See http://uk.php.net/manual/en/language.operators.comparison.php where the ?: operator is explained. > [And please excuse a slightly off-thread but related extension to > the question but I have seen similar in Javascript - namely --- > var evt = (evt ? evt : ((window.event) ? window.event : null); > is this the same notation or something else?] Yes, same basic notation -- the only minor difference is that the associativity is different, so nested ?: operators are evaluated in a different order.
