Things you often do and think about

Obscure if condition

1) Processing of ||

                                                                                                             

 

While reducing the number of lines of code is a good goal, minimizing the time required to understand the code is an even better goal.

Return value

                                                                                                                                                                                                                                                                                                   Rather than using such an empty name, choose a name that describes the value or purpose of the entity.

              $alias declares that this variable is used to carry aliases - indicating the purpose of this variable. And may help us find defects

A good name should describe the purpose of the variable or the value it carries.

Temporary variable

The $ i here is "my temporary variable", which is specifically used to increase the statistical data automatically and avoid duplication of statistical points. But the most important thing about $i is not the temporary variable. Use charset_index to represent "the subscript of my statistical data", which is more "descriptive".

Loop iterator

I also found bad smell in my js code.

I variable name is very empty, so don't do it.

Names like i, j, iter and it are commonly used as indexes and loop iterators. Although the name is vague, everyone knows that they mean "I am an iterator". - Actually if you use these names to mean something else, it would be confusing. So don't do it.

If you insist on using vague names like i, j, it, then you must have a good reason to convince yourself.

Summary

When we are coding, if we spend a few more seconds to come up with a good name, you will find that our "naming ability" will quickly improve.

I usually think of a Chinese name first. If I really can’t think of a corresponding English name, I will use a translation tool to paste the Chinese name that comes to mind, and then cut out the named variable or function name.

Give me a gift with a nice name I saw recently

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
