ThinkPHP 转换数据库查询出的数据到对应类型

Jun 20, 2016 pm 12:32 PM

默认情况下,Thinkphp查询出的所有字段值类型都是String,如果是开发web,当然没问题,但开发接口,就很麻烦了,总不能让客户端去转类型。

ThinkPHP的Model.class.php时,提供了_parseType方法,可以在查询完以后,做类型转换,但框架没有这么干,需要我们手工调一下。

写一个Model基类:

BaseModel.class.php,因为我用到关联查询,所以继承自RelationModel

use Think\Model;use Think\Model\RelationModel;class BaseModel extends RelationModel{    //在查询后,转换数据类型    protected function _after_select(&$resultSet, $options)    {        parent::_after_select($resultSet,$options);        foreach ($resultSet as &$result) {            $this->_after_find($result, $options);        }    }    protected function _after_find(&$result, $options)    {        parent::_after_find($result,$options);        foreach ($result as $field => $value) {            $this->_parseType($result, $field);        }    }}
Copy after login

所有的Model类继承自BaseModel.

本来,这样已经搞定了,但发现Model.class.php的_parseType方法里有个低级bug,看图:

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
