一个简单的自动发送邮件系统(一)_php基础
一个简单的自动发送邮件系统
php的另一个强大的特征就是他有能通过html的表单修改变量的能力,通过这些变量,我们可以实现很多任务,包括象:发送wed-based的邮件,把信息输出给屏幕,从数据库中读取和传递数据。下面让我们构建一个小型的自动发送邮件系统,来演示这个能力。
让我们假设有这样一个html的表单:
--------------------------------------
|
--------------------------------------
把这个文件存为moreinfo.html
注意 action指向文件:email.php3 下面就是email.php3文件:
--------------------------------------
/* this script will handle the variables passed from the moreinfo.html file */
PRINT "
";
PRINT "Thank you for your interest.
";
PRINT "We will send information to $email, and have noted that you like $preference.";
PRINT "
?>
--------------------------------------
把上面的文件存为email.php3
当用户在表单里键入他们的name和email,点击“send it!”按钮,表单就会调用email.php3文件,依次如下显示:(这里我们假设person'name 是bill, email地址是bgates@devshed.com ,选择了apples):
--------------------------------------
Hello, Bill.
Thank you for your interest.
We will send information to bgates@devshed.com, and have noted that you like Apples
--------------------------------------
这样我们的工程还没有完成,由于我们不知道谁曾经插入了一些信息,也没有什么实质性的事情发生过,我们没有办法给bill发信。
为了减少用手工发送标准email的负担,我们可以使用php的mail()命令。
语法:void mail(string to, string subject, string message, string add_headers);
·to---寄出电子邮件到指定的邮件地址
·subject 表示主题
·message 为信件内容
·additional_headers 可省略,表示其它的邮件文件头。
因而,如果我们把这个命令插入到print语句之后,我们就可以自动的给用户和网站的斑竹发信了,让我们知道谁需要这些信息。
--------------------------------------
mail("$email", "Your request for information", "$namen
Thank you for your interest!nWe sell fresh corn daily over the Internet!
Place your order at http://www.buycorn.com,
and receive a free package of $preference!");
mail("administration@buycorn.com",
"Visitor request for info.","$name requested for information.n
The email address is $email. n The visitor prefers $preference.");
?>
--------------------------------------
注意:mail()函数仅仅在SENDMAIL装在服务器上才可以使用,所以,在大多数情况下,使用前先确定是否可以使用。
但是当有很多人填写了信息,作为管理人员,你不可能一一浏览信件,你可以用数据库来跟踪究竟有多少人选择apples,多少人选择了oranges?这样的数据库有很多种,其中最快之一的就是mysql。
再下一篇文章中,我将给大家介绍如何将php和mysql结合起来使用。

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

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.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.
