<?php$YourEmailAddress = "";error_reporting (E_ALL ^ E_NOTICE);$post = (!empty($_POST)) ? true : false;if($post) { function ValidateEmail($email){ $regex = "^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$^"; $eregi = preg_replace($regex,'', trim($email)); return empty($eregi) ? true : false; } $subject = "Quick contact from home page"; $to = $YourEmailAddress; //trim($_POST['to']); $email = trim($_POST['user-email']); $message = stripslashes($_POST['user-message']); $error = ''; $Reply=$to; $from=$to; if(!$email) { $error .= '请输入邮箱地址<br />'; } if($email && !ValidateEmail($email)) { $error .= '请输入验证过的邮箱<br />'; } if(!$message || strlen($message) < 3) { $error .= "请输入留言信息<br />"; } if(!$error) { $messages="From: $email <br>"; $messages.="Email: $email <br>"; $messages.="Message: $message <br>"; $emailto=$to; $mail = mail($emailto,$subject,$messages,"from: $from <$Reply>\nReply-To: $Reply \nContent-type: text/html"); if($mail) { echo '成功'; } } else { echo '<div class="error">'.$error.'</div>'; }}?>

里面有连接db,插入db的教程。
你没有说明是什么数据库,所以没法写代码
看下php的pdo
数据库是远程服务器。 这种架构不合适,要避免这么个架构。因为连接不可靠不稳定,性能也不行。
mysqlconnect函数不是有服务器地址。用户名密码。吗。你用这个连接。。其它都一样

好了 - - 我知道了。 谢谢大家参与。我结贴
大神从C++转PHP? 嗯。 做web了。 有掉费劲。 刚做web一个周。。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
