How can one upload multiple files with php?
 

this is because of the time it takes to upload the files. if you upload too many at once your php script has a good chance of timing out while it waits for all of the files to upload and die. this is especially true if the files are big.

set the time limit on your script to zero so that your script doesn't timeout.

You might also want to make sure your upload limits are large enough for the file sizes you will be allowing.
