Reusable library code can be applied to the storage of a contract and can be used to implement complex data structures.LogAt the block level, data can be stored in a special, indexable structure. This feature is called a log, and solidity uses it to implement events. The log data cannot be accessed after the contract is created, but the data can be accessed efficiently from outside the blockchain. Because part of the log data is stored in the Bron filter (Bloom filter), we can sear
Object-oriented programming (OOP) is a fundamental skill of our programming, and PHP5 provides good support for OOP. How to use the idea of OOP for advanced programming of PHP is very meaningful for improving PHP programming ability and planning a good web development architecture. In this example, we illustrate the practical meaning and application of programming oop using PHP.When we do a Web site with a database background, we will take into account that the program needs to be applied to dif

It is somewhat similar to matching a specific type of character. With "\ B", there is naturally "\ B", which is used to match characters that are not at the boundary.

. When these 9 characters are combined, it matches the character string in the same order as the expression and at the same position as the corresponding character (in fact, it is a string exactly the same as the expression ).
Because this matching method is the least flexible, it can only match exactly the same characters, so it is also called "full match ".Additional reading

Www.google.com

Www.bkjia.com

As you can see, for the expression "www.bkjia.com", the "bkjia" section is a full-text match, and can only be fixed to match the "bkjia" string; ". ", can match any single character (including the character". ).
Greedy)
It will match as many characters as possible. It first looks at the entire string. If it does not match, the string is reduced. If it encounters a possible match, it stops shrinking and expands the text. When a matching text is found, it does not rush to save the match to the matching set, but expands the text until it cannot continue matching or expand the complete string, save the last matched text (also the longest) to the matching set. So it is greedy.
