non repeating random number generator

MSSQL has a function CHAR () that converts int (0-255) ASCII code into characters. Then we can use the following MSSQL statement to randomly generate lower-case, upper-case letters, special characters and numbers MSSQL has a function CHAR () that converts int (0-255) ASCII code into characters.

MSSQL Random Number MSSQL has a function CHAR () that converts int (0-255) ASCII code into characters. Then we can use the following ms SQL statement to randomly generate lower-case, upper-case letters, special characters and numbers. Uppercase letters:CHAR (ROUND (RAND () * 25 + 65,0 )) Lowercase letters:CHAR (ROUND (RAND () * 25 + 97,0 )) Special characters:CHAR (ROUND (RAND () * 13 + 33,0 )) Number:CHAR

I have previously told you how to generate multiple random numbers. Next I will introduce how to generate N non-repeated random number instances in php. If you are interested, refer to it. It is not difficult to implement this function, but I have learned a lot. The Code is as follows: Copy code

MSSQL Random Number MSSQL has a function of char () is to convert int (0-255) ASCII code to characters. Then we can use the following MS SQL statement to randomly generate lowercase, uppercase, special characters and numbers. Capital: CHAR (ROUND (RAND () * 25 + 65,0)) Lowercase letters: CHAR (ROUND (RAND () * 25 + 97,0)) Special characters: CHAR (ROUND (RAND () * 13 + 33,0)) Digital: CHAR (ROUND (RAND

Code for generating non-repeated PHPn random numbers. Copy the code as follows :? Phprange is an array consisting of 1 to 100 columns $ numbersrange (1,100); shuffle disconnects the array order immediately shuffle ($ numbers); array_slice obtains the array The code is as follows: // Range is an array of columns from 1 to 100.$ Numbers = range (1, 1,100 );// Shuffle will immediately disrupt the array ord

Copy Code code as follows: Range is to list 1 to 100 as an array $numbers = range (1,100); Shuffle the array order immediately Shuffle ($numbers); Array_slice a section of the array $no = 6; $result = Array_slice ($numbers, 0, $no); for ($i =0; $i echo $result [$i]. " } Print_r ($result); ?> Copy Code code as follows: Range is to list 1 to 42 as an array $numbers = range (1,42); Shuffle the array order immediately Shuffle ($numbers); Arra
