I have the $_POST['var'] variable that we get from the form.
We use it only to display data from it on the screen.
Is it possible to restart / shut down the server by sending a huge number of requests?

Please correct the question so that it describes the specific problem with sufficient detail to determine the appropriate answer. Do not ask a few questions at once. See “How to ask a good question?” For clarification. If the question can be reformulated according to the rules set out in the certificate , edit it .

  • @BOPOH, connected. "Lower" in the meaning of "put", "hang". And "overload" in it, only a softer version. - Qwertiy ♦
  • But this does not prevent the issue to be disgustingly formulated. What does "only to display data from it on the screen" mean? And preferably some code for this output. - Qwertiy ♦

It is impossible to overload a normally configured server in the chat mode with a simple request, the HTTP server has a restriction, and in response to a request that is too long, it will generate error 413.

You can overload with a large number of requests at one time, than the server can withstand.

Or in the case when the request starts some "undocumented" process (ie, there are viruses on the server or a vulnerability is discovered).
