what string manipulation

One, array manipulation1. Initialization of arrays1-1 initialization of one-dimensional arrays:Standard way one: int value[100]; Value[i] has a variable value, not initializedStandard way two: int value[100] = {+}; Value[0] and Value[1] values of 1

1.1 String caseMethod prototypesString .  ToUpper (); Returns the uppercase form of a string conversionString .  ToLower (); Returns the lowercase form of a string conversionFor example, when a user enters a user name, it may be confusing in case of

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.

The method is clever, remove the character C from the string s, just re-assign the value to the S, control the corner mark, and C equals the characters ignored.For example, the new corner labeled J, when S[i]!=c, directly to S[j] assignment is s[i],

String manipulation:String slice: ${var:offset:length}A= "World"The result of ${a:2:2} is: RLTake the last few characters of the string: ${var:-length}Note: There are spaces after the colonTo take a substring based on a pattern:         ${var#*word}:

Some of the commonly used string manipulation features in projects include: intercept string lengths, output conversions, random strings, full-width half-width conversions, character set conversions, mailbox format validation, and digital to file

String manipulation There is a variable: $arr [0] 1, I want to judge its length, both of which have a few characters, how to do it? 2, if I want to take it to the left number two bit, how to do it? Just contact PHP, please teach me
