如何替换mysql数据库中  A字段中  \,.这样的英文标点符号


回复讨论(解决方案)

update table set A = replace(A,'\\,.','你要替换的值') where ...
Copy after login
Copy after login

where 后面的省略号是什么意思。
我之前

update table set A = replace(A,'\','') 
Copy after login
Copy after login

这样写的就替换不掉。

这样才行

update table set A = replace(A,'\\','')
Copy after login
Copy after login
Copy after login
Copy after login

要??
$sqlstr = "update b set url=replace(url,'\\\\,.','')";
mysql_query($sqlstr) or die(mysql_error());

update table set A = replace(A,'\\,.','你要替换的值') where ...
Copy after login
Copy after login

update table set A = replace(A,'\','') 
Copy after login

好的。我的一个网站,用的飞飞cms做的视频网站。但是有的标题里面出现了\ , 等这样的英文字符,导致视频在程序解析的时候出现错误,播放不了,这个问题是我后期才发现的,所以之前很大一批数据都存在这个问题。如下图


所以我想通过替换数据库将这些多余的字符替换掉,以便于视频可以正常解析播放。

数据库表 ff_vod 播放地址这个内容字段是 vod_url


要??
$sqlstr = "update b set url=replace(url,'\\\\,.','')";
mysql_query($sqlstr) or die(mysql_error());



按照你这样写的,替换不成功



??我是上????的。



要??
$sqlstr = "update b set url=replace(url,'\\\\,.','')";
mysql_query($sqlstr) or die(mysql_error());



按照你这样写的,替换不成功



??我是上????的。



如果我的数据库表 ff_vod 字段名 vod_url 要替换\为空 按照你这个应该怎么修改编写啊。帮给写个完整的,谢谢。我怕我写的出了一点误差,谢谢

图中显示的只是 1 个 \ 字符,而你主贴中描述的是 \,.
目标错了,结果怎么能正确呢?

在 sql 控制器里

update table set A = replace(A,'\\','')
Copy after login
Copy after login
Copy after login
Copy after login
是正确的
在 php 里,因为要放在双引号中
$sql = "update table set A = replace(A,'\\\\','')";
Copy after login
Copy after login

才是正确的
4 个 \ 经 php 处理后变成 2 个 \ 传递给 mysql

$sqlstr = "update b set url=replace(url,'\\\\','')";mysql_query($sqlstr) or die(mysql_error());
Copy after login
Copy after login

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,

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.

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.
