PHP receives JSON data sent by Android?

Android JSON PHP

$response = Array ();
Include ("conn.php");
$conn =mysql_open ();
$sql =mysql_query (' Set names UTF8 ');
mysql_query ($sql);
if (isset ($_post[' name '))} {..... ........... Why does it prompt for undefined name? Name is the one that Android sent over.

Aren't you json? What is the content you send? How do you know that? What is the message of the error? That's a hint.

To see if it gets to name, you can tell the value to save to the file. Because the Android program once opened to call your PHP file, you open the file, sure sister paper

Run the Android program first and then open the browser

It turns out that my Android program is having a problem, and the IP address is incorrectly written in the URL. But also strange, I was a laptop to see a temporary LAN, and then the phone connected to this network, so my IP is written on this network IP, but it is proved to write the computer connected to the route of the network IP.

$data = file_get_contents ("Php://input") in order to receive data, because PHP only recognizes application/x-www.form-urlencoded standard data types by default, so the type of text Content such as/xml or soap or application/octet-stream cannot be parsed.
