WHAT IS PHP?
PHP is a highly popular scripting language that is HTML-embedded. With PHP, a developer can create dynamic and interactive websites and web pages as well as a programming language. It supports Netscapes, Apaches Microsoft IIS, and so on. PHP works on Windows, Linux, UNIX and Mac OS. PHP has many outstanding features. Some of them include:
Open Source: PHP is open-source. Open source means that it can be used and modified by anyone. A developer can distribute it to anyone for any purpose. Web developers and web programmers can access PHP for free. PHP is distributed under a license that grants permissions of modification and redistribution to all. As such, open-source also means that developers can easily access PHP to learn how to use it.
User-Friendly: PHP is user-friendly. It is simple to understand and easier to use than most other scripting languages. It also works faster than other languages. With PHP, it is also possible to create websites that are highly user-friendly and that cater to the various needs of the customers. A website or web application developed using PHP frameworks can be optimized, modified, and updated as per the requirements. A developer can maintain all by himself a website that he has created.
Independent Platform: It is possible to run PHP on various platforms such as Windows, Linux, UNIX, Mac OS, and others, and therefore, it is called a platform-independent language. It depends on a web server to execute its code and is independent of the operating system that is being used. A PHP application can be developed in a particular operating system and then implemented in other operating systems very quickly. And all of this is possible free of cost. However, PHP needs a PHP interpreter such as XAMPP and LAMPP to run on any system.
Error Generation and Reporting: PHP can generate errors as and when they arise and report them quickly. With PHP, it is to locate the mistakes and fix them. This is why it is suitable for both beginners as well as proficient web developers. To generate syntax errors, a developer needs to enable an error display feature in the php.ini. These error messages are turned off by default so that a customer does not see them. PhpEd is a helpful editor that checks for errors when the codes are typed. PHP also has a debugger that provides detailed information about different errors.
Web Hosting: All web hosts support PHP. You can host your PHP website using CloudWays. Hosting your website means that the user can access the website by using the domain name of your website. This task is effortless when you create your website using PHP.
BENEFITS OF PHP:
PHP is open-source and easily accessible.
It supports multiple databases, such as IIS and MySQL.
It is highly compatible and can run on any device.

WHAT IS PHP WEB DEVELOPMENT?
PHP is a widely used language for web development that includes web designing, writing codes, web content development, and so on. Web designing consists of client-side or front-end coding, server-side or back-end coding and database technology, all of which can be done using PHP alone.
HOW TO LEARN PHP WEB DEVELOPMENT?
These days there are various sites and online resources from where you can learn PHP very quickly from the comfort of your home. You need not have any prior knowledge to learn PHP from scratch. To have a good understanding of PHP web development, you need to learn some of the following things:
Writing a Program in PHP: Writing code in PHP is simple. You can learn to write codes in no time. If you have some experience in working with other programming languages, this task should be a breeze.
Installing XAMPP and NetBeans in PHP: Installing XAMPP and NetBeans is easy. You can look them up online and download them for free.
PHP Data Types, Operators, and Variables: Data type refers to the classification of data based on attributes. PHP supports data types like integer, floating-point number, character string, Boolean. It also has a global variable and a local variable. By variable, we mean a memory location where data is stored at run time. Variables are used to separate data from the program algorithms. PHP has several operators like arithmetic operators, assignment operators, comparison operators, and so on. Arithmetic operators help to perform arithmetic operations on numeric data. Assignment operations help to assign variable values, and compassion operators help to compare values and data types.
Arrays: An array refers to a special variable that holds several variables at a time. PHP has indexed arrays, associative arrays, and multidimensional arrays.
PHP Loop and Control Structures: Control structure refers to a block of code which determines the path of execution of a program. This depends on the value of the condition that is set. If...then...else is one of the simplest control structures in PHP.
Creating PHP Strings: It is easy to create strings in PHP. You must know how to store a string in a function and a variable.
PHP Forms: Forms are essential to any website to receive user input and even feedback. Websites usually have a login or registration form. HTML is used to create a webpage form, and PHP acts as the medium for transferring the values from the webpage to the server and processing them. You must know the process of using HTML for creating forms.
Cookies and Sessions in PHP: Cookies are used to track application status using small files that are stored on the user's device. Sessions have several uses such as securely storing user id so that cyber attackers can not retrieve it.
File Processing and Error Handing: Sometimes, there is an unexpected program result that the program cannot handle on its own. Such results need to be avoided to ensure that the user is fully satisfied and to improve application security. PHP displays error messages when they occur. There are several ways to handle errors in PHP, such as die statements, custom error handlers, PHP error reporting, and so on.
Accessing Database: You need to know how to access the database in PHP. You also need to know how to use PHP to connect to MySQL's database.

HOW TO DEVELOP A PHP WEB APPLICATION?
A PHP developer develops a PHP website or web application. He or she works on the server-side of the website and builds back-end components. Some of the responsibilities of a PHP developer include integrating front-end elements with back-end elements, building PHP modules that are efficient and reusable, dealing with performance issues and architectural problems, integrating data storage solutions and so on.
Developing a PHP web application is quite easy. But first, you must have some basic knowledge of PHP, HTML, CSS, MySQL, and JQuery. These are essential to customizing and application. Once you have learned these languages, the steps are quite simple. To create a PHP website make all your file extensions .php instead of .html. Insert codes as applicable and insert <?php ?> tags. Add more functions as you go to make the application more interactive.
Steps to creating a PHP application:
Ensure that you have installed PHP and MySQL on your system: Installing PHP and MySQL is the first step to developing a PHP web application. To install them must first install a server on which both PHP and MySQL can run. Servers like XAMPP are widely recommended for this. It installs both PHP and MySQL. You can also manually install PHP and MySQL. A simple Google search will provide you with links to download them, and you can download and install them in no time.
Create a database for your application: Creating and naming a database is very easy. Suppose you want to create a website for an institute, you can create an Institute Database with tables like "students", "teachers", "parents" and "staff". You can create a database like "institute_db".
Create the SQL script for the database and import your SQL file in that database: Create an SQL script and save it as "institute_db.sql". Then go to http://localhost/phpmyadmin. Create a database named "institute_db". Import the SQL file in the database you created.
Now download a template once the database is set up: To create a template, you need to download it first. Suppose you want to use AdminLTE Template for your website. You need to download the template to use it. You can also clone AdminLTE and then unzip AdminLTE folder.
Create a layout page for the application and test it: Creating a layout page for the application is essential. Create a new file called master.php. This should be at the root folder. Once you have created a layout page load the contents of all the other pages that you have created into this page. Test it to ensure that it is functioning as expected.
Now you have to perform CRUD operations using PHP and MySQL: CRUD stands for Create, Read, Update, and Delete. At the base of your project directly create an "api" folder. Then create three new folders "config", "objects", "students" inside the API folder to keep all the Student API inside the "students" folder. To perform CRUD operations create a file inside the folder "students" called "create.php" for creating a new student, for reading records create "read.php", for updating create "update.php" and for deleting create "delete.php". To get the record of a single student create a file "read_single.php".
Create UI: You have already created a master.php as the layout page. You have also created a "student" folder at the root. Now create a page that will display all the data relating to students in a table using the template you had previously set up. Finally, connect the API and the UI.
HIRING PHP DEVELOPERS
There are several things you need to consider while hiring a PHP developer. Here are some of them:
The Kind of PHP Developer Suitable for Your Enterprise:
PHP developers are generally categorised into beginner, intermediate, and proficient. A beginner level developer has all the skills and qualifications that a PHP developer requires but he or she might lack sufficient work experience. An intermediate level PHP developer has more experience than beginners, but they are not as qualified as proficient level developers. However, while choosing a developer, you must keep in mind your budget on the project and the business expenses. A lower level PHP developer will be considerably cheaper than a proficient one.
Full-time or Freelancer:
If you need a developer for a long term project, you should hire a full-time developer. Otherwise, you should opt for a freelancer. A full-time developer is likely to be highly dedicated to your enterprise while a freelancer will do the work at the much-reduced cost. Hiring a freelancer will help you reduce your business expenses.
Which Hiring Source to Select?
When hiring a PHP developer, always choose the right source. Ensure that the profile of the candidate is verified. Well-known websites are likely to have experienced candidates with verified profiles.
Creating a Target Profile:
Always create a target profile to specify all your requirements in a candidate you desire to hire. Not all candidates will suit all your needs, and this will help you narrow down the list of applications.
Screening and Interview:
A proper screening process is essential in determining the right candidate for the job. You may prepare a set of questionnaires as part of the screening process. After the first round of screening always call the selected candidates for an interview. You can conduct more than one meeting if you are unsure about the best candidate. Preparing the questions from beforehand helps to address the right kind of problems.
Choosing a candidate with some work experience lets you know the kind of work he or she has done. It also gives you an idea about the variety of projects the candidate is capable of doing. You will be able to determine whether he or she is suitable for your enterprise.
Terms and Conditions:
It is better to discuss the terms and conditions with the candidate before hiring. Informing the candidate about his or her roles and responsibilities in the position, and the salary prevents confusion.

PHP DEVELOPER INTERVIEW QUESTIONS.
What are the various uses of PHP?
PHP has many uses. It can create, read, and write files. With PHP elements within a database can be modified. Cookies variables can be accessed. It is also possible to encrypt data using PHP.
What do we mean by "escaping to PHP"?
"Escaping to PHP" refers to the mechanism by which PHP codes stand out among other elements in a page. It reduces the ambiguity in quotes used in the string.
How do you connect to a URL in the PHP framework?
PHP includes a library called cURL or client URL which allows the user to connect to a URL. One can retrieve information from it such as it's HTML content, it's HTTP headers and so on.
Why do we use sessions and cookies in PHP?
A session is a global variable stored on the server. Each course has a unique id that is required to retrieve values that are stored. While cookies store small amounts of data, it is possible to save more significant amounts of data in sessions. Closing the browser erases the values of the course by default.
What do we mean by the scope of variables?
The scope of variables refers to the context which defines the variables. All PHP variables generally have a single range.
What do you know about Memcache? Can you share a single instance of Memcache between several PHP projects?
Memcache refers to a memory storage space run on several servers. One can share a single instance of Memcache between multiple PHP projects. Two different Memcache processes can also be run on the same host independently.
What are Echo and print?
Echo and print are used to print the output in the browser. The Echo is more efficient than the print method, but it does not return any value after printing the output. The print method, on the other hand, is slower than the Echo because after generating the result, it returns a Boolean value.
What is type casting and type juggling?
Typecasting refers to the way PHP assigns a particular data type to any variable. PHP, however, does not support datatype in case of variable declaration. Once a value is assigned, the nature of the variable is automatically changed and is called type juggling.
What are include() and require ()?
Include() and require() are used to add PHP script from one file to another. When we use an include() function, it shows an error message and continues to execute the script in case of any error. But for require(), the service is used to display an error message and stops running the text after that.
