This article mainly shares with you a piece of PHP code for creating a graphic verification code, which is very practical and can be used at will: Myvcode. class. php: class that encapsulates the verification code /** File: myvcode. class. php*

This article describes how to extract the verification code in php168_cms. For more information, see The code is as follows: Function yzImg ($ nmsg ){If (function_exists ('imagecreatetruecolor ')){$ Imstr [0] ["s"] = $ nmsg [0];$ Imstr [1] ["s"]

Php verification code The code is as follows: // File header...Header ("Content-type: image/png ");// Create white paper with true color$ Im = @ imagecreatetruecolor (50, 20) or die ("image creation failed ");// Obtain the background color$

Use Rand () in MySQL to generate random numbers with random numbers and random name strings. Use Rand () in MySQL to generate random numbers with random numbers and random name strings. Preface:The RAND function returns a random floating point

Project requirements: The program randomly generates arithmetic calculation questions, and after the user fills out the answer to determine the correct answer.Pair member: Li QiaoTask assignment: The algorithm thought and the main function adopted

For example, a random value rand (range: 1-100) is generated ). The probability of a small value in rand is very high, but the probability of a large value is very low. I hope you can give a specific formula. The random value can be replaced by rand.

Here's the one that doesn't have a jamming code. The following is the class code Copy CodeThe code is as follows: /************************************************ File:imagecode Done: Generate Dynamic Captcha class DATE

Copy CodeThe code is as follows: $arrF = Array (); $arrS = Array (); $intTotal = 100; $intRand = 10; for ($i =0; $i { $arrF [] = rand (1, $intRand); $arrS [] = rand (1, $intRand); } $arrT = Array_merge ($arrF, $arrS); $arrRF = Array (); $intStart =

Since the initial values of the parameters in my algorithm are given randomly within a certain range, the boss said to run several times to calculate the mean and variance of the results to reduce the impact of randomness, I ran 10 times to find out
