Php serves as the server to accept data. This post was last edited by chaoyangqq from 2014-03-at the bottom layer. what teammates do is to read only the data in the http message data, how should I communicate with him! I tried to use curl to read data but it was unsuccessful. curl_setopt ($ ch, & nbsp; CURLOPT_URL, 19 php was used to receive data on the server.

What the bottom layer does not understand is that teammates only want to read the data in the http packet data. how should I communicate with him! I tried to use curl to read but failed.
Curl_setopt ($ ch, CURLOPT_URL, "192.168.16.254: 8080 ");
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 );
// Save it to a string or output it to the screen, 1 hidden
Curl_setopt ($ ch, CURLOPT_TIMEOUT, 1); // obtain the information of up to one second
Curl_setopt ($ ch, CURLOPT_HEADER, 0 );
Echo $ output = curl_exec ($ ch );
Curl_close ($ ch );
For guidance.
------ Solution --------------------
The php server that receives client data can be obtained through $ _ POST, $ _ GET, $ _ REQUEST. The client needs to use the corresponding $ _ post and $ _ get to submit data. $ _ REQUEST seems to be okay.
As for the difference between $ _ POST and $ _ GET, you can find too many items on Baidu.
$ _ POST, $ _ GET returns the parameters passed by your client. you can process these parameters to complete the function. to return data to the client, you only need echo.
I am working on a php server Recently. I don't know why. I cannot GET data using $ _ POST, $ _ GET, $ _ REQUEST. So I found $ GLOBALS [$ HTTP_RAW_POST_DATA] and file_get_contents ("http: // input") to get the data.
Both of the above methods can obtain the first type of data in the post request from the client.
I used the second $ request = file_get_contents ("http: // input") to get the post parameters from the client.
I only need to work on the php server temporarily. I don't know much about it because I haven't learned through the system. I just got the php server ready. Hope to help you.

Echo $ output = curl_exec ($ ch); no data?
Possible causes
1.192.168.16.254: 8080 this page has no output.
2. curl connection error. you can add curl_error to view the error.
if(curl_errno($ch)){
echo 'curl error:'.curl_error($ch);
}
