What are the key Responsibilities of a PHP Developer?
As a PHP developer, you’ll have a range of responsibilities depending on the project you’re working on and the company you work for. Some of your responsibilities include:
1. Writing Code
As a developer, your primary task will be to develop clean, secure, and efficient PHP code. This comprises comprehending the application’s requirements and specifications, translating them into code, and verifying that the code provides the intended functionality. Developers must have expertise with Laravel or CodeIgniter and a sound understanding of object-oriented programming principles to design reusable and scalable code.
2. Testing and Debugging
A PHP Developer must be able to test and debug the code to verify that it satisfies the functional and technical requirements. Thus, developers should be comfortable using debugging tools and testing frameworks such as PHPUnit and troubleshooting difficulties. This includes finding and fixing issues, ensuring compatibility with different browsers and devices, and improving the program’s performance.
3. Collaborating With Cross-Functional Teams
A developer must work closely with project managers and other developers to ensure the apps are delivered on time and satisfy client expectations. This involves conveying project progress updates, participating in team meetings, and working on code reviews. You should be able to operate well in a team atmosphere and have excellent communication abilities.
4. Database Management
As a PHP developer making and maintaining databases for web applications will fall within your purview. This is part of creating database schemas, optimising query efficiency, and ensuring data security. Moreover, a developer should be familiar with SQL and able to develop effective queries to get and update data. He should also understand database management solutions like MySQL, MongoDB, or PostgreSQL.

6. Testing and quality assurance
As a PHP developer, your main job is to ensure that your code works as planned and meets all criteria. Detailed testing and quality assurance are needed to ensure that web apps are stable and bug-free. To guarantee that your code is of good quality and satisfies the project’s goals, you must create unit tests, run functional and integration testing, and do other quality assurance.
Must Ask Interview Questions While Hiring PHP Developer?
When hiring a PHP developer, assessing them is critical to verify they have the required abilities and expertise. Thus, here are some of the questions you can ask the developer while hiring them,
Q1. What distinguishes the PHP functions include() from require()?
The need() and include() methods in PHP include a file. The primary difference is that if the file cannot be found, need() will throw a fatal error and terminate the script, whereas include() will merely throw a warning and continue processing.
Q2. What distinguishes the PHP unset() from unlink()?
The unset() procedure destroys a variable, but the unlink() function deletes a file from the server.
Q3. Explain the difference between abstract classes and interfaces in PHP.
Abstract classes are non-instantiable classes with one or more abstract methods that must be executed by any class that extends the abstract class. Interfaces, nonetheless, establish a set of methods that every class implementing the interface must execute.
Q4. What is a session in PHP?
In PHP, a session is a method of storing information about a user across numerous pages or requests. The session data is saved on the server and is accessible and modifiable as needed.
Q5. How would you protect a PHP application against SQL injection attacks?
SQL injection attacks arise when user input is not adequately sanitized and is directly incorporated into SQL queries. You may avoid this by using prepared statements with parameterized queries. Prepared statements isolate the query from the user input, and the parameters are delivered to the database separately, preventing harmful SQL code from being run.
Q6. What is the difference between PHP sessions and cookies?
In a PHP application, sessions and cookies save data over several requests. The primary distinction is that sessions save data on the server, whereas cookies store data on the client.
Sessions are typically regarded as more secure because the data is not accessible to the client, although they might consume more resources. While cookies are easier to deploy and may be used for client-side functionality, such as remembering user preferences or the contents of a shopping cart.
Q7. How would you improve the performance of a PHP application?
There are various techniques to improve the speed of a PHP application, including employing a caching system, optimizing database queries, minimizing file inclusions, and using a content delivery network (CDN) to serve static assets. Performance can also be increased using a profiler to identify performance bottlenecks and speed up the code.
Q8. Differentiate between GET and POST requests in PHP?
The GET and POST methods are used in PHP applications to send data from the client to the server. The main difference is that GET requests contain the data in the URL, whereas POST requests transmit the data in the request body as form data or file uploads. Also, as the data is not accessible in the URL, POST requests are more secure.
Q9. What are PHP namespaces? How do they aid in the avoidance of name conflicts?
Namespaces are used to organize code and eliminate name problems. They enable you to determine a collection of classes, functions, and constants under a single name. Namespaces also allow you to use the same class name in several namespaces. You may determine a namespace in PHP using the namespace keyword and the name of the namespace.
Q10. Explain the difference between need and include in PHP.
Both need and include are used to add PHP files in another PHP file. The difference is that require produces a fatal error and terminates the script if the file being included is not found, whereas include generates a warning and continues script execution. In general, it is best to use require when including files that are critical to the script’s operation and include when adding files that aren’t.
Q11. What is the difference between an isset and an empty?
isset is a function that decides whether a variable is set or not null, whereas empty determines whether a variable is set. Consider an example of a variable with 0 or an empty string. In that case, isset returns true, whereas empty returns true only if the variable is set to an empty string or a value that estimates to false.
Q12. Differentiate between static and non-static methods in PHP?
Unlike non-static methods, which can only be used on a class instance, static methods can be called without creating an instance of the class. In contrast to non-static methods, which alter the state of the class instance, static methods are frequently used for utility operations that don’t need access to the class’s internal state.
Q13. What is the function of the PHP keyword “use”?
To import namespaces and classes into the current namespace or class, use the “use” keyword. It enables you to refer to a namespace or class by a shorter name, which can aid in avoiding naming conflicts. For example, if you have a class named “Database” in the “App/Models” namespace, you may use “use AppModelsDatabase” to import it into another class.
Q14. How can you prevent a user from visiting a specific page in PHP?
In PHP, you may stop users from visiting a specific page by validating their session data and redirecting them to another page if they are not permitted.
