PHP programming language -About PHP

PHP started out as a small open source project that evolved as more and more people found out how useful it was. Rasmus Lerdorf unleashed the first version of PHP way back in 1994. PHP is open source programing language. We can use php for multi purpose for example frameworks, website, packages and others. Many website and frameworks are developed on PHP such as WordPress, Codeigniter, Laravel and related others. If you want to develop a large scalable website so you can use PHP. PHP is a general-purpose scripting language that is used in creating Web pages and can be embedded in HTML code. (PHP stands for "Hypertext Preprocessor," even though the acronym doesn't match up exactly.) PHP is an open-source program, which means it's available for free on the Web. PHP can be used for a lot of different things, and is one of the most powerful scripting languages available on the web. Not to mention it's extremely cheap and widely used. However, one thing that PHP is lacking, and in fact most scripting languages are, is a way to update pages in real-time, without having to reload a page or submit a form. PHP can also be used across many platforms, such as Linux, many variations of the Unix system, Mac OS X, and Microsoft Windows. PHP is a complete programming language and can be used for functions such as server-side scripting (using a web server to fulfill a user's request by running a script directly on the webserver to generate dynamic HTML pages) or writing desktop applications. However, PHP's true strength lies in its ability to access databases. PHP can access more than 20 different databases (including MySQL) and can manipulate the information within those databases based on input from an online user. PHP can also be used to output images, PDF files, and even Flash movies from your website.

• PHP is a recursive acronym for "PHP: Hypertext Preprocessor".
• PHP is a server side scripting language that is embedded in HTML. It is used to manage. dynamic content, databases, session tracking, even build entire e-commerce sites.
• It is integrated with a number of popular databases, including MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server.
•  PHP is forgiving: PHP language tries to be as forgiving as possible.
•  PHP Syntax is C-Like.

 

First know about PHP:-

PHP is a server side scripting language that is used to develop Static websites or Dynamic websites or Web applications. PHP stands for Hypertext Pre-processor that earlier stood for Personal Home Pages PHP scripts can only be interpreted on a server that has PHP installed.The client computers accessing the PHP scripts require a web browser only.A PHP file contains PHP tags and ends with the extension ".php".A PHP file can also contain tags such as HTML and client side scripts such as JavaScript.

PHP:

Hypertext Preprocessor is a language designed for web development specifically back-end web development which handles server requests/server-side scripting. You can even output HTML code with it.

uses:-

1.PHP is open source and free.

2.Short learning compared to other languages such as JSP, ASP etc.

3.Most web hosting servers support PHP by default unlike other languages such as ASP This makes PHP a cost effective choice.

4.PHP is regular updated to latest technology trends.

5.Other benefit that you get with PHP is that it is a server side scripting language this means you only need to install it on the server and client computers requesting for resources from the server do not need to have PHP installed only a web browser would be enough.

6.PHP has in built support for working hand in hand with MySQL this doesn’t mean you can’t use PHP with other database management systems. You can still use PHP with Oracle MS SQL Server etc PHP is cross platform this means you can deploy your application on a number of different operating systems such as windows, Linux, Mac OS etc.

Advantages of PHP-

• All the PHP-based applications can run on various types of platforms.PHP is supported by the majority of Operating Systems, some of which include Solaris, UNIX, Windows, and Linux. The mentioned platforms can be used to write codes in PHP and also view web pages or run the PHP based applications. PHP easily interfaces with MySQL and Apache both. Effortless integration of PHP can be done with various other technologies like Java and there is no requirement of re-development. Therefore, saving both time and money, giving it an important advantage
• It can be used for written scripts that spawn sub processes to handle a large mailing list system and coordinate with the master process via process control functions
• A programming language like PHP is widely used on the internet and needs to connect to the database very often. Therefore, having a feature that could help PHP to connect to the database easily is mandatory. Several websites such as eCommerce websites require a good database management system.
• PHP has a built-in module that helps it in connecting with the database easily. Therefore, PHP has a great demand in the field of web development where a data-driven website needs to be developed. PHP significantly reduces the time needed in developing the web application that needs an efficient database management system.
• PHP is widely used because it is easy to use. In contrast with other programming languages that are complex, PHP is simple, fluent, clean, and organized, hence it is a boon for the new users. PHP has a well-organized syntax which is logical at the same time. PHP does not require any intensive studying or manual to use it.
