symfony2-创建提交表单生成数据过程

一、”一对多“关系

表shop（一）

表comment（多）

保存有shop_id

orm关系

Shop.orm.xml

Comment.orm.xml

二、首先我们来手动生成shop 和comment的关系

第一种情况（可以生成）

controller中

可以生成表，对应关系

表shop

表：comment

因为这里shop表中的comments，其实并没有在shop表中有字段，这里只是一个记号，表示用来取comments方便。比如$shop->getComments();而且添加comment时方便。

第二种情况（不可以生成）

如果改变addComments函数呢

不能生成表对应关系

表：shop

表：comment

为什么呢？

因为comment表id并没有和shop关联起来（即真实comment表中没有存上shop的id）

第三中情况：（可以生成表关系）

表：shop

表：comment

直接用往comment中添加shop

好了，其实还有“多对多”关系？

提交表时，如何自动生成一对多时关系？

下次说吧

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

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.

How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

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.

Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AM

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.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AM

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: An Introduction to the Server-Side Scripting LanguageApr 16, 2025 am 12:18 AM
