mssqlphputf-8Garbled charactersandrightofcodingConvertquestion

After using php + mssql for a while, I feel that mssql’s support for encoding is not very good (actually I am not sure yet), but I haven’t had the time to change the database urgently, so I can only make do with it, and I am submitting data again today. An error occurred.

Since the submitted ntext field contains a lot of content, about 220 KB, I misunderstood it and thought it was an error caused by the article being too long. When I looked at the php configuration, I found that php’s support for mssql.textsize is already at 400 K. Why is there still an error? After turning on the error, I discovered that it was not the article that was too long, but an error caused by the encoding. The error is as follows:

代码如下	复制代码
Notice: iconv() [function.iconv]: Detected an illegal character in input string in...。

My English is really bad, I just know that there is something wrong with the iconv() function. Google Translate said that illegal characters were detected in the input string. A sudden realization.

Go to the Internet to find a solution to the problem based on the error message, which is to add //IGNORE to the second parameter of iconv(), which means to ignore the error. The code is as follows:

代码如下	复制代码
iconv("utf-8", "gbk//IGNORE", $str);

Tested and submitted successfully.

Note: Netizen experience shows that the range of gbk is larger than gb2313, so the error rate of encoding with gbk is smaller than that of gb2313.

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
