Mozilla 7.1 renders code examples in the PHP manual
incorrectly, while IE6 renders them correctly.
For example compare the difference between these two
browsers for the code examples in http://www.php.net/manual/en/language.types.boolean.php
I susect this difference was not intended, nor desired
I don't know of a Mozilla 7.1 browser. You are either speaking about Netscape or Mozilla 1.7. I have tried the page you mention with my Mozilla 1.6 and Firefox 0.9.1 and had seen no problem.
