Phpsocket communication (tcp/udp) instance analysis, socketudp_PHP tutorial

Phpsocket communication (tcpudp) instance analysis, socketudp. Phpsocket communication (tcpudp) instance analysis, socketudp this article describes the phpsocket communication (tcpudp) method. For your reference, the details are as follows: 1. Analysis of php socket communication (tcp/udp) instances during socket_bind, socketudp

This example describes the php socket communication (tcp/udp) method. We will share this with you for your reference. The details are as follows:

Note:

1. when socket_bind is used, the IP address cannot be a real loopback address, for example, 127.0.0.1.
2. nohup php server. php>/var/tmp/a. log 2> & 1 &

I. udp

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);?>

II. TCP mode

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);?>
