PHP5.2下preg_replace函数的问题
preg_replace 使用的超过了php5.2默认允许的字节 Discuz!6.0.0正式版程序发布以来，大家都热火朝天的升级中，但是部分插件在6.0下出现了问题 下面说下我的解决过程，希望能给大家一些建议吧 第二步：怀疑是bank.htm这个模板书写格式的问题，于是我很郁闷的开始分析模板，说实话，模板大了分析起来真的很头疼。结果显然又没有找到原因。比较郁闷的说 第二步：然后发现将此模板拆分以后，就正常执行了，这时候我初步怀疑是不是正则匹配的bug在大数据量的时候出现了错误，于是我就上bugs.php.net开始搜索了http://bugs.php.net/search.php?c … ace&x=3&y=5在这里找啊找啊找，于是终于找到了这里http://bugs.php.net/bug.php?id=39405，突然间发现居然是5.2配置的问题，在调整大pcre.backtrack_limit和pcre.recursion_limit之后问题解决 之所以写这么详细就是想一起分享下我解决问题的思路：）
也就是pcre.backtrack_limit和pcre.recursion_limit的大小的问题。
比如http://www.discuz.net/viewthread.php?tid=559133这个银行插件
在php为5.2.0及以上的环境下安装以后会出现白屏的问题
从Discuz!用户的角度考虑，我们需要去协助插件作者解决这个问题
第一：此插件在5.5的情况下可以正常运行，但是6.0下就白屏了
Discuz!6.0为了增加模板缓存文件的可读性，增加了缓存文件的缩进，而确实修改过部分templates.func.php的模板处理部分，
莫非是这个原因？开始我初步确定是这里的问题，因为用5.5的部分代码替换修改过的代码，就表现正常，但是很郁闷的没有找到原因

Tips for dynamically creating new functions in golang functions
Apr 25, 2024 pm 02:39 PM
Go language provides two dynamic function creation technologies: closure and reflection. closures allow access to variables within the closure scope, and reflection can create new functions using the FuncOf function.

What are the benefits of C++ functions returning reference types?
Apr 20, 2024 pm 09:12 PM
The benefits of functions returning reference types in C++ include: Performance improvements: Passing by reference avoids object copying, thus saving memory and time. Direct modification: The caller can directly modify the returned reference object without reassigning it. Code simplicity: Passing by reference simplifies the code and requires no additional assignment operations.
What is the difference between custom PHP functions and predefined functions?
Apr 22, 2024 pm 02:21 PM
The difference between custom PHP functions and predefined functions is: Scope: Custom functions are limited to the scope of their definition, while predefined functions are accessible throughout the script. How to define: Custom functions are defined using the function keyword, while predefined functions are defined by the PHP kernel. Parameter passing: Custom functions receive parameters, while predefined functions may not require parameters. Extensibility: Custom functions can be created as needed, while predefined functions are built-in and cannot be modified.
C++ Function Exception Advanced: Customized Error Handling
May 01, 2024 pm 06:39 PM
Exception handling in C++ can be enhanced through custom exception classes that provide specific error messages, contextual information, and perform custom actions based on the error type. Define an exception class inherited from std::exception to provide specific error information. Use the throw keyword to throw a custom exception. Use dynamic_cast in a try-catch block to convert the caught exception to a custom exception type. In the actual case, the open_file function throws a FileNotFoundException exception. Catching and handling the exception can provide a more specific error message.
