Recommended 10 articles for PHP substr () functions

This article describes the use of string length interception in PHP. Share to everyone for reference, as follows: PHP provides a lot of use of functions, where the interception function of the string is no exception, and the function is very powerful. <?php//file encoding format for utf-8$str= ' on the park boat, there's a pretty girl, if something happens in the middle of the lake ... '; Echo mb_substr ($str, 0,7, ' UTF-8 ');//Set the encoding format of the display string// Output ' on the park ship, there's ' Echo mb_substr ($str, 3,7, ' UTF-8 ');//Here Set the encoding format of the display string//output ' on board, there is a drift '?> here the encoding format must be noted that improper handling may be garbled. I hope this article is helpful to you in PHP programming. More examples of truncation of string lengths in PHP

3. Detailed overview of common string methods in C #

Summary: Intercepting a string uses the substring method, which has two overloaded functions in C #: substring (parameter), substring (parameter 1, parameter 2), as follows: string A = "I m a string"; String b=a.substring (1); String c=a.substring (1,6); Where the passed parameter 1 is the starting position of the string, character string B intercepts all characters after the 2nd character of the string A. Character string C will intercept the character of length 6 after the 2nd character of a
