Php VS Java for Multiple file uploads simultaneously

Requirements:

1) Only multiple Images, and small files will be uploaded.

2) Upload progress tracking. 3) No flash, no prebuilt library, trying to learn here.

Problems:

I tried PHP before, but the problem was APC allows only one file to be tracked at a time, so i cannot upload multiple files at the same time, like in rapidshare or mediafire which I am looking to implement. So i looked into Java, And it all开发者_运维知识库ows me to control file upload section completely down to the bit patterns and I know facebook uses that too so sounds like a good option.

So what do youll suggest me to do? Continue with PHP, some alternative or shift to JSP? If I should continue with PHP how?

What do you know better? What is the rest of your web site built in?

Those are better questions to answer than trying to figure out which language is better for this task. (They'll both work fine.)
