Program One: Php intercept Chinese string method
Because the homepage and VTIGERCRM often in the interception of Chinese characters garbled (using substr), today found a better way to intercept Chinese strings, in this share with you.
Copy to ClipboardWhat to refer to:
[www.bkjia.com]function Msubstr ($str, $start, $len) {
$tmpstr = "";
$strlen = $start + $len;
for ($i = 0; $i if (Ord (substr ($str, $i, 1)) > 0xa0) {
$tmpstr. = substr ($str, $i, 2)

The CHR function is used to convert an ASCII code to a character, the Ord function is used to convert a character to ASCII ASCII code that is the computer can display the character encoding, its value range is 0-255, including punctuation, letters, numbers, Chinese characters and so on. In the programming process, the specified characters are often converted to ASCII code for comparison. The following is a function that PHP provides to convert ASCII c
is not a good alternative to enumeration.
The second method is frequently mentioned by some famous experts. We can call it "Object enumeration ". Create a class for the enumeration, and then use the public class object to express the value of each enumeration. As follows:

Dear friends, Hello, I am Qin Yuanpei. What bloggers want and share today is the use of disunity to extract Unity3d game footage. This tool, bloggers in the Unity3d game development of the anti-compilation Assetbundle extract game resources This article has actually been mentioned, but because some friends on how to use this tool is still a problem, So the blogger decided to write an article to explain how to use disunity to extract material from the Unity3d game.Preparatory work

execution efficiency (enumeration is an integer, there is no efficiency loss ). But he cannot meet conditions 1 and 2. What is its definition ?? Close ?? Plaque? Ne? How can I step on a bucket? What kind of yellow slice Can I copy to the address? Java programmers use it, but it is not a good alternative to enumeration.

An interesting question
In the test room, hash the code into an integer, multiply the value of the last asicc Code * 1 by * 10, get an integer, and then rank nlogn in disorder using the equality and uniqueness.
The proof is as follows:
For plaintext ABCDE
Ciphertext bcdef
There are (a-B) * 10000 + (B-c) * 1000 + (c-d) * 100 + (D-f) * 10 + (e-f) * 1 = a constant
We can pre-process this constant. For any f [a, B], A, and B belong to lowercase letters, we can pre-process the value.
Okay, this is th

So I can take the data by byte, mainly using the Ord function to get the byte ASCII code.
$type = Ord ($memstr {4});$state = Ord ($memstr {5});$ip = Ord ($memstr {6}). Ord

Furthermore, we output the data to a file and use winhex to view the data status.
File_put_contents ('./dd.txt', $ memstr );
Use winhex dd.txt to view hexadecimal data.

As a data middle layer, memcache is often used for data exchange.
For example, in a system, we define the following user status information. Each user only needs to exist in 52 bytes.Key state # ID, for example, "state #10888"Value: (binary data)User ID Uint32Type User Type Uint8:State user status Uint8:Server IP Uint32Last online time Uint64Session ID length Uint16
Session ID char [32]
A total of 52 bytes
So how can we get the above data through memcache in php?
The stored data contains binary
