本文实例讲述了php socket通信(tcp/udp)方法。分享给大家供大家参考，具体如下：

注意

1.在socket_bind的时候ip地址不能真回环地址如127.0.0.12.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

<?php//error_reporting( E_ALL );set_time_limit( 0 );ob_implicit_flush();$socket = socket_create( AF_INET, SOCK_DGRAM, SOL_UDP );if ( $socket === false ) {  echo "socket_create() failed:reason:" . socket_strerror( socket_last_error() ) . "";}$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

<?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);?>

二： TCP 方式

1)server.php

<?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!";while ( $acpt ) {  $words=fgets(STDIN);  socket_write($acpt,$words);  $hear=socket_read($acpt,1024);  echo $hear;  if("bye"==$hear){    socket_shutdown($acpt);    break;  }  usleep( 1000 );}socket_close($socket)?>

2) client.php

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