SMTP Error: Could not connect to SMTP host.
我用网页运行时正常,能发送,用命令运行php文件时报错,主要代码经检查无误,如下

function sendmail($setEmail, $setName, $body, $subject) {<br />	require_once("PHPMail/phpmailer.php");<br />	$mail = new PHPMailer ( true ); // the true param means it will throw exceptions on errors, which we need to catch<br />	$mail->IsSMTP (); // telling the class to use SMTP<br />	try {<br />		$mail->SMTPAuth = true; // enable SMTP authentication<br />		$mail->SMTPSecure = SBT_SSL; // sets the prefix to the servier<br />		$mail->Host = SBT_SMTP_HOST; // sets GMAIL as the SMTP server<br />		$mail->Port = SBT_SMTP_PORT; // set the SMTP port for the GMAIL server<br />		$mail->Username = SBT_SMTP_USER; // GMAIL username<br />		$mail->Password = SBT_SMTP_PASS; // GMAIL password<br />		$mail->AddReplyTo ( SBT_MAIL_FROM, SBT_MAIL_FROM_NAME );<br />		$mail->AddAddress ( $setEmail, $setName );<br />		$mail->SetFrom (SBT_SMTP_USER,SBT_SMTP_USER); //sender name<br />		$mail->Subject = $subject;		<br />		$mail->MsgHTML ( $body );		<br />		if (! $mail->Send ()) {//(这边没报错)<br />			echo "Message could not be sent. <p>";<br />			echo "Mailer Error: " . $mail->ErrorInfo;<br />			exit ();<br />		} <br />	} catch ( phpmailerException $e ) {<br />		echo $e->errorMessage (); //Pretty error messages from PHPMailer(就是这边输出错误的)<br />	} catch ( Exception $e ) {<br />		echo $e->getMessage (); //Boring error messages from anything else!<br />	}<br />}

问下是什么原因,目的是为了可以用linux计划任务来执行该PHP文件


------解决方案--------------------
错误代码呢?
------解决方案--------------------
php --ini 一下,看使用的ini是否和作为apache模块运行的php一致.
------解决方案--------------------
不可能,$mail->IsSMTP ();这个表明你已经设置了smtp发送了.
你现在的主要问题是找找看为什么socket连接不了smtp服务器.
防火墙也有可能.
------解决方案--------------------
wamp环境,应该是共用一份ini文件的.想再一次确定的话,php网页输出phpinfo(),看使用的ini文件,是否和这个一致.
命令:telnet smtp.gmail.com 465 ,确定能连接成功?
------解决方案--------------------
检查一下防火墙,另外再检查一下发送图片附件的代码
------解决方案--------------------
telnet都不行,肯定是你防火墙禁止了访问

What is a session in PHP, and why are they used?What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AM

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

What steps would you take if sessions aren't working on your server?What steps would you take if sessions aren't working on your server?May 03, 2025 am 12:19 AM

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
