php获取socket连接的详细信息
php使用socket调用http和smtp协议实例小结本文实例讲述了php使用socket调用http和smtp协议。分享给大家供大家参考，具体如下：
socket发送HTTP请求
http协议请求报文格式
get
|
|
## 请求方法 请求文件路径?查询字符串 HTTP/协议版本号## Host: 主机名:端口号## Connection:close |
post
|
|
## 请求方法 请求文件路径 HTTP/协议版本号## Host: 主机名:端口号## Content-type: application/x-www-form-urlencoded## Content-length： 查询字符串长度## Connection: close## 查询字符串 |
api.php
|
|
<?phpecho $_SERVER["REQUEST_METHOD"]."<br/>";print_r($_REQUEST); |
fsocketopen发送get请求
|
|
<?php$url = "api.php";$host = "127.0.0.1";$port = 8080;$param = ["name"=>"zhezhao","age"=>23];$url .= "?".http_build_query($param);$socket = fsockopen($host,$port,$errno,$errstr,10);$request = "GET /${url} HTTP/1.1\r\n";$request .= "Host:${host}:{$port}\r\n";$request .= "Connection:close\r\n\r\n";fwrite($socket,$request);echo "<b>Request:</b><br/>".str_replace("\r\n","<br/>",$request);echo "<hr/><b>Response:</b><br/>";$response = "";while ($out = fread($socket, 2048)) { $response .= $out;}echo str_replace("\r\n","<br/>",$response);fclose($socket); |
sockets扩展发送post请求
|
|
<?php$url = "api.php";$host = "127.0.0.1";$port = 8080;$param = ["name"=>"zhezhao","age"=>23];$data = http_build_query($param);$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);socket_connect($socket, $host,$port);$request = "POST /${url} HTTP/1.1\r\n";$request .= "Host:${host}:{$port}\r\n";$request .= "Content-type:application/x-www-form-urlencoded\r\n";$request .= "Content-length:".strlen($data)."\r\n";$request .= "Connection:close\r\n\r\n";$request .= "${data}";socket_write($socket,$request);echo "<b>Request:</b><br/>".str_replace("\r\n","<br/>",$request);echo "<hr/><b>Response:</b><br/>";$response = "";while ($out = socket_read($socket, 2048)) { $response .= $out;}echo str_replace("\r\n","<br/>",$response);socket_close($socket); |
socket发送smtp请求
首先通过socket连接到smtp服务器，例如smtp.163.com 25，然后实现smtp发送邮件的必须参数即可。
HELO 主机名
AUTH LOGIN base64编码之后的发件人邮箱
base64编码之后的密码
##填写信封
MAIL FROM:<发件人邮箱>
RCPT TO:<收件人邮箱>
##填写信件内容
DATA
MIME-Version:1.0
To: 收件人邮箱
From: 发件人邮箱
Subject： 邮件主题邮件内容
fsocketopen发送邮件
fsocketopen和pfsocketopen是php机制本身的函数，可以直接调用，不需要安装扩展。以上两个函数可以打开一个网络连接或者一个Unix套接字连接，然后我们可以使用fwrite,fread,fclose,feof等函数直接操作该网络连接。

<?php$user = "root@163.com";$password = "root";$mailto = "1234567@qq.com";$subject = "fsocketopen发送邮件";$body = "收到邮件了么，亲";$sock = fsockopen("smtp.163.com",25);fputs($sock,"HELO localhost\r\n");echo fgets($sock, 512)."<br/>";fputs($sock,"AUTH LOGIN ".base64_encode($user)."\r\n");echo fgets($sock, 512)."<br/>";fputs($sock,base64_encode($password)."\r\n");echo fgets($sock, 512)."<br/>";fputs($sock,"MAIL FROM:<${user}>\r\n");echo fgets($sock, 512)."<br/>";fputs($sock,"RCPT TO:<${mailto}>\r\n");echo fgets($sock, 512)."<br/>";fputs($sock,"DATA\r\n");echo fgets($sock, 512)."<br/>";$header = "MIME-Version:1.0\r\n";$header .= "To: ${mailto}\r\n";$header .= "From: ${user}\r\n";$header .= "Subject: ${subject}\r\n";fputs($sock, $header . "\r\n" . $body);echo fgets($sock, 512)."<br/>";fputs($sock, "\r\n.\r\n");echo fgets($sock, 512)."<br/>";fputs($sock,"QUIT\r\n");fclose($sock); |
sockets扩展发送邮件
sockets扩展的功能更加强大，可以搭建tcp/ip服务器，不过我们使用smtp协议发送邮件的例子，只需要使用到socket客户端的功能。

<?php$user = "root@163.com";$password = "root";$mailto = "1234567@qq.com";$subject = "sockets扩展发送邮件";$body = "收到邮件了么，亲";$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);socket_connect($socket, "smtp.163.com",25);socket_write($socket,"HELO localhost\r\n");echo socket_read($socket, 512)."<br/>";socket_write($socket,"AUTH LOGIN ".base64_encode($user)."\r\n");echo socket_read($socket, 512)."<br/>";socket_write($socket,base64_encode($password)."\r\n");echo socket_read($socket, 512)."<br/>";socket_write($socket,"MAIL FROM:<${user}>\r\n");echo socket_read($socket, 512)."<br/>";socket_write($socket,"RCPT TO:<${mailto}>\r\n");echo socket_read($socket, 512)."<br/>";socket_write($socket,"DATA\r\n");echo socket_read($socket, 512)."<br/>";$header = "MIME-Version:1.0\r\n";$header .= "To: ${mailto}\r\n";$header .= "From: ${user}\r\n";$header .= "Subject: ${subject}\r\n";socket_write($socket, $header . "\r\n" . $body);echo socket_read($socket, 512)."<br/>";socket_write($socket, "\r\n.\r\n");echo socket_read($socket, 512)."<br/>";socket_write($socket,"QUIT\r\n");fclose($sock); |
