【ThinkPHP】Model基类__contruct方法中的_initialize移动到末尾会产生什么影响?
版本:ThinkPHP 3.1.3
问题:ThinkPHP 中如果在自定义Model里面定义了 _initialize(),那么在这个 _initialize 中无法使用 $this->来查询数据。
我的想法:将Model基类中 __contruct 方法中的 _initialize 移动到该方法的最末尾,这样会产生什么影响?求分析!
文件/ThinkPHP/Lib/Core/Model.class.php,Model 基类__contruct 中的 $this->_initialize 移动到 $this->db... 后会有何影响?
<br /> /**<br /> * 架构函数<br /> * 取得DB类的实例对象 字段检查<br /> * @access public<br /> * @param string $name 模型名称<br /> * @param string $tablePrefix 表前缀<br /> * @param mixed $connection 数据库连接信息<br /> */<br /> public function __construct($name='',$tablePrefix='',$connection='') {<br /> // 模型初始化<br /> $this->_initialize();<br /><br /> // 获取模型名称<br /> if(!empty($name)) {<br /> if(strpos($name,'.')) { // 支持 数据库名.模型名的 定义<br /> list($this->dbName,$this->name) = explode('.',$name);<br /> }else{<br /> $this->name = $name;<br /> }<br /> }elseif(empty($this->name)){<br /> $this->name = $this->getModelName();<br /> }<br /> // 设置表前缀<br /> if(is_null($tablePrefix)) {// 前缀为Null表示没有前缀<br /> $this->tablePrefix = '';<br /> }elseif('' != $tablePrefix) {<br /> $this->tablePrefix = $tablePrefix;<br /> }else{<br /> $this->tablePrefix = $this->tablePrefix?$this->tablePrefix:C('DB_PREFIX');<br /> }<br /><br /> // 数据库初始化操作<br /> // 获取数据库操作对象<br /> // 当前模型有独立的数据库连接信息<br /> $this->db(0,empty($this->connection)?$connection:$this->connection);<br /><br /><br /> //假如把_initialize移动到这里会产生什么影响?<br /> //$this->_initialize();<br /> }<br /><br />
------解决方案--------------------
initialize 的本意是初始化
而 _initialize 既无参数也无返回,显然并不能干预预定流程的执行
所以放在哪里都无所谓

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.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
