In actual projects, we may need to use Chinese characters to generate pinyin into a database. For example, to generate a pinyin url for news titles, or to splice the category items for easy query, there are many application scenarios. My current

Differences between strlen () and mb_strlen () in PHP. Common functions used in php to calculate the string length include strlen and mb_strlen. when the characters are all English characters, the two are the same. Here, we will mainly compare the

Calculates the number of characters private function countstr ($str) {$cclen =0; $asclen =strlen ($STR); $ind =0; $HASCC =ereg ("[Xa1-xfe]", $STR); Determine if there is a Chinese character $hasasc=ereg ("[x01-xa0]", $STR); #判断是否有ascii字符if ($HASCC &&

This article mainly introduces the PHP custom function to achieve statistical Chinese string length method, combined with the case of a summary analysis of PHP for the Chinese judgment, coding and operation related operations skills, the need for

Php splits a string randomly into arrays of different lengths. Php splits a string randomly into arrays of different lengths. This document describes how php splits a string randomly into arrays of different lengths. We will share with you how php

When communicating with the client and the server, there is a common scenario that is passed back and forth through an ID as a URL parameter. Assuming that there is only this ID identified in the business, then a slightly more secure communication

Test instructions: To make this string symmetrical at an interval, the minimum number of characters to add (the symmetry here is ABCABC, not ABCCBA)First think of is Len-next "Len", then to deal with him, set D=len-next "Len", then len%d, if ==0,

//directly by conversion comparison;function Num1 ($STR) {$num = strlen ($STR);$res = ";for ($i =0; $i if (Strtolower ($str [$i]) = = = $str [$i]) {$res. = Strtoupper ($str [$i]);}else{$res. = Strtolower ($str [$i]);}}return $res;}echo NUM1

Test instructions is still very simple, we can use DFS poor to cite all possible names, it is important to query the name is not legal, the beginning of the map, did not expect to time out, so the back of the dictionary tree, in fact, should also be

When a pointer object is inside a class, there is a crash problem because a shallow copy is pointing to the same piece of memory by two objects! To solve this, a deep copy, write-time copy is introduced.1. Shallow copy (new open a pointer to do

To get the first letter of the method there are many, this we generally want to divide the Chinese characters and then converted to pinyin, and then use SUBSTR to take the first letter, below I found online two instances, different people together

Because the tool requires us to write a function that can generate random strings. I think there should be a lot of such random string generation functions on the internet. Baidu has a bunch of functions. below I will summarize them for you. Because

Analysis: It's not a problem. It's just a tough question. It's better to make changes and use STL to solve it easily.   Code Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--> # Include

This is a very impressive, I just contacted ACM, thought it was a water problem (because it is Chinese, short), has not been made. Now think about it too. may also be my previous string mastery is not good;This problem can also be used in the STL
