Anyone know of a good standalong PHP trackback app? There's got to be one out there somewhere. Or maybe a plugin or something from some app that can be adapted?
What is it that you want exactly? If you want to write your own script which is able to handle trackbacks, I believe the xmlrpc library is mostly used for this. You might wanna check that out.
Yeah, it looks like that's what I'm going to have to do. For the time being I'm using the standalone perl tool from the Movable-Type people. It's not php, which my site is written in, but it works and I'm not going to be that particular. Meanwhile, I decided to take the PHP based blog I patched together over a period of time and re-write it with all the bells and whistles I added here and there properly integrated. I'll build a PHP trackback utility into it so the problem will be solved long term there.
