HHVM,没毛用?!
在虚拟机上面装了LNMP环境,由于最近一直在关注性能问题所以就试着把HHVM也装上了。因为整个机器是刚刚装好的,装HHVM之前我也没测试一下原生状态下PHP脚本的性能(悔不当初啊!)。
一切妥当以后我开始测试,分别在命令行下执行了一遍
php -f some.php
hhvm -f some.php
执行结果伯仲之间,我就郁闷了。
疑问:
1.装的HHVM没有成功?(但是HHVM服务已经启动,网页访问正常。用hhvm执行PHP脚本正常)
2.HHVM装好以后就不能和原生的PHP分离了?
最近有没有用HHVM的大牛,进来共同探讨一屉?

亲,HHVM用于处理复杂业务逻辑会得到性能极大提升。
您做测试,分别测试echo "hello world";这样的简单业务逻辑, 在怎么测试都没什么毛用。
还有,请测试多并发(高压力)下,原生PHP和HHVM的性能差异。
性能提升不了多少。
我在typecho程序上测试过,打开首页 同一台服务器 php5-fpm 需要 150ms hhvm之需要30ms
但是hhvm占用的内存高很多

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

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 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.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

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.
