First, let's take a quick look at what is php,php (hypertext preprocessor hypertext Preprocessor) and the Java language, PHP is also a high-level language, and does not run directly on the operating system. The Java runtime requires a virtual machine, and PHP runs the Zend engine. Unlike Java, Java is a compilation and parsing language, and PHP is just a parsing language. So, we can easily see from the nature of the language, Java before running through the compilation of A. class file, so the efficiency will be faster, PHP after writing a program to check the syntax through, you can run directly, so that development efficiency will be faster.

Last year, when I started to transfer php from Java, PHP's weak type effect attracted me, in Java we often encounter various types of conversion, or consider what type to store data, this strict programming is very limited to the efficiency of development, of course, this disadvantage is its advantages, More stringent type definitions, allowing Java to run faster. Then, I remember when I learned php+mysql, I was very surprised! Why is PHP's operation on the database so simple, am I wrong to write it? Because when I first learned Java, MySQL's various jar bags get spit blood. Real PHP development is very good, so many PHP programmers will make a joke: PHP is the best language in the world. In fact, not the other language is not good, but as programmers like the kind of automated, less artificial methods to develop and maintain programs.

The above are personal understanding, not necessarily correct, if not, I hope you help correct me.

Back to the point: install PHP, we talk about the installation is not in Windows repeatedly click on the next process, so it is too boring. What I want to say today is how to install PHP in Linux and understand PHP extensions.

in my last note, I prepared the Linux system and configured the network.  install PHP, and turn on FPM# Update Systemyum-y Update

Upgrade all packages, change software settings and system settings, and upgrade the system version kernel
