Ask php cli to parse HTTP request

php.internals

I have a file that contains a HTTP request, ``` GET /xxx.php Host: xxx Content-Type: xxx ... ``` I would like to ask PHP cli to parse the HTTP request from a file, and setup $_FILES, $_POST, $_SERVER etc. What should I do? I'm familiar with PHP extensions, so I'm capable of modifying SAPI myself. So far I've found sapi_post_entry, but I couldn't get the whole picture. Where's the entry point of request parsing?

Morning, Ordinarily, we don't parse that stuff, because the server communicates via CGI/FCGI or some other server specific interface (apache). The CLI server does though, I'd look there for inspiration ... there's also an HTTP parser included in there ...

I'm referring to PHP-FPM, what about that? On Wed, Nov 16, 2016 at 7:08 PM, Joe Watkins <pthreads@pthreads.org> wrote:

Maybe something like https://github.com/guzzle/psr7/blob/master/README.md? There are additional middlewares that can extract from a request and populate super-globals for legacy app support purposes. On 16 Nov 2016 11:50, "Aaron Lewis" <the.warl0ck.1989@gmail.com> wrote:

Thanks Marco. But I'm looking for the C implementation .. On Wed, Nov 16, 2016 at 8:43 PM, Marco Pivetta <ocramius@gmail.com> wrote:

One question then: why? Working userland impl, just use it. On 16 Nov 2016 16:01, "Aaron Lewis" <the.warl0ck.1989@gmail.com> wrote:

The Ultimate Web Scraper Toolkit over on GitHub can get you about 75% of the way there in pure userland in a few lines of application code with the WebServer class: https://github.com/cubiclesoft/ultimate-web-scraper/ Possible approach: $fp = fopen("/path/to/file.txt", "rb"); stream_set_blocking($fp, 0); $server = new WebServer(); // If you want to allow gzipped/deflated input. //$server->EnableCompression(true); // If you are actually processing file input... //$server->SetCacheDir("/path/to/cache/"); $client = $server->InitNewClient(); $client->fp = $fp; do { $result = $server->Wait(); if (count($result["removed"])) { // File contains an invalid request. // Maybe bail out more gently? echo "Invalid request.\n"; exit(); } } while (!$client->requestcomplete); // Now use $client's public variables 'cookievars' and 'requestvars' to load various superglobals. There isn't a pure structure though for $_GET and $_POST. ... is_uploaded_file(), move_uploaded_file(), sesssions, and other useful built-ins might also not work as expected. Hence the 75% metric from earlier.
