With the large availability of PHP developers, businesses can use PHP programming to create their development. 

What is PHP?

PHP stands for PHP hypertext processor and it is an open-source server-side scripting language that is commonly used to develop static or dynamic and interactive websites. Programmers can easily embed PHP with HTML files. PHP continues to gain popularity after some years, even with newer choices like Python or JavaScript. 

A PHP feature that distinguishes is that the code execution occurs on the server instead of the client side of the internet that a user can view. PHP language code creates HTML, which is subsequently sent to the clients. This makes the language very safe and guarantees that users cannot see what is happening behind the screen.

PHP language as well as being embedded into HTML, coders can also combine it with web template systems, web content management systems, and web frameworks and libraries.

What is PHP Used for?

PHP language is ideal for creating complex web pages. This scripting language can collect data, generate dynamic page content, enhance web pages, create usernames and passwords, and send & receive cookies. Some primary forms of websites use PHP in their code-

• Secure websites used for payment i.e. PayPal
• Email web hosting platform i.e. Gmail
• Content Management System i.e. WordPress
• E-commerce websites with heavy amounts of traffic i.e. Amazon
• Database Management and social media platforms i.e. Wikipedia or Facebook

Why use PHP?

PHP encourages programmers to embrace rapid application development which helps them save time, avoid code repetition and create stable products as swiftly as possible without PHP, there would be a lot of code repetition and developers would have to set up every database connection from the start. 

PHP framework and libraries include pre-fill modules for accomplishing time-consuming coding activities. This implies that the developers will devote more time and effort to creating actual applications rather than developing the groundwork for every project. 

PHP Syntax

 

All syntax starts with <?php and ends with ?>. Each syntax line is closed out using a (;).  Various components go into PHP syntax that is used to code the server side of a website.

Variables

Variables are case-sensitive and start with the $ sign followed by the variable's name. There is various type of variables:

• String - It is a sequence of characters, like “hello World!”. A string can be any text enclosed in quotation marks. You can also use single or double marks.
• Integers- These are whole numbers without a decimal point between -5, 1, 5, 8,97, and 3043.
• Float- A floating point number is a decimal or exponential number. 
• Array- An array stores multiple values in one single variable. 
• Null- It is a peculiar data type with just one possible value. A variable of data type NULL has no assigned value. 
• Boolean- It represents two possible states: True or false.

When assigning a text value to a variable use quotation marks around the name. Since variables are case-sensitive, the variables are two different variables. 

Constant

In the language, this constant is also case-sensitive and always begins with an uppercase letter or underscore, not an alphabetical letter. Constants are written using the () function. It is different from variables because constants are not defined by a simple assignment, as they are written and accessed anywhere using define. Once they are specified they cannot be changed or undefined.

How does PHP Work?

PHP is an interpreted and versatile language. This implies that PHP will understand your web application code for each request. Since PHP is a server-side programming language the complete processing takes place on the server. A PHP interpreter is also installed on the server to check for PHP files. The prerequisites for web browser and internet connection on the user end. 

Here are some process of how does PHP work- 

• The users open the browsers and request the webpages
• The server looks for the .php file corresponding to the request
• Once located the files are sent to the PHP interpreter which searches the databases for the desired data.
• The interpreter returns the desired data output in the form of HTML websites.
• The web server receives the HTML file
• The web server sends the webpages to the browsers.
