PhP

PHP is a general-purpose scripting language for web development. It was first created in 1994 by Danish-Canadian programmer Rasmus Lerdorf. PHP reference implementations are now created in PHP groups.

1.What is PHP?

PHP started out as a small open-source project that grew as more and more people found how useful it was. Rasmus Lerdorf released the first version of PHP in 1994.

  • It is used to manage dynamic content, databases, session tracking, and to build an entire ecommerce site.
  • Integrates with several popular databases including MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server.
  • PHP runs very fast, especially when compiled as Apache modules on the Unix side. Once executed, the MySQL server executes even very complex queries involving massive result sets in record time.
  • PHP supports a number of major protocols such as POP3, IMAP and LDAP. PHP4 adds support for Java and distributed object architectures (COM and CORBA), enabling layered development for the first time.
  • PHP is tolerant: The PHP language is as tolerant as possible.
  • PHP Syntax is C-Like.

Characteristics of PHP

The practical nature of PHP is made possible by five important characteristics:

  • Simplicity
  • Efficiency
  • Security
  • Flexibility
  • Familiarity

Simplicity

(PHP: Hypertext Preprocessor) A very popular scripting language used to create dynamic web pages. Combining the syntax of C, Java and Perl, PHP code is embedded in an HTML page for server-side execution.

Efficiency

According to official PHP benchmarks, PHP 7 can execute twice as many requests per second compared to PHP 5.6. According to Kinsta's PHP performance tests, WordPress 5.0 can handle 3x more transactions than PHP 5.6. as well as Pantheon reported that PHP 7 improved by 64% compared to version 5.3.

Security

According to W3Techs' April 2019 data, 79% of websites are running PHP. These websites include Facebook, Yahoo, and Wikipedia. Because PHP is so popular, PHP security is essential and there are a lot of vulnerable PHP applications.

Flexibility

The flexibility of PHP configuration competes equally with the flexibility of your code. PHP can be used to build full server applications with all the capabilities of a shell user, or for simple server-side connections with little risk in a tightly controlled environment.

Familiarity

Let's take a look at some of PHP's unique features. Simple, friendly and easy to use. It is widely regarded as simple, familiar, and easy to learn because its syntax is similar to C or Pascal. Therefore, it is a very logical and well-formed general-purpose programming language.

2. Is php still used?

It's true that PHP fell from #5 in 2017 to #8 in 2020 on Stack Overflow's annual developer survey of Most Popular Programming Languages. Nevertheless, PHP continues to be used on nearly 80% of all websites on some major platforms like WordPress and Facebook.

3. Which program uses php?

It is used to manage dynamic content, databases, session tracking, and to build an entire ecommerce site. Integrates with several popular databases including MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server.
