The function of string manipulation in PHP3.0 is much more, and it is important to have the following: (1) echo,print,printf,sprintf Used for the output string. If there is a variable name in the string, it is replaced with its value. The latter two functions are similar to C's with the same name function. 　 (2) STRC

string.Reset S N: Changes the nth string to S.Print N: Prints the nth string of output.Printall: Prints out all strings.Over: End operation.Where n,x,l can be composed of find and rfind operation expressions, S,S1,S2 can be composed of copy and add operation expressions.InputFirst behavior an integer n (n between 1-20)Next n behaves n strings, strings do not contain spaces and operation commands, and so on

When looking at some open source code, we often see some string manipulation functions, which are available under the Linux platform, but MS is not provided on the Windows platform. Therefore, the software must be implemented by itself. Common Library functions are:Obtains a copy of the current character, freeing the memory externally.

Concat () – combines two or more characters of text to return a new string.IndexOf () – returns the index at the first occurrence of a substring in a string. If there is no match, returns-1.CharAt () – returns the character at the specified position.LastIndexOf () – Returns the index of the last occurrence of a substring in a string, or 1 if there is no match.Match () – checks whether a

negative argument to the length of the string---> // This is : substr (7,5), which intercepts 5 characters from position 7 // "Rld" // convert the second argument to 0 // That is : substr (3,0), which is to intercept 0 strings from position 3, returns an empty // ""3. IE compatibilityIf the substr () method passes a negative value, there is a problem, and the original string is returned. IE9 fixed this is

of a string: StringBuilder.The class encapsulates a mutable string, in other words, when we need to change the contents of the string, we do not create a new object, but rather modify it on the basis of the original object. This reduces the overhead of memory.2.2. Using Append to implement appendStringBuilder Append (String
