come creare un area per l upload in php

allora io vorrei creare un area di upload tipo quella di av solamente che deve essere in inglese e, una volta uplodato il file dare il link di dove è stato caricato il file, inoltre vorrei che che il peso massimo di ogni file non sia superiore a 30 mb, quest ultima non è indispensabile ma servirebbe molto grazie molte.

lo vuoi multiplo come su altervista o uniformo?

edit:
cioé...
multiplo che puoi uploadare piú file contemporaneamente
uniformo che ne puoi uploadare solo uno

vorrei che si debba uplodare 2 file uno .swf e un altro che abbia un estensione del tipo ,jpg .png e estenzioni di immagini molto usate grazie mille

questo é il file principale: (quello che ti fá uploadare i file)
