Want to hire freelance PHP developers on your own? Here are the skills you must look for while hiring a PHP developer
Hiring freelance PHP web developers might be an intricate task for you if you are a non-technical manager. Today, PHP is one of the evergreen server-side languages for developing web applications and is used as a general-purpose programming language. Hiring dedicated PHP developers among thousands of developers is a challenging task for anybody. So, here Ultragenius comes to assist you while recruiting freelance PHP developers on your own. Ultragenius understands your job requirements and gets you only the most skilled developers who have strong foundation of PHP.
The following core skills you must ensure while hiring a freelance PHP developer –
Strong knowledge of core PHP functions
The PHP developers must be well-acquainted with the core inbuilt functions because it is one of the most effective tools used in programming. Some of the popular functions you must ask while hiring a freelance PHP developer are –
- Array – array(), is_array(), in_array(), array_merge(), array_keys(), array_key_exists(), array_shift(), array_push(), array_pop(), array_values(), array_map(), array_unique(), array_slice(), array_diff(), array_search(), array_reverse(), and array_unshift().
- String – substr(), strlen(), str_replace(), trim(), strpos(), strtolower(), strtoupper(), is_string(), and strstr().
Some other frequently used PHP functions are count(), date(), htmlentities(), htmlspecialchars(), strip_tags, addslashes, stripslashes, explode, implode, rand(), str_replace, strlend(), array_combine(), array_multisort(), array_unique(), print_r().
Experienced with Object-Oriented Programming (OOPS) Concepts -
Object-Oriented Programming (OOPS) is a software-development approach concerned with real-world objects, such as vehicles, banks, employees, etc. OOPS mainly comprises of –
- Encapsulation – Encapsulation is binding the data members and functions that expose only the functions in the class and hide the private members.
It is an important concept used widely in software development and helps reduce software complexity, protect the internal state of an object as accessing the variables/members is possible through getter and setter methods. Also, the implementation inside methods can be changed without breaking the code which is using that class.
- Inheritance – Inheritance is a real-time demand of every code which allows one class to extend the functionality of another class. The core feature of Inheritance is Re-usability. The class inheriting the class is called the child class or subclass and the class that is being inherited is called parent class or superclass. Instead of thousands of lines of code every time, developers can utilize the same code in inheriting classes as well.
- Abstraction – Abstraction is the process of defining the core functionalities of any class, hiding its implementation details. It tells what a class does instead of how it does. Here, you can ask the difference between Encapsulation and Abstraction, the former shows the inner implementation, and the latter shows the outer implementation. For example, take the example of a mobile phone, Encapsulation is how the display screen and keypad button are connected using circuits while Abstraction is any user can dial a number using the display screen and keypad button.
- Polymorphism – Polymorphism is the ability of any data to take more than one form. It is of two types – Compile-time Polymorphism and Run-time Polymorphism.
In compile-time polymorphism, function overloading is implemented in which one function with the same name can have a different number of arguments and different return types.
In run-time polymorphism, function overriding is implemented in which the child class / sub-class decides the implementation of the parent class / base-class function.
Well-versed with PHP frameworks
While hiring a PHP developer, check his/her knowledge of PHP frameworks, like Laravel, CodeIgniter, Magento, etc. CodeIgniter is an open-source PHP web development framework that allows faster web development by providing fully-featured database classes with the support for several platforms. CodeIgniter provides developers an easy approach to utilize modular functions and renders excellent migration support.
Laravel is used for developing server-side web applications and provides in-built authorization and authentication system, used for sessions, caching, and developing RESTful API services. Besides, Laravel is very useful for handling traffics on websites.
Highly Experience in working with Version Control System (VCS)
Developers must have a very in-depth knowledge of version control systems. Developers mostly use Git for their work, which helps the development team collaborate and organize your code. Git also simplifies reviewing old codes with newly updated ones by helping to pull the code from its repository and managing commit history. Along with this, PHP developers need to know how to use commands like add , push , pull and commit as well as branching, merging – it allows them to work independently on the code
PHP Testing tools and Frameworks
- PHPUnit is one of the widely used unit-testing frameworks in PHP. It provides various advantages like code coverage analysis, logging, mocking objects, etc. PHPUnit gives developers the advantage of writing test cases for all functions and methods, so if a bug occurs at any point then it can be easily identified. PHPUnit’s test results are customized and used in testing various types of controllers without extending.
- StoryPlayer is another mostly used PHP testing framework used for testing both front-end and back-end web applications.
- Codeception is also a very popular testing framework because of its test execution speed.
Understanding of databases
Connecting PHP with a database is very essential to deliver highly unique solutions for a project. To create a dynamic website with PHP, the developer must know combining it with a database like MySQL, PostgreSQL, or MongoDB.
Knowledge of CRUD operations on a database and commands like SELECT, INSERT, UPDATE, ADD, etc. is required to know for a freelance PHP developer.
Experience with web markup and UI, UX Concepts
The developer must have a firm understanding of element positioning, displaying the elements, and making components interactive, semantic markup, and other related UX Concepts so they can design the product with the best quality. The developer must be experienced in developing visual effects in presentational markup. For, example – How the heading appears, making text larger and putting weight to it, and giving which color to it, and which markup can include captions, bind columns, and row headings to table cells.
Proficient in writing optimized and readable code
You must hire the PHP developers based on their ability to write clean and optimized code that is understandable by all the team members, and is scalable.
