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
<?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
<?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!\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
<?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);
?>
