mailfunction in php is a built-in function for sending emails, but if you really want to use the mail function to send emails, you must give your systemInstall the sendmail component. Now I encountered the problem that mail cannot send emails. Let’s take a look at the solution.
The previous server was transferred here Later, I found that the website could not send emails using mail(), but I found that sendmail has been installed. If sendmail is not installed, it can be executed. The code is as follows:
yum install sendmail
By the way, the host name must be set in a domain name format, for example :jb51.net, otherwise it will take a long time to start up when you restart sendmail, otherwise you will have to wait a long time. The code is as follows:
hostname .net
Then check whether sendmail is running normally. The code is as follows:
service sendmail status
If it is not running, it can be started. Change status to start. Then, edit php.ini and create a phpinfo in the web environment, because I use lnmp.
vi /usr/local/php/etc/php.ini
and then search :;sendmail_path =, press i to edit, replace with:
sendmail_path = /usr/sbin/sendmail -t -i
The default of my system is:
sendmail_path = /usr/sbin/sendmail -t -i -f
This -f seems to disable the mail function. After removing -f The mail function returns to normal. Then, restart the PHP process, usually: service php restart. LNMP is: service php-fpm restart. Under Apache, it can be: service httpd restart
. Let me share with you a php script test code. The code is as follows:
<?php $send = mail('your Email @lisizhang.com', '邮件标题', '测试邮件内容,如果收到此邮件,表示mail函数成功启用!'); if($send){ echo 'true'; }else{ echo 'false'; } ?>
If the return result is false, it means that the email is sent. If it returns true, it means that the email is sent successfully.

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.
