php file upload

Question

anyone can explain file upload process in PHP. I mean what happens in backend internally.

like saving with temp name, moving to upload folder etc.

I want it's step by step working.

Thanks

Good question. I don't quite understand it myself. It seems like a web-server do receive POST data, and then call PHP. PHP core some prepdocessing (decode MIME parts, save file into temporary location) and then user php code being called. — Your Common Sense

May be I am wrong, but there is nothing of PHP internals, e.g. when and how MIME data being decoded, etc
