PHP: a general open source scripting language. Grammar absorbs the characteristics of C language, Java and Perl, which is convenient for learning and widely used. It is mainly suitable for the field of Web development. PHP's unique syntax is a mix of C, Java, Perl, and PHP's own syntax. It can execute dynamic web pages faster than CGI or Perl. Compared with other programming languages, PHP embeds the program into HTML (an application under the standard general markup language) document to execute the dynamic page made by PHP, which is much more efficient than the CGI that completely generates HTML markup. PHP can also execute compiled code, which can encrypt and optimize the code to run, making the code run faster.

In ancient times: the web page used HTML language and hypertext markup language to display the text and pictures to the web end according to the HTML syntax format. But HTML is a static page, and then there is a JavaScript that the scripting language is embedded in the source code of HTML pages. Users download it from the browser and execute it locally, so the execution speed is related to the local host.

Then there was a PHP: PHP is also a scripting language, but it runs on the server side, and the dynamics and interaction on the web page depend on the computing power of the server.

Interpretive language: the same interpreter performs various operations according to the script

Apache: web server software (WEB server refers to website server.), Apache is used to build websites, just like IIS on windows platform, for example, your machine is equipped with linux,unix or windows NT/2000. Wait for the operating system and then you install Apache, your machine can become a server, if you apply for a fixed ip in isp (internet service provider), then others can browse your website through this ip.

Web server: refers to the website server. To put it simply. It is the server used to put the data of the website. All the words on a website. Pictures and so on are collectively referred to as data. These data do not appear in the network out of thin air. Instead, there is a server supporting it in the background. When the user visits the website. In fact, a request was sent to the server through the network. The server then feeds back the page requested by the user to the user. Only at this time can users see the exquisite interface of the site. And the Web is the server that provides data services in the background.

Refers to the website server, refers to the program that resides in a certain type of computer on the Internet (passive server side), can provide documents to browsers and other Web clients, can also place website files for the world to browse, and can place data files for the world to download. Currently, the three most mainstream Web servers are Apache Nginx IIS.
