PHP Hypertext Preprocessor (PHP) is an programming language that allows web developers to develop dynamic content that communicates with databases. PHP is used to develop web-based software applications. This guide will help you create your foundation using PHP.
What is PHP Programming?
The word PHP is an abbreviation for PHP Hypertext Preprocessor. PHP is a server-side scripting programming language created especially for development of web pages. PHP is able to be integrated into HTML files, and HTML codes can be written in the PHP file. What differentiates PHP from a language that is client-side similar to HTML is that PHP code is executed by the server, while HTML codes are rendered directly in the browser.
PHP was developed by Rasmus Lerdorf in 1994, but it was first released on the market in 1995. PHP 7.4.0 was the most current version of PHP which was launched on the 28th of November. A few important aspects that need to be noted regarding PHP are:
Print Hello World using PHP
To give you some excitement over PHP I’m going to offer a simple PHP Hello World program, It is possible to test it out by clicking on the link.
Syntax of PHP
<span class=’wordai-block rewrite-block’ data-id=’11’>
Hello World</span>
Why to Learn PHP?
PHP began as an open source project which grew with time as more and better people realized how valuable it could be. Rasmus Lerdorf launched PHP’s first release PHP in the year 1994.
PHP is an absolute must for professionals and students to develop into a skilled Software Engineer, especially if they work in the Web Development Domain. I’ll list a few important benefits of studying PHP. The term PHP refers to a repeating acronym that means “PHP: Hypertext Preprocessor”.
It’s compatible with several of the most well-known databases, including MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server.
PHP is surprisingly fast in its execution, particularly when it is compiled in the form of an Apache module on the Unix side. MySQL is a MySQL server when it is started runs extremely complicated queries that produce huge results sets in record time.
PHP supports a wide range of the most popular protocols, including POP3, IMAP, and LDAP. PHP4 introduced the ability to support Java and distributed object structures (COM as well as CORBA) which makes an n-tier design possible in the very first instance.
Characteristics of PHP Programming
Five key features make PHP’s practical nature possible.
- Simplicity
- Efficiency
- Security
- Flexibility
- Familiarity
Applications of PHP
As we’ve mentioned, PHP is one of the most used languages across the internet. I’ll list a few of them below. PHP executes system-wide functions, i.e. from the files in a system it can open, create it, read, write or close the files.
PHP is able to handle the use of forms i.e. collect information through files. It can also save information into an email, and then you can transmit information, and then return the data back to users.
You can add, remove, or modify the database’s elements by using PHP. Access cookie variables and set cookies. Utilizing PHP it is possible to limit users from accessing certain pages on your site. It is able to encrypt data.
Audience
The PHP instructional video is designed to help PHP programmer who are ignorant of PHP concepts, but have a basic knowledge of programming in computers.
Prerequisites
If you want to learn you must have an understanding of basic computer programming, Internet, Database, and MySQL.
The word PHP is an abbreviation of PHP Hypertext Preprocessor. PHP is a server-side scripting programming language created especially for development of web pages. PHP is able to be integrated into HTML files. HTML codes can be written in the PHP file. The main difference between PHP from a language that is client-side similar to HTML is that PHP code is executed by the server, whereas HTML codes are rendered directly in the browser.
First Program of PHP
Example: It’s an easy PHP program that prints “Hello world!” message on the screen.
“echo” is a print-command/
Echo “Hello world! “;?>
Output:
Hey world!
What is the reason we should need to learn PHP Programming?
PHP is an open source, interpreted and object-oriented scripting language which can be used on the server side. PHP is well-suited to web development. It is therefore used to create web-based application.
PHP is among the most widely-used open-source general-purpose scripting languages used for Web Development. Beyond that let’s look at the reasons why we should be learning the language.
It is easy to learn: PHP is easier to learn for people who have encountered any new programming language.
Free of Cost: As PHP is an open source language, developers are permitted to use its components as well as all methods at no cost.
Flexible: As PHP is an open source language that is dynamically typed so there aren’t rigid rules about how to create features with PHP. It is a language that is flexible.
Supports almost all databases: PHP can support all the commonly used databases, which include MySQL, ODBC, SQLite and more.
Open Source: PHP source code and the software are available for free on the internet. You can create all versions of PHP depending on your needs without costs. All of its components are available for download and use.
Secure: PHP provides us a secure platform for creating websites since it comes with various levels of security.
A huge community support: PHP is loved and utilized by a large number of developers who are eager sharing their knowledge with other members of the community that want to know more about PHP.
Performance: PHP scripts run much faster than scripts that have been written using other programming languages, such for JSP or ASP. PHP utilizes the memory of its own, which means the load on servers and loading time are automatically decreased, which results in more speedy processing and improved performance.
