 Hi all php experts,
 
 I would like to ask you all a question, I hope this is the right place
 to ask it.
 
 I'm writing a PHP extension now in c/c++. User uploads a file (could be POST
 or PUT method, but I can limit it to POST only). I need to capture the
 file data while being
 uploaded, without writing it to disk on the server. I need to process
 the data and (maybe,
 depending on a situation) send it somewhere else or save it to disk.
 Of course I know, that I can process the file
 after it has been uploaded (saved on disk on the server), but I would
 like to avoid it.
 I also need to do something opposite: I need to generate a file on the
 fly and send it
 to the user. All metadata of the generated file is known beforehand
 (e.g. size, name).
 
 I've been searching around for some time now and I could not find
 anything even close to the solution.
 Is there any example(s) or existing PHP extension that do(es) something
 like this (at least something simmilar) ?
 If you could give me any pointers that would be awesome.
 
 Thanks for your help 

The question I have is why? Should your upload fail for any reason you've got a 
half processed file that is non-recoverable.  No do-overs. If you stick to the 
standard processes with out the extension,

Upload
Save somewhere (or leave in temp upload folder)
Process
Send result back to user 
Unlink file

Generating the file and sending it to the user is also pretty standard

Create your dataset
Send appropriate headers
Send data
Close connection

For this, there usually isn't a need to save the file. You may run into issues 
streaming the data to certain browsers. 

Also one of the main downsides to your upload is high load situations or large 
file situations (where file size exceeds php's upload limit). 

My personal preference is to save that file to disk so that if needed I can 
work with it later ( if say the server load is high) and email the results to 
the user.

If you're looking to create a SQl table then most but not all browsers can use 
SQLite locally for data storage ( it does require newer browsers). 

You haven't stated the goal for this so other options could include sending csv 
or json data down to the browser and using jquery, angular or some other JS 
framework to manipulate that data may also be an option

Thanks for the message and help,
because I use jQuery autocomplete which has performance issue for thousands 
records due to network load data.
I want to load the data to local table to resolve performance issue, if it 
possible I can load to an array in the memory.


Thanks again for helping,

Regards,

I had exactly this situation, large list with the autocomplete. I cached the 
list to a JS file and ran the autocomplete from that. It works well if the list 
is relatively static which mine was. It will be tougher if the list is dynamic, 
but you could send the data down after the initial page load.
