PHP实现累加校验和
这里有一个用 PHP 实现累加校验和的示例代码:
<?php
/**
* Compute the checksum of a given input string using the additive checksum algorithm.
*
* The additive checksum is calculated by summing up the ASCII values of all the characters in the input string.
* The result is then converted to a hexadecimal string.
*
* @param string $input The input string to compute the checksum for.
* @return string The hexadecimal representation of the additive checksum.
*/
function computeAdditiveckcksum(string
