The usage of mb_strlen is similar to that of strlen, except that it has a second optional parameter for

Very good PHP coding specifications. note: This shows the coding specifications from the PHPCMS development documentation. Although the code is called the PHPCMS development specification, I think this applies to all PHP programming. After writing so many PHP codes, many codes may not be able to compare and correct the codes in the future. Phpcms Coding Specification 1. introduction .... 2 2. applicability .... 2

function in a functional language, such as an outgoing/incoming parameter and a common variable.Unlike imperative programming languages, functional programming languages have some special concepts. We will discuss them separately:Anonymous Functions In functional programming languages, a function can have no name. An anonymous function usually indicates "a piece of code that can accomplish something ". This expression is useful in many cases, because we sometimes need to use a function to accom

find the next one, you need the program to find the primary key. Also, fixed-length tables are more likely to be cached and rebuilt. However, the only side effect is that a fixed-length field wastes some space, because the field is set to allocate so much space whether you use it or not. Using the "vertical split" technique, you can split your table into two that are fixed-length and one that is indefinite.8 , choose the right engineMySQL offers many
