I don't have to deal with PHP directly but to me it just doesn't feel right when for example you learn about financial websites being built in PHP (as in an HN submission the other day). All these strings being accidentally treated as integers or floats and vice versa, without a decent way of handling errors, it feels like building a skyscraper on a fault line and not worrying about making it earthquake proof. Even if I'll never have to set foot in it, I'll still complain.
