php和Java的socket通信

通过php给Java发送请求,java给树莓派发送请求控制树莓派

进而通过网页就可以对所有模块进行控制

php代码

<?php
  $socket = socket_create ( AF_INET, SOCK_STREAM, SOL_TCP ) or die ( 'could not create socket' );
  $connect = socket_connect ( $socket, '127.0.0.1', 5678 );
  socket_write ( $socket, '1' . "\n" );
  $str = socket_read ( $socket, 1024, PHP_NORMAL_READ );  
  echo $str;
  socket_close($socket);
 ?>

java代码

控制切割视频的方法
