(Why? Doesn't make sense to me.) In fact, it always emits the X-Powered-By line. Normally, however, this line becomes a part of the HTTP header and is transparent to the end user. You end up seeing it in your browser only if something goes wrong during the startup phase of PHP, usually due to a parse error of the php.ini file, or an invalid or missing extension referenced from it. This results in emitting an error message, which the Web server identifies as the HTTP header; The X-Powered-By line that follows is then considered as a part of the document body, which is why you end up seeing it in your browser. This problem occurs only under Windows, since Windows considers stderr output (through which the error message is reported) no different from stdout output. PHP 4.0.1 solves this problem by presenting a Windows message-box that describes the error, which you can hardly miss. Once you notice what the error is and fix it (again, most probably by fixing php.ini) - the problem will be gone. Zeev -- Zeev Suraski <zeev@zend.com> http://www.zend.com/
