PHP is a computer language that allows web developers to produce dynamic content interacting with databases. PHP is a programming language mostly used to create web-based software applications. This lesson will assist you in constructing your PHP foundation.
Why should you learn PHP?
PHP began as a small open source project that grew in popularity as more people realised its benefits. In 1994, Rasmus Lerdorf released the initial version of PHP.
PHP is a must-have skill for students and working professionals who want to become exceptional software engineers, especially if they work in the Web Development field. I’ll go through some of the main benefits of learning PHP:
“PHP: Hypertext Preprocessor” is a recursive abbreviation for “PHP: Hypertext Preprocessor.”
PHP is an HTML-enabled server-side programming language. It’s used to manage dynamic content, databases, and session monitoring and create full e-commerce websites.
MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server are just a few of the databases it supports.
PHP runs quickly, especially when built as an Apache module on the Unix side. Once launched, the MySQL server performs even the most sophisticated queries with large result sets in record time.
POP3, IMAP, and LDAP are just a few of the important protocols that PHP supports. PHP4 included support for Java and distributed object architectures (COM and CORBA), allowing for the first time n-tier programming.
PHP is forgiving: The PHP programming language makes every effort to be as compassionate as possible.
The syntax of PHP is similar to that of C.
PHP Characteristics
Five key traits enable PHP’s practical nature. −
Simplicity \sEfficiency
Security \sFlexibility
Familiarity
Using PHP, say Hello World.
I will offer you a simple traditional PHP Hello World programme to get you excited about PHP. You can try it out using the Demo link.

PHP’s Applications
As previously said, PHP is one of the most extensively used languages on the Internet. I’ll mention a handful of them below:
PHP performs system functions, such as creating, opening, reading, writing, and closing files on a system.
PHP can handle forms, which means it can gather data from files, save data to a file, send data via email, and return data to the user.
PHP allows you to add, delete, and alter elements in your database.
Cookies variables may be accessed, and cookies can be set.
You may limit visitors’ access to certain website sections using PHP.
It can encrypt data.
Audience
