Although the current PHP market is flooded with a large number of PHP developers, there are only a few of these people who can truly be called masters. Although many companies have recruited some PHP developers, due to low technical level, the company's projects have been piling up. This not only makes the company helpless but also makes the PHP developers who have already joined the job anxious. They also want to take a step closer in the PHP field, but they are unable to find a way to improve themselves. Below, our Ouzai has collected some work of some PHP masters. Methods and habits, let everyone see how the PHP masters work, and I hope these methods can help those who want to take a step closer in the PHP field.

PHP technology improvement experience and methods 

1. Read more manuals and source code

Reading manuals and source code is the best way to improve the technical level of PHP developers. Through a large number of The more PHP development manuals and excellent source codes, the more PHP developers can quickly remember those commonly used variables and functions, which can broaden programmers' ideas and deepen their knowledge level. When you read more, you can quickly clarify your ideas when you encounter some similar difficulties and questions, and you can have more ways to think about some problems. Under a subtle influence, your technical level will naturally improve.

 2. Writing modular code

The codes written by the masters are very clear and very standardized. The code of the module allows them to clearly know which area the thing they are writing belongs to, which also facilitates future modifications.

 3. Code writing specifications

Good code naming should be very standardized, through naming variables and functions, unified methods for accessing the database and handling errors, and the same Code indentation methods, etc. to meet programming standards can make your code more readable.

 4. Write portable code

The codes written by the masters are very highly portable and can run freely in almost any environment.

 5. Write secure code

Good PHP code should be secure. For a professional PHP developer, it is crucial to have a deep understanding of major security vulnerabilities, such as: Cross-site scripting (XSS), Cross-site request forgery (CSRF), code injection vulnerabilities, and character encoding vulnerabilities. By using PHP's special features and functions, such as: mysql_real_escape_string, etc., you can write safe code.

6. Code comments

The degree of code comments can also clearly distinguish PHP masters from novices. The code written by the masters is very readable. From the comments, you can clearly know what the variable or function does, which will be very useful in future code maintenance.

7. Use single quotes instead of double quotes

Use single quotes instead of double quotes for strings in the code to avoid performance degradation caused by variables within the PHP search string.

8. Use comma-delimited string output

Outputting a string separated by commas (,) through the echo statement has better performance than using the string concatenation operator (.).

Some good habits can make your code more readable, and are also a feasible way for you to transform from a PHP novice to a master. So friends who want to go further on the PHP road, start changing now, change your habits, change your working methods, let us start the transformation from PHP novice to master from now on.
