Dedecms常用函数解析
大家都知道,dedecms支持[field:senddate function=”strftime('%y-%m-%d %H:%M',@me)”/]这样的一些用法,即标记内使用function,调用相关的函数对当前标签返回的内容进行再次处理再显示出来。
就拿上面这个标记为例子,本来程序显示数据库某个表的字段senddate,但通过查看数据库发现,senddate只是一大串数字,并不是我们想要的时间格式,PHP语言本身对时间处理是有一些自带的函数,strftime就是php本身自带的函数,当然你也可以扩展,自己编写自己的函数,模板上我们不需要显示这些数字,我们需要按照一定格式转换为我们的时间,这时候就可以使用这个函数进行处理了。
下面我们来分析下dedecms自带一些常用函数的使用方法:
■GetCurUrl()
这个估计用到的不是太多,这个函数获得当前运行的脚本地址,使用时候可以通过下列方式:
{dede:CurUrl runphp='yes'}
@me = GetCurUrl();
{/dede:CurUrl}
■GetAlabNum()
返回半角数字的,如果你某个字段信息不希望出现全角数字,可以使用这个函数,例如:
[field:listnum/]返回的是12234,我希望是半角数字12234,可以这样使用函数:
[field:listnum function=”GetAlabNum(@me)”/]
■Text2Html()
文本转HTML,函数将文本内容中的空格、…等字符转换为HTML标记,可以这样使用:
[field:textcontent function=”Text2Html(@me)”/]
同样这里也有个相反的函数,将html转换为Text的,Html2Text(),其用法类似
■ClearHtml()
清除html标记,函数将内容中包含的html标记清除。用法:
[field:content function=”ClearHtml(@me)”/]

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. These technologies are useful in customizing HTTP routers, implementing highly customizable systems, and building pluggable components.

In C++ function naming, it is crucial to consider parameter order to improve readability, reduce errors, and facilitate refactoring. Common parameter order conventions include: action-object, object-action, semantic meaning, and standard library compliance. The optimal order depends on the purpose of the function, parameter types, potential confusion, and language conventions.

The key to writing efficient and maintainable Java functions is: keep it simple. Use meaningful naming. Handle special situations. Use appropriate visibility.

1. The SUM function is used to sum the numbers in a column or a group of cells, for example: =SUM(A1:J10). 2. The AVERAGE function is used to calculate the average of the numbers in a column or a group of cells, for example: =AVERAGE(A1:A10). 3. COUNT function, used to count the number of numbers or text in a column or a group of cells, for example: =COUNT(A1:A10) 4. IF function, used to make logical judgments based on specified conditions and return the corresponding result.

The advantages of default parameters in C++ functions include simplifying calls, enhancing readability, and avoiding errors. The disadvantages are limited flexibility and naming restrictions. Advantages of variadic parameters include unlimited flexibility and dynamic binding. Disadvantages include greater complexity, implicit type conversions, and difficulty in debugging.

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.

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.

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.
