The article discusses about some of the technical interview questions, which are usually asked if you are appearing for the PHP jobs. Read on to explore!
Websites and embedded scripts form the base of the IT industry. The introduction of various server-side scripting language designed for web development, and general-purpose programming languages has contributed largely for the growth of the IT domain. Such languages are the wonderful source codes that are also being used in a number of social networking sites such as Twitter, Facebook, Yahoo, and others. Both government and non-government bodies are using this program globally to come up with the best solutions, while ensuring reduced costs and high quality.
A number of IT professionals opt for the SAP and Hypertext Preprocessor (PHP) training programs, as they offer an excellent platform to ensure great career prospects, which include better job positions and increased salary packages. However, to get into such result oriented computer programming professions, it is pretty tough to crack the interview processes.
Apart from the common questions asked in any interview, which include strengths and weaknesses, the interviewer may ask that why you want to work here, and other more detailed and technical questions related to your profession. Please note that questions vary, depending on the software programs and languages for which you are appearing in an interview (PHP, C +, Ruby, Java, among others).
Most of the questions, which are asked for the PHP jobs interviews, are mostly technical, which include; how to solve a problem using a particular computer language and also to discover the logic you apply! Some companies even require you to write some lines of a simple program. So, be prepared not only to answer questions, but also to demonstrate your technical skills. These are some of the questions that will find your way to your interview for PHP jobs:
- What is Object Oriented Programming?
- In PHP what is the difference between a Class and an Interface?
- What is the difference between a local variable and a global variable?
- In your opinion, what role interfaces play in the design of a program?
- What is your favorite computer language to solve a complex algorithm?
- Would you like to learn a new language? Why?
- Explain how to submit form without a submit button.
- How did you learn to program?
- Describe the process you follow, in detail, when you write Item code.
- Explain the different types of errors in PHP.
- Write a function to determine if a string is a palindrome.
What is Polymorphism? Although this question has nothing to do with the computer, is one of the most typical questions in interviews of programmers. It aims to discover your ability to think logically, which is one of the most important features of any PHP programmer / software engineer. This is simply to check how effectively you can distinguish between objects, which can take on many forms!
Some other questions, which you may be asked, are:
- What role has the index in a database?
- Design a program that reads a student's grades in 5 subjects, store them in a vector and calculate and print their average.
- Design a program that returns an array, the square of the first 200 integers.
- Write the function to calculate the factorial of an integer.
Remember that interviews for such highly technical positions not only demand you to correctly answer the questions, but also matters a lot the way you use to solve problems. The logic is essential when it comes to build or improve any computer programming problem. Good luck for your interview!
