Use VarDumper for elegant PHP Debugging From: https://jellybool.com/post/a-brand-new-way-to-test-php-with-symfony-va... I believe that many PHP developers often use the var_dump () function when writing code. many people will directly use a function similar to die (var_dump ($ var )) to check what a variable or instance looks like. some people may also encapsulate it directly, for example, a vdd, this allows you to use it when debugging your cod

This article has been published by the author Wu Weiwei authorized NetEase Cloud community.Welcome to NetEase Cloud Community, learn more about NetEase Technology product operation experience.The necessary condition for writing an elegant program is a good design.Writing a program is like walking a maze. At the beginning of the writing, there are several possible solutions that linger in our minds. We choose one that continues in depth and may reach t

For example, there is a function () function find($conditions = null, $sort = null,..（很多参数）.., $fields = null, $limit = null) Now I just use the first and the last parameter, usually find (' xxx ', ' ', ', ',..., ' xxx ') is not very good to see, there is no elegant point of writing it?

Today to review the previous code, suddenly found that the insertion sort with the binary search algorithm implementation is very awkward, so try to rewrite one, did not expect quite smooth, a few minutes to write and test passed:static int BinarySearch (int[] array, int value, int start, int end) { if (start = = end) return start; var middle = (start + end)/2 + 1; if (value >= Array[middle]) return BinarySearch (array, value, middle, end); else return BinarySear

: defines an interface for creating an object ( imobilephone Factory ), let the subclass decide which class to instantiate. factory method delays the instantiation of a class to its subclass. Well, the above is a brief Implementation of factory method partten (this is not the key ). We can see what needs to be done to implement such a model. Is there any more elegant implementation method. In fact, using anonymous classes in Java can b

Segment errors or other errors that cause the program to quit has always been like an unreasonable bounder, the process of our painstaking development of wanton destruction, leaving a big or small core files let us have a headache, we wept after the silent bear this sorrow ...Segment error generated by the SIGEGV, can be captured by the user, also gives us the opportunity to save the program important data, borrow glibc a function to deal with a SIGEGV idea, we can turn the segment error into a

Personal Understanding:The so-called elegant programming is to drink coffee, touch the keyboard, thinking about business;The elegant code is defined as:1, as far as possible less single double quotation marks;2, do not nest;3, the name is all the most basic English words;4, the code, like English, is a paragraph;5, an application code organization clear, preferably a tree relationship, network relationship

In the previous article, the Goto statements in C language were elaborated in depth. In fact, The Goto statements are the most primitive support for exception handling programming in process-oriented and structured programming languages. Later, in order to better and more easily support the exception handling programming mechanism, programmers can write more efficient and friendly code modules with the exception handling mechanism in C language programs. Therefore, there is a more

Python uses the CMD module for more elegant running scripts and pythoncmd module scripts This example describes how to use the CMD module to run scripts more elegantly in Python. Share it with you for your reference. The specific analysis is as follows: It is inconvenient to debug some things for testers. Although some scripts are written. The cmd module of python provides a more elegant way. I just wrote s

neccecary } I personally think this method is not elegant enough. In Asp.net, I tried to avoid using events as much as possible. I would rather do loop traversal in the data source able for some annoying or simple processing. First, because vs2003 has poor support for web standards, and I am used to working in the Html source code mode, it is extremely troublesome to add an event to the DataGrid. Second, I am not very worried about its performance, a
