Uploading files with ActionScript 2.0 & PHP
If you have to write some server side code (such as PHP) to receive a file being uploaded through HTTP POST from ActionScript 2.0 (such as in Flash 8 - here is a good tutorial) - the $_FILES['Filedata'] variable which PHP can access is something defined in the Flash internals - not something a Flash developer sets.
Hopefully this will save some PHP and Flash developers a few hours of headache.
