php socket通信(tcp/udp)

php socket通信(tcp/udp)
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

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)
	?>

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);
   ?>
