set_time_limit()

[freebie]

Hi,
I'm hoping someone knows whether "set_time_limit()" is needed for a file upload script that's accepting a large file (15-20 M😎. Here's a quote from the manual.
"Note: The set_time_limit() function and the configuration directive max_execution_time only affect the execution time of the script itself. Any time spent on activity that happens outside the execution of the script such as system calls using system(), the sleep() function, database queries, etc. is not included when determining the maximum time that the script has been running. "

Since waiting for the file to upload is not actual script processing time, I would think it wouldn't be necessary. Is that correct?

Also, I couldn't seem to figure out if set_time_limit() is allowed to accept a value larger than what is set in php.ini for the max_execution_time.

Thanks for any help

I think I found what I was looking for which is max_input_time, which by default is -1 (which is no limit), meaning the script won't timeout while the file is uploading, and thus the only controlling variable will be the max_upload_size and max_post_size
