php如何验证smtp信息的正确
最近在用dede做站,看到后台有启用smtp方式发送邮件的设置,但没有验证。请问各位PHP大神,如何验证填写的smtp信息是否正确,验证包括端口、用户名、密码?求php代码实现,并输出这些错误信息,100分奉上!感谢。

dede的启用smtp方式发送邮件的设置,你是安装的插件吗?
我本地装的最新dede好像没这个功能设置哦
回楼上大牛,我只要能验证smtp信息是否正确就行,不需要做成dede插件。
//打开smtp服务器端口
$fp = @fsockopen($smtp_host, 25);
if (!$fp)
echo "Error: Cannot conect to ".$smtp_host."
";
$smtp = array( //1、EHLO,期待返回220或者250 array("EHLO ".$loc_host.$lb,"220,250","HELO error: "), //2、发送Auth Login,期待返回334 array("AUTH LOGIN".$lb,"334","AUTH error:"), //3、发送经过Base64编码的用户名,期待返回334 array(base64_encode($smtp_acc).$lb,"334","AUTHENTIFICATION error : "), //4、发送经过Base64编码的密码,期待返回235 array(base64_encode($smtp_pass).$lb,"235","AUTHENTIFICATION error : ") ); //5、发送Mail From,期待返回250 $smtp[] = array("MAIL FROM: <".$from.">".$lb,"250","MAIL FROM error: "); //6、发送Rcpt To。期待返回250 $smtp[] = array("RCPT TO: <".$to.">".$lb,"250","RCPT TO error: "); //7、发送DATA,期待返回354 $smtp[] = array("DATA".$lb,"354","DATA error: "); //8.0、发送From $smtp[] = array("From: ".$from.$lb,"",""); //8.2、发送To $smtp[] = array("To: ".$to.$lb,"",""); //8.1、发送标题 $smtp[] = array("Subject: ".$subject.$lb,"","");$result_str=""; //发送smtp数组中的命令/数据 foreach($smtp as $req) { //发送信息 @fputs($fp, $req[0]); //如果需要接收服务器返回信息,则 if($req[1]) { //接收信息 while($result = @fgets($fp, 1024)) { if(substr($result,3,1) == " ") { break; } }; if (!strstr($req[1],substr($result,0,3))) { $result_str.=$req[2].$result."<br>"; } } } //关闭连接 @fclose($fp); return $result_str; }
倒没有没弄过验证smtp的端口、用户名、密码,端口还好说,但用户名、密码的话,只能尝试去请求来判断了...
function smtp_sockopen_relay()
{
$this->log_write("Trying to ".$this->relay_host.":".$this->smtp_port."\n");
$this->sock = @fsockopen($this->relay_host, $this->smtp_port, $errno, $errstr, $this->time_out);
if (!($this->sock && $this->smtp_ok()))
{
$this->log_write("Error: Cannot connenct to relay host ".$this->relay_host."\n");
$this->log_write("Error: ".$errstr." (".$errno.")\n");
return FALSE;
}
$this->log_write("Connected to relay host ".$this->relay_host."\n");
return TRUE;;
}

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
