Suggestions regarding Pear & PHP5

Since PHP5 has a very improved oo model, I think it would be a good idea to create a compatibility scheme for Pear projects. I would like to suggest the following: PHP4 = Requires PHP v4.x PHP4+5 = Works with both PHP v4.x and v5.x PHP5 = Optimized/rewritten to take full advantage of PHP5 Adding to this it would be nice if every package in the Pear project had a setting for this, plus official PHP releases it is verified to work with. Then it would be very simple to add a filter to the Packages section of pear.php.net. This filter will simply let me set the version of PHP I use and only list items that is verified to be compatible with it. Another very nice feature would be if it was possible to select x number of packages (those I plan to use) and then get a list of requirement for these packages. These requirements would be dependencies of other needed packages, what PHP needs (compile options) and php.ini settings. Unless PhpDocumentor already supports it, it would be very nice to be able to document these dependencies directly in the source code as well. Another Pear module could then be able to extract this documentation and thus quickly give me a dependency and requirement list for my installation. Would this be overkill you think? For me it would most likely save a lot of time testing packages to check if they work with my PHP, just to discover later into the project that features doesn't work with the PHP I use and thus risk to force me to restart development for parts of it. /Thomas
