Is there a possibility this can be fixed in version 8? From http://phpsadness.com/sad/30 listed as an outright bug (I don't have the C skills to fix this. I am just raising this as an issue that has been a criticism of PHP for many years now with a new major version upcoming that could allow for a b/c of this significance to improve the language):
The ternary operator is left-associative and therefore behaves entirely incorrectly: $ cat ternary.php <?php echo (FALSE ? "a" : FALSE ? "b" : "c")."\n"; echo (FALSE ? "a" : TRUE ? "b" : "c")."\n"; echo (TRUE ? "a" : FALSE ? "b" : "c")."\n"; echo (TRUE ? "a" : TRUE ? "b" : "c")."\n"; ?> $ php ternary.php c b b b In any other language with a ternary operator, you can stack them and build an if-elseif-elseif-else expression: $ cat ternary.pl #!/usr/bin/perl -w use strict; print +(0 ? "a" : 0 ? "b" : "c")."\n"; print +(0 ? "a" : 1 ? "b" : "c")."\n"; print +(1 ? "a" : 0 ? "b" : "c")."\n"; print +(1 ? "a" : 1 ? "b" : "c")."\n"; $ perl ternary.pl c b a a -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
