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127.0.0.1

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

//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

$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

//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

$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);

?>
