A long-troubled question, ask the master to point the way.
An end device that sends a request to the server
For example:
192.168.1.9:8000/response?serial=235678979
Requires the response data to be
aaa=333
bbb=444
Realtime=1

When responding with an application, it is normal and can be used.


Use PHP programmer, the response part of a bit more things, according to the terminal equipment can not be used properly!


With the Wireshark grab packet, some more PHP header information, how to remove these redundant headers.


Note, the device is also normal when the direct response is changed. It is not normal for PHP to handle it.


------Solution--------------------
These are standard HTTP interactions that are required for header data. If you want to do it in PHP,
1, modified Apache and PHP do not output header data (specific Baidu, Google)
2, modify the terminal code, according to the HTTP 1.1 protocol to come out data.
------Solution--------------------
Write to the terminal with a file function, there is no HTTP header
The key is how to know which terminal
------Solution--------------------
HTTP header is the Web server is responsible for returning, do you want the Web server to receive HTTP requests do not return HTTP headers? I'm afraid I can't, why don't you use PHP as a socket server.
------Solution--------------------
Agree upstairs Silly Bird fly first
This is a Web server thing, in fact, your response needs not the HTTP protocol, that is, you have to write a headless server ....
