PHP development practice has reached a new level. Nowadays, every working process is already automated, and it is no longer needed to create a certain engine from scratch. Therefore, the development process itself is pleasant and almost problem-free now. The only thing that will always cause new questions and thereby force developers to find out new and convenient tools for their solution is the creation of web applications for the needs of customers.
In our today’s article we want to cover the basic principles and features of a modern development on PHP and its related technologies. Also we would like to give your some tips how to make your work with PHP application projects more comfortable and efficient.
1. What is with PHP code?
Regardless of the technology you decide to use, the code is a key indicator of the quality of the future application. PHP is a dynamic programming language and its syntax and structure are particularly compact. There are some recommendations for PHP code writing:
- Adhere to the harmonization – the unified style of code not only helps the system to process it in the right way, but also improves its understanding by other specialists. It is important to remember that a well-formatted and documented code saves time and money and is pleasant for reading.
- Manage your code better by using version control systems, for example GIT.
- Do not forget about such good practice as the open source code writing of your application or one of the modules. It will recommend you as a cool developer, ready to dedicate your experience and experience, or make a great advertising for your company, if it is a group project.
2. PHP testing
It should be noted that earlier projects based on PHP technologies always differed in the low quality of automated testing. Fortunately, progress forges ahead, and now the situation has changed for the better. It is also crucial not to forget that the application, provided with a large number of tests, will work much more efficiently, and it has such advantages, as follows:
- easy refactoring process of its software;
- unit testing allows to use a module developing style;
- inclusion in the tests of not only code parts, but also its documentation.
Speaking about PHP dependencies, it is absolutely necessary to use such tool as Composer. There the code is is closely associated with libraries and their different versions, so that’s why it is important to know that your dependence is already included in GIT. Do not forget to check all the dependencies so that you do not add everything to the repository two times.
It is also useful to strive for modular programming in order to avoid repetition of the code (including incorrect cases), and also to disclose the source code of these modules.
Actually, it is one of the key questions – storing all the settings of your application. If you need to transfer the application’s code, you must save not only the correct program operation, but also the security of all data. Therefore, the use of so-called environments like Apache or SetEnv to store all the settings is an excellent practice.
Tips: many variable environments have a lot of high-level arrays and other complicated information. You will be able to work with easily if you transfer it to JSON, encode it in base64 and stay storing in the appropriate database.
5. Working with resources
App resources usually include all the used services such as databases, queues, caching system, repositories, mail stores and others. The golden rule is to create the abstracted access to all resources, and the degree of the abstraction depends on your preferences (for example, if you are planning to expand your application, you need to use the local resources adapter). The placement of resources should be specified in the application settings.
Tips: weak coupling is also one more important part of abstraction development. All services without which the application can work should be easily disconnected. We recommend you to set up automated shutdown when there are any problems with the service or even without them.
6. DevOps in PHP development
It is good when the entire development process is smooth and does not cause big problems. The app passes all tests, the structure is logical and understandable, there are no bugs… Isn’t it a miracle? But then suddenly there are complaints from the customer and the standard claim ‘it does not work’. Why is it so?
We recommend that you keep in mind the philosophy of devOps. When working on a specific project, you should always think about what technical requirements and capabilities of the equipment on which the application you create will work. Pass tests, the structure is logical and understandable, no bugs … Is not it a miracle? But here comes such Working on a specific project, always think about what technical requirements and capabilities of the equipment on which the application you created will work.
It is possible to see a stunning paradox in PHP technologies progress. Everything has become more complicated and it is not enough just to be able to write code for the development: you should also know the design patterns and follow the strategies of application testing, placing and using. And at the same time it is easy to work with all the necessary tools that make development process absolutely fast-working, efficient and qualitative.
