This article mainly introduces the relevant knowledge of the language features of php, the content is detailed and easy to understand, the operation is simple and fast, and it has a certain reference value. I believe you will gain something after reading this php language features. Let's take a look.

PHP language features: 1, PHP language can run with a variety of operating systems; 2, PHP supports a variety of mainstream and non-mainstream databases; 3, web back-end CGI programs written by PHP can be easily ported to different operating systems.

This article operating environment: Windows10 system, PHP7.1 version, Dell G3 computer.

What are the language features of php

1. Cross-platform features:

PHP language can run on Linux, FreeBSD, OpenBSD, Windows and other operating systems.

2. Database support:

PHP supports a variety of mainstream and non-mainstream databases

3. Security:

Encryption support, PHP4 implements complete encryption, these encryption functions are a complete mycrypt library, and PHP4.0 supports hash functions. Blowfish,TripleDES,MD5, and SHA1 are some of the encryption algorithms that can be used. Use PHP language to run Linux, FreeBSD, OpenBSD, Solaris?Unix operating systems, do not need to install any antivirus software and patches, safe and reliable.

4. Scalability:

Expanded API module: PHP4.0 provides extended PHP interface module for extended API and module. Jinan website construction believes that it is significantly faster than the old API version. Most of the existing and most commonly used interfaces of PHP and modules are converted to interfaces that use this extension; in addition, PHP is open source software and its source code is completely open, so it is very easy for any programmer to extend additional functions for PHP so that PHP has a good space for development and expansibility.

5. Fast execution:

PHP is a powerful CGI scripting language, the syntax is a mixture of C, Java, Perl and PHP-style new syntax, the execution of web pages is faster than CGI, Perl and ASP, which is its first prominent feature; in terms of memory, PHP4.0 can use memory more effectively. It results in less memory consumption, which is mainly due to the implementation of reference counting technology.

6. Portability:

The Web back-end CGI program written by PHP can be easily ported to different operating systems. For example, a website that starts with Linux can quickly move the entire system to a SUN workstation when the system load is too high, without having to recompile the CGI program. Faced with the rapid development of Internet, this is the best choice for long-term planning.

7. Functional comprehensiveness:

PHP includes graphics processing, encoding and decoding, compressed file processing, XML parsing, identity authentication supporting HTTP, Cookie, POP3, SNMP and so on. You can use PHP to connect to most databases, including Oracle,MS-Access,Mysql. From the object-oriented design, structured features, database processing, network interface applications, security coding mechanism and so on, PHP covers almost all the functions of all websites.

8. Scalability:

Traditionally, the interaction of web pages is realized through CGI. The scalability of the CGI program is not ideal because it opens a separate process for each running CGI program. The solution is to compile the interpreter of the language commonly used to write CGI programs into a web server (such as mod_perl,JSP), and PHP can be installed in this way. Embedded PHP can be more scalable.
