PHP is a server-side scripting language that is used to create web applications. The PHP stands for PHP: Hypertext Preprocessor. It was created by Rasmus Lerdorf and first released in 1995. It is influenced by C, C++, and Java language.
It is mainly used to create web applications where it works server-side. We can use it to fetch data, store data into the database, and can be used to write business logic for the application.
PHP is popular among web developers to create quick solutions with less effort. If a developer has knowledge of either C or Java then can easily understand and write code in PHP.
There are several PHP frameworks available to make PHP more productive. The PHP frameworks such as Laravel, Symphony, CakePHP, Yii, etc are very popular.
For more detail, you can refer to the official documentation here. https://www.php.net/docs.php
It is a server-side scripting language.
It is a client-side scripting language.
It is used to create dynamic web pages.
It is used to handle the client-side.
It is an object-oriented language.
It is a prototype-based language.
It was created by Rasmus Lerdorf in 1995.
It was created by Brendan Eich in 1995.
Its file extension is .php.
Its file extension is .js.
It supports integration with various libraries like mail API, database handling, etc.
It can be integrated with Jquery, AJAX, etc to make the UI more under control.
It cannot work client-side. It means it does not run on browsers.
It can work on the client-side and server-side both by using the nodeJS runtime environment.
It is secure since it executes on the server-side.
It is less secure.
It is faster than PHP.
Since PHP is easy to learn and write so writing a simple Hello World application does not require much code and effort. We can print “Hello World” by using a simple statement. PHP code requires a PHP tag to enclose the code so that compiler can treat it as PHP code. See the example below where we are printing a message to the browser and notice it is wrapped with a tag.
PHP code can be embedded into HTML code to create dynamic web pages. See, we created a simple “Hello World” application with HTML tags.
The following are some advantages of using PHP language.
PHP is an open-source Scripting language.
It is easy to learn.
It has a rich set of library functions
It supports a wide range of databases such as MySQL, Oracle, MongoDB, MariaDB, etc.
It is platform-independent, which means code written in PHP can execute on Windows, Linux, and even on Mac OS.
It is secure it executes on the server-side. It means code not available at the client-side on the browser.
It has a vast and worldwide developers community to support.
It is very effective for creating dynamic web applications on a budget.
It has numerous frameworks such as Laravel, Yii, CodeIgnitor, etc for fast web development.
It is easy to learn, code, and embed.
It takes less response time due to browser-side execution.
It supports all the major browsers such as Chrome, Internet Explorer, Safari, etc.
It has several frameworks such as NodeJS, AngularJS, ExpressJs, ReactJs, etc.
It is easy to debug and test at the client-side.
We can use PHP code either at the client-side or server-side. It means if we create a dynamic web page then we can add PHP with HTML code. If we just want to write business logic then no need to add with HTML, simply write code in PHP at the server-side.
See the example below where we created a simple “Hello World” application using PHP.
This approach is good when we are writing code for business logic at the server-side. Since at the server-side only PHP code is required to perform operations and communicate to the database. Here, no need to embed code into HTML since HTML does not work on the server so doing so makes no sense.
This approach is good only when we want to create dynamic web pages that contain some dynamic data carried by the PHP code from the server-side so we can embed that into an HTML page to make HTML on the fly.
This tag will read the code from the file and all done!
The following are some popular PHP frameworks that are highly in demand.
The following are the big applications and brands that use PHP.
Answer: PHP is one of the most popular server-side languages. According to a survey, PHP is used by almost 75% of all websites. So, thinking of such is not a good idea.
