First, review the concept of a Series: the number of columns in a certain order is called a series... (see Baidu Encyclopedia: Series)Several simple series:1, 1, 1, 1, 1, 1, 1... // series 10, 1, 2, 3, 4, 5, 6, 7... // series 20, 1, 4, 9, 16, 25, 36, 49... // series 3Definition of the generic formula: the relationship between the nth item of the series and the ordinal number of the items, that is, the generation algorithm of the series.The above several series can be expressedAn = F (n) = 1An =
In previous articles, functions are relatively simple in receiving parameters and return types, but they are often more complex in practice. This article mainly describes how to receive parameters from the user space in php extension development and check the type and number of parameters.
1. Use zend_parse_parameters () for automatic type conversion
In php extensions, the easiest way to get input parameters is to use the zend_parse_parameters () fun

I received an email yesterday and learned that I want to attend a product department meeting. I guess it may be because of the demo problem of this product. So I got busy until half past three yesterday, and I realized that I was being played again in the morning. MM sent the email to me by mistake. Miserable reminder! I am still too connected...
However, yesterday, I spent half a day on file operations, obtaining file extensions, removing file extensions, and so on. Now, let's learn from each o

The role of the member methods of a specific class is not described here. The role of the member methods should be better understood by name. Reflection has many functions. reflection can be used to reverse engineer PHP classes or extensions without documents, and obtain related information and comments. Another use is to provide a search class through reflection to obtain all the plug-ins of a specific instance interface.
Here is an example of using PHP

I think most of the eclipse plug-in developers are familiar with the concept of extension points, so when do you decide to create your own extension points? Simple to say my opinion, wrong not to joke.
Why are you talking about this problem? See some of the plug-in development of the first person, do not understand the extension point of the relevant things, als
Five Swift Development Extensions (Extensions)//Extensions Add new functionality (functionality) to an existing class, struct, or enumeration type. This includes the ability to extend a type without having permission to get the original source code (that is, reverse modeling).
