[Phplib-commit] CVS: php-lib-stable/php tree.inc,1.1.1.1,1.2

[Richard A. <ric...@us...>]

Update of /cvsroot/phplib/php-lib-stable/php
In directory usw-pr-cvs1:/tmp/cvs-serv4461

Modified Files:
	tree.inc 
Log Message:
A few enhancements to tree.inc:
resolve bug ID #450713 - check that the $k var contains something
Add minimal session-awareness to make the example in the docs work
fix a few undefined variable warnings
fix typos, whitespace, escaping '\' chars
It works fine for me in PHP3 and PHP4, but may still have a few issues.
