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 $hear; if("byern"==$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 "Linkn"; while($con){ $hear=socket_read($socket,1024); echo $hear; $words=fgets(STDIN); socket_write($socket,$words); if($words=="byern"){break;} } socket_shutdown($socket); socket_close($sock); ?>
