php socket通信(tcp/udp)

注意　

　　1.在socket_bind的时候ip地址不能真回环地址如127.0.0.1

　　2.server.php后台跑起来的时候　nohup php server.php > /var/tmp/a.log 2>&1 &

一： udp 方式

1) server.php

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

<?php   //error_reporting( E_ALL ); set_time_limit( 0 ); ob_implicit_flush(); $socket = socket_create( AF_INET, SOCK_DGRAM, SOL_UDP ); if ( $socket === false ) {     echo "socket_create() failed:reason:" . socket_strerror( socket_last_error() ) . "\n"; } $ok = socket_bind( $socket, '202.85.218.133', 11109 ); if ( $ok === false ) {     echo "socket_bind() failed:reason:" . socket_strerror( socket_last_error( $socket ) ); } while ( true ) {     $from = "";     $port = 0;     socket_recvfrom( $socket, $buf,1024, 0, $from, $port );     echo $buf;     usleep( 1000 ); } ?>

 2) client.php 

?

1 2 3 4 5 6 7

<?php $sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP); $msg = 'hello'; $len = strlen($msg); socket_sendto($sock, $msg, $len, 0, '202.85.218.133', 11109); socket_close($sock); ?>

 

一： TCP 方式

1)server.php

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

<?php   //error_reporting( E_ALL ); set_time_limit( 0 ); ob_implicit_flush(); $socket = socket_create( AF_INET, SOCK_STREAM, SOL_TCP ); socket_bind( $socket, '192.168.2.143', 11109 ); socket_listen($socket); $acpt=socket_accept($socket); echo "Acpt!\n"; while ( $acpt ) {     $words=fgets(STDIN);     socket_write($acpt,$words);     $hear=socket_read($acpt,1024);     echo $hear;     if("bye\r\n"==$hear){         socket_shutdown($acpt);         break;     }     usleep( 1000 ); } socket_close($socket) ?>

 2) client.php

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

<?php $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); $con=socket_connect($socket,'192.168.2.143',11109); if(!$con){socket_close($socket);exit;} echo "Link\n"; while($con){         $hear=socket_read($socket,1024);         echo $hear;         $words=fgets(STDIN);         socket_write($socket,$words);         if($words=="bye\r\n"){break;} } socket_shutdown($socket); socket_close($sock); ?>
