It’s no secret that PHP is the most popular server-side programming language for web applications. Due to its simplicity, this language attracts many newcomers. After studying the basics, they rush to all kinds of freelance websites, littering the web application market with projects whose further development is practically impossible. For clients, it is better to do it all over again from scratch than to support the already existing code. Many take money from customers and start doing projects that they cannot deal with, thereby spoiling the impression of freelancers.
But as you know, experience comes with practice. So in order to master web development, you need to deal with it and constantly improve yourself. In this article, we would like to give some advice to novice webmasters on how to write code based on the experience of professionals. And if during your studies you experience difficulties, make sure to ask AssignmentCore to do programming homework for you. All you need is to pay coding experts online to have your programming assignments completed within the deadline you need.
1. Read the Language Documentation Well
Many programmers who use such languages as CC ++ and Java, when there is a need to develop server-side scripts for a web resource, using C-like syntax of PHP, begin to create code based on their experience in application programming. PHP itself unloads the variables from memory when it reaches the end of the script/function, so deleting the array is a completely unnecessary operation. It is better to spend several hours reading the documentation in detail and write code that will not create problems for people who will use it in the future.
2. Do Not Use Old Language Constructs
The fact is that PHP, like all popular languages, is constantly evolving. New designs and functions appear that should improve the performance of your applications. Older, slower, and less efficient ones are marked by the developers of the language as obsolete. So, for example, writing a script in PHP 5.2 can cause errors and crashes when your project runs on a newer version of the language. So do not forget to follow the innovations.
3. Do Not Reinvent the Wheel
If you have a task, think about whether someone had to do it before you. It is possible that this one was already created with your language itself by another developer.
4. You Need to Be Paranoid
Always check the data received from the client for its authenticity. Just remove the HTML, clean the quotation marks, slashes, convert it to a number, and only then substitute this into the request, not earlier.
5. Write a Universal Code
When you have a task that can be applied somewhere else in another project, it is advisable to place it in a separate function, or even in a separate module. And do not forget about the advice written in paragraph 3.
6. Do Not Complicate the Code
The code you write should be as simple and understandable as possible for other people. Also, it should be understandable for you because you will probably return to the old project a year later.
7. Do Not Forget to Comment
Well, everything is simple here. Just comment on important points in the code. Draw up comments on classes, properties, methods, and functions, preferably in the PHPDoc format.
8. Do Not Forget about OOP
PHP 5 is a full-fledged OOP language. Therefore, when designing a project, do not forget about it. The class hierarchy will not only allow you to easily extend the code but also simplify the use of already written code in other projects.
9. Learn Programming Patterns
Programming patterns are a separate wide topic that will allow you to more clearly understand the principles of OOP programming and avoid design mistakes. Especially you need to get acquainted with the MVC pattern.
10. Do Not Use PHP Means for Tasks That Can Be Done with SQL Means
The fact is that SQL queries are executed at the driver level and work several times faster than PHP. In MySQL or another DBMS, there are enough built-in functions and constructions to do everything you need. For example, to find out the number of records, you can use the SQL COUNT function.
Conclusion
In this article, the most essential and useful things that are needed for new developers were listed and discussed. And they will be especially useful for those who just start learning. One of the advantages of the profession is that everyone can master web development. Learning from scratch is suitable even for those who do not have any specialized education and work experience. You just need to have perseverance, some time for lessons and homework, a computer with Internet access, and the ability to install specialized programs. We wish you all success in training and developing your projects.
