But $null is a variable. What if you set it to e.g. 0 instead of null?

Maybe it complains about the ampersand character before function call? Try to disable E_STRICT error reporting. But this shouldn't be a fatal error.

if no txtbody, then the function _addHtmlPart () is passed $null (equal to null: $null = null). Why in the PEAR repository is the code that does not work on some level error reporting (E_STRICT) - if we disable this error rate, we might miss something important. Do not you think it's a little strange that the package Mail_Mime,. which implements the core functionality of our system, there are errors of incorrect use of the transfer value by reference. Interperator PHP tells us that we can not pass null here. -Why will not solve the problem, rather than trying to get rid of her symptoms?

This bug has been fixed in SVN. If this was a documentation problem, the fix will appear on by the end of next Sunday (CET). If this was a problem with the website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
