What are the language features of php

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

The operating environment of this article: Windows 10 system, PHP version 7.1, Dell G3 computer.

What are the language features of php

1. Cross-platform features:

PHP language can run on Linux, FreeBSD, OpenBSD, Windows, etc. Multiple 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 also some of the encryption algorithms that can be used. Use PHP language to run Linux, FreeBSD, OpenBSD, Solaris? Unix operating system, no need to install any anti-virus software and patches, safe and reliable.

4. Scalability:

Expanded API and modules: PHP4.0 provides extended PHP interface modules for extended APIs and modules. 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 have been converted to interfaces that use this extension; in addition, PHP is open source software, and its source code is completely open. It is very easy for any programmer to extend additional functions for PHP, making PHP have a good Development space and scalability.

5. Fast execution speed:

PHP is a powerful CGI scripting language with a syntax that mixes C, Java, Perl and PHP With its new syntax, executing web pages is faster than CGI, Perl and ASP, which is its first outstanding feature; in terms of memory, PHP4.0 can use memory more efficiently, resulting in less memory consumption. Mainly due to the implementation of reference counting technology.

6. Portability:

Web back-end CGI programs written in PHP can be easily transplanted to different operating systems. For example, if a website is built on Linux first, when the system load is too high, the entire system can be quickly moved to a SUN workstation without recompiling the CGI program. Facing the rapid development of the 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, HTTP authentication, Cookie, POP3, SNMP etc. PHP can be used to connect to most databases including Oracle, MS-Access, and Mysql. From object-based design, structured features, database processing, network interface applications, secure coding mechanisms, etc., PHP covers almost all functions of all websites.

8. Scalability:

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