Encrypted signature Algorithm (code) between PHP data

This article brings you the content is about PHP data encryption between the signature Algorithm (code), there is a certain reference value, the need for friends can refer to, I hope to help you.

    /**     * Signature generation algorithm     * @param  An associative array of the collection of request parameters for the array $params API call, does not contain the sign parameter     * @param  string $secret The signed key is the session returned when you get access token secret     * @return string returns the parameter signature value *    /Private Function getsignature ($params) {        $secret = $this->secretkey;        $str = ";  String        to be signed//the parameter is sorted in ascending order of the dictionary order of its parameter name        ksort ($params);        Iterates through each key/value of the sorted parameter array to        foreach ($params as $k + $v) {            //for Key/value to generate a key=value-formatted string, and stitching it $str after the string to be signed            . = $k. $v;        }        The signature key is stitched to the last face of the signature string        $str. = $secret;        Generate a MD5 signature for the signature string using the MD5 algorithm, which is the sign parameter value we want to append        return MD5 ($STR);    }

which

this->secretkey; It can be a two-program-ready encrypted character.
