1. What is XML-RPC?
XML-RPC is a format designed by Userland Software company: it is a format designed to use HTTP protocol transfers XML format file to obtain remote procedure call (Remote Procedure Call) transmission method. The official website is www.xmlrpc.com.
There is a PHP XML-RPCFramework(Collection of classes) is used to use PHP Language to write XML-RPC client and server. The current stable release version is 2.2, and the download address of is http://sourceforge.net/projects/phpxmlrpc/files/phpxmlrpc/2.2.2/xmlrpc -2.2.2.tar.gz/download. In addition, you can also find other s language
XML-RPCwww.xmlrpc.com ??> list, such as Perl, Python. This article will introduce the use of XML-RPC for PHP
class library. 2. System Operation Requirements
The design goals of this class library are scalability and backward compatibility. Therefore, it supports most existing PHP
versions. The minimum required PHP version is 4.2. This library provides a compatibility layer to support PHP 4.0.5 and 4.1. Of course, the official recommendation is to use PHP 5.0 or higher. Note that if you want to use SSL or HTTP 1.1 to communicate with the remote server, you must put "CURL” extension is compiled into PHP. In addition, the native "xmlrpc" extension that comes with PHP is introduced here The XML-RPC class library is not the same thing, so there is no need to compile it into PHP. 3. Introduction to related classes 1.xmlrpcval There are six basic types in XML-RPC Two composite types, the basic types are: int, boolean, string , double, dateTime.iso8601, base6, the composite type is: array, struct. The function of Xmlrpcval is to convert the types in PHP into these types and put them into XML-RPC for transmission. Related methods: scalarVal()：如果$val->kindOf()=="scalar",則直接返回改對象的PHP對應(yīng)的值。 2.xmlrpcmsg 相關(guān)函數(shù)： 相關(guān)方法： 相關(guān)方法： 四，一個實際例子 在服務(wù)度的interface.php中： 在客戶端的client.php中： 敢死隊2在線觀看<span

Object-Relational Mapping (ORM) Performance Tuning in PHP
Jul 29, 2025 am 05:00 AM
Avoid N 1 query problems, reduce the number of database queries by loading associated data in advance; 2. Select only the required fields to avoid loading complete entities to save memory and bandwidth; 3. Use cache strategies reasonably, such as Doctrine's secondary cache or Redis cache high-frequency query results; 4. Optimize the entity life cycle and call clear() regularly to free up memory to prevent memory overflow; 5. Ensure that the database index exists and analyze the generated SQL statements to avoid inefficient queries; 6. Disable automatic change tracking in scenarios where changes are not required, and use arrays or lightweight modes to improve performance. Correct use of ORM requires combining SQL monitoring, caching, batch processing and appropriate optimization to ensure application performance while maintaining development efficiency.

Laravel raw SQL query example
Jul 29, 2025 am 02:59 AM
Laravel supports the use of native SQL queries, but parameter binding should be preferred to ensure safety; 1. Use DB::select() to execute SELECT queries with parameter binding to prevent SQL injection; 2. Use DB::update() to perform UPDATE operations and return the number of rows affected; 3. Use DB::insert() to insert data; 4. Use DB::delete() to delete data; 5. Use DB::statement() to execute SQL statements without result sets such as CREATE, ALTER, etc.; 6. It is recommended to use whereRaw, selectRaw and other methods in QueryBuilder to combine native expressions to improve security

CSS uses: root to define bright theme variables, .dark-mode class defines dark theme variables, and applies these variables through var(); 3. JavaScript detects prefers-color-scheme and reads localStorage to determine the initial theme; 4. Switch the dark-mode class on the html element when clicking the button, and saves the current state to localStorage; 5. All color changes are accompanied by 0.3 seconds transition animation to enhance the user

go by example generics
Jul 29, 2025 am 04:10 AM
Go generics are supported since 1.18 and are used to write generic code for type-safe. 1. The generic function PrintSlice[Tany](s[]T) can print slices of any type, such as []int or []string. 2. Through type constraint Number limits T to numeric types such as int and float, Sum[TNumber](slice[]T)T safe summation is realized. 3. The generic structure typeBox[Tany]struct{ValueT} can encapsulate any type value and be used with the NewBox[Tany](vT)*Box[T] constructor. 4. Add Set(vT) and Get()T methods to Box[T] without

css dropdown menu example
Jul 30, 2025 am 05:36 AM
Yes, a common CSS drop-down menu can be implemented through pure HTML and CSS without JavaScript. 1. Use nested ul and li to build a menu structure; 2. Use the:hover pseudo-class to control the display and hiding of pull-down content; 3. Set position:relative for parent li, and the submenu is positioned using position:absolute; 4. The submenu defaults to display:none, which becomes display:block when hovered; 5. Multi-level pull-down can be achieved through nesting, combined with transition, and add fade-in animations, and adapted to mobile terminals with media queries. The entire solution is simple and does not require JavaScript support, which is suitable for large
