About with this essential post on Web Development, you will discover what is PHP and what it can perform.
Internet was born in 1994 as soon as it came in the history of W3C, owing to which today we use it for any sort of information. Tim Berners-Lee who is its founder done a lot of work towards the creation of web layers. The markup language through which a web page is produced is thanks to them. But why is it important to learn all this "PHP"?
Initially, markup language (HTML, XML, etc.) was used to construct web pages. You must have observed that previous websites were very simple. You used to see simply text on them. That is to say, they did not appear like today's websites. As the number of Internet users rose, the design of online sites was also swiftly improved.
As the number of Internet users rose, the design of online sites was also quickly changed. CSS was developed in 1998, with which designing of any web page may be done. The layout, font color showed on a web page are all made with CSS. To improve such websites, several coding languages such as programming language, general-purpose programming language, and scripting language were created.
PHP is a sort of scripting language. Which is used in web development. If you want knowledge on how to build a website, then this post is very important for you. So let us know what is PHP and why PHP is used to grasp PHP more carefully.
What is PHP
The full definition of PHP is : Hypertext Preprocessor. It is a server-side scripting language developed for web development. PHP is also used for general-purpose programming language.
History of PHP
PHP was invented in 1994 by Rasmus Lerdorf. Lerdorf first designed it to track your online resume. Which he dubbed Personal Home Page Tool (PHP) (PHP). Due to Rasmus's huge thinking and more functionality, he started rewriting the PHP tool and a new PHP model was built. The database interface of this new model was more efficient.
Due to Rasmus's huge thinking and additional features, he started rewriting the PHP tool and a new PHP model was built. The database interaction of this new model was more efficient. Through this, a framework was supplied to the user. With the help of which users may create basic dynamic web apps such as guestbooks.
In June 1995, Rasmus released the source code for PHP tools, now developers could improve on dynamic web applications developed with the aid of this code as well as fix problems in the code. In a manner, the developer was allowed that he may fit it anywhere he wants. After this numerous improvements were done in PHP. Many programming languages were also developed.
After this, many improvements were done in PHP, several programming languages were also developed. PHP 3.0 was published in 1997 which was the first version of PHP. It was much more capable than the previous version. After its introduction, many limited applications of PHP were ended, and then its name was changed from PHP home page to PHP Hypertext Preprocessor.
Even after this, developments in PHP continued, following PHP 3.0, PHP 4.0 and now PHP 5.0 has been published. Modern PHP is so competent that multitasking websites like Facebook, Amazon, WordPress have been created using it.
What can PHP do?
PHP is a server-side programming language. By which you may build a Dynamic page. You can open, read, write, remove and close files on a server. PHP may also add, delete, and change data in your database. With PHP you can simply embed Html.
All CGI scripts can be done using PHP. A CGI program is software intended to take and return data according to the CGI definition. With the aid of this, you may gather Form data. Can produce dynamic page content and send and receive cookies.
But there are three primary places where PHP script is used:
Server Side Scripting — This is a method used in web development. In which the employing script is included in the webserver. Which creates a customized answer to the request of every user of the website. Server-side scripting is the most traditional and major target sector for PHP.
Writing Desktop Application - PHP is probably not a good language to develop a desktop application with a graphical user interface. But if you know PHP well and want to use some advanced PHP features in your client-side application then you may use PHP GTK.
Command Line Scripting - You may write a PHP script to run it without any server or browser. You simply need a PHP parser to use it this way. These scripts are also useful for simple text processing jobs.
How does PHP work?
PHP software works with web servers. This program provides web pages to a user. Think of it like this, when you write the URL of a website in the search box of your web browser, you are sending a message to the web server by entering that URL that the webserver should show that website in your browser.
As soon as the message is read, the webserver sends the HTML file of that website to your browser. Your browser scans the HTML file and displays the web page of the website in front of you. Now there will be a query in your mind that what is the role of PHP here. Here PHP works as an interface.
The interface means that it converts the request provided to the server into machine language. Whenever a request for a file arrives in the server, the PHP interpreter converts that code and accesses it in the database and from there picks up the file and delivers it to the server. After which the server sends the file to the user.
