Spring is a powerful Java application framework. It is widely used in Java applications and provides enterprise-level services for plain old Java objects (pojo. Spring uses the dependency injection mechanism to simplify work and improve testability. The configuration file (usually in XML format) specifies spring bean, dependencies, and services required by bean. However, these xml configuration files are lengthy and not practical. It is difficult to read and manage large projects that need to de
PHP specification1. Why Coding Specifications• Coding Specifications (Code conventions) are particularly important for programmers for several reasons:1. In the life cycle of a software, 80% of the cost is spent on maintenance.
2. Almost no software is maintained by its original developers throughout its lifecycle.
3. Coding specifications can improve the readability of the software, allowing programmers to understand the new code as quickly and tho
Text /For readability purposes header ("Content-type:text/plain"); //Save and Display tree echo $dom->savexml (); ?>
Note the SaveXML () method of the DOM document object. I'll explain this in detail later, and now you just need to realize that it's used to output the current snapshot of an XML document to a file or browser. In this example, to enhance readability, I have exported the ASC

Before you go on, take a look at the concept of "liner" and "sans serif".
The alphabet system in Western countries is divided into two categories: Serif and sans Serif.
Serif is a serif font, which means that there are additional decorations at the beginning and end of the stroke, and that the strokes are of a different thickness. Conversely, Sans serif do not have these extra decorations, and the strokes are about the same thickness.
Serif fonts ar
When processing XML-based applications, developers often need to establish XML-encoded data structures. For example, in the Web, XML status templates based on user input, XML statements for server requests, and customer responses based on runtime parameters.Although the construction of XML data structures is time-consuming, everything becomes simple and clear if you use mature php dom application interfaces. This article will introduce you to the main functions of the php dom application interfa

In the field of software engineering, the uniform style of source programs marks maintainability and readability, and is an important part of software projects. At present, there is no written coding style document, so many times, progra

Remember to add the qualifier to the end of the name.Common opposites in variable namesCorrect use of battle words. By applying naming rules, we can improve the consistency of the w
So today, I have sorted out the PHP specifications for your reference. As the saying goes, "the rules are dead and people are living .". Yes, but people who grow up in rules will have a bunch of very enviable good habits.

meaningless contextsFor example, the application (gas station Deluxe) is referred to as GSD, so adding the same prefix for each function, class, variable is not a good idea to name the GSD. Address is a good name, but if you need to differentiate it from a MAC address, port address, or Web address, you should use PostalAddress, Mac, and URI to make the name more accurate.16. SummaryThe hardest part of naming a word is the need for good descriptive skills and a common cultural background try the
BMP format, the next 8 bytes to record the length of the file, and then the next 4 bytes to record the length of the BMP file header. As you can see, the encoding is based on value (indefinite length, 2, 4, 8 byte long values have), so BMP is a binary file.2. text file and binary file accessWhat is the process of opening a file with a text tool?

This article mainly introduces the use of CSS font-size-adjust properties to improve the page layout, with a certain reference value, interested in small partners can refer to
The Font-size-adjust property in CSS allows developers to specify font-size based on the height of the lowercase letters, which effectively improves the readability of the page text.
In this article, you can not only understand the importance of the Font-size-adjust attribute,

When working with XML-based applications, developers often need to create XML-encoded data structures. For example, XML state templates based on user input in the Web, server request XML statements, and customer responses based on run-time parameters.
Although the construction of XML data structures is time-consuming, if you use the mature PHP DOM application interface, everything will become straightforward. This article introduces you to the main features of the PHP DOM application interface,

1. Crowded text: Word spacingThis is a mistake that can easily be overlooked, where the word spacing is too crowded to reduce the readability of the text. Some fonts themselves will be sparse, or too tight, properly adjusted to an easy-to-read state.2. Dense paragraph: line spacingLine spacing is also an important factor affecting readability
