Usage Example
|
No example needed really, just plug and chug. You can make it a little friendlier by looking accepting any file name, but to me it makes sense to only accept files with a particular name -- in this case, files[]. Just put as many inputs of type file with name= files[] in your html code as you like, and this script will process them all.
The usual caveats apply. Make sure that your PHP is configured correctly to accept large files if that's the way you swing. I use $HTTP_SERVER_VARS, which is deprecated, but screw me. Fix it if you like. Improve this code. Absolute free use is granted.
