Just thought that it would be beneficial if the moodle core team could also put PHP Cross reference (using PHPXref) for Moodle 1.5.x and Moodle 1.6.x on this site:
http://xref.moodle.org/nav.html?_functions/index.html
Of course developers could also generate a local copy using PHPXref but I think there are still a lot of LIVE production sites that are using earlier versions of Moodle (and doing daily trouble-shooting, etc.) and it would be great to have Moodle 1.5.x and 1.6.x PHP Cross reference on a central site (like under moodle.org) so that developers could also use it to look up Moodle functions, etc.
Just my 2 cents. Thanks!
