is not. It's an excellent book, but as with any, there are mistakes: it lists both != and ~= as being assignment operators, when != is actually a comparison operator and has no effect when used in an assignment context, and ~= doesn't even exist in PHP at all. I think they were typos for ^= and |=. > therefore using the logic if ($val =="abc") { means if the value of $val is > equal to "abc" then ... > while if ($val = "abc") means assign the value of abc to $val and then > execute the insides of the curly braces.
