Php cannot get the POST value-php Tutorial

Php cannot obtain the POST value. it is okay to submit a form on a webpage and send it to php.

Now the client is sent in c ++,
@ File_get_contents ('php: // input'); you can get it! Show q = test

However, $ _ POST ['Q'] cannot be obtained. $ _ POST array is empty

The entire request header is:
POST/xxx. php? Ent_id = xxxx & from = xxhttp/1.1
Connection: Keep-Alive
User-agent: Tsl/0.1
Content-Length: 6
Host: 127.0.0.1

(However, the same request can be sent to another server)

Thank you!

It should not be related to this...

If you want to get the result using $ _ POST, you must have Content-Type: application/x-www-form-urlencoded.

Yes, php $ _ POST requires ContentType to be parsed.
