遇到的问题

i am try to change a fuction from php to golang . the function job is use chr,ord,base4_encode to encode some string。php generate a serial int number, like 122|234|135|138|179|19|190|183|80|156|4|159|195|213|86|241|140|7|112|23|61|182|37|91|185|26|203|185|206|206|183, some number biger than 127,the ascii bigest number is 127. now, the probrem is: php's chr(206) is not equivalent golang's string(rune(206))

please help me,thx

The results in PHP and Go are different because, as the documentation for each states, PHP's chr returns the ASCII character for its argument, whereas Go's rune uses UTF-8. Below 127, ASCII and UTF-8 are the same, but above that, they differ.

PHP和Go中的结果是不同的，因为作为每种状态的文档，PHP的chr返回其参数的ASCII字符，而Go的符文 使用UTF-8。低于127，ASCII和UTF-8相同，但高于ASCII和UTF-8，则不同。

为了和php一直则需要

• 一个可以执行的php文件 think_encrypt.php

<?php

    function think_encrypt($data, $key = '1231231', $expire = 0) {
        $key  = md5($key );
        $data = base64_encode($data);
        $x    = 0;
        $len  = strlen($data);
        $l    = strlen($key);
        $char = '';

        for ($i = 0; $i < $len; $i++) {
            if ($x == $l) $x = 0;
            $char .= substr($key, $x, 1);
            $x++;
        }

        $str = sprintf('%010d', $expire ? $expire + time():0);

        for ($i = 0; $i < $len; $i++) {
            $str .= chr(ord(substr($data, $i, 1)) + (ord(substr($char, $i, 1)))%256);
        }
        return str_replace(array('+','/','='),array('-','_',''),base64_encode($str));
    }

    $param_arr = getopt('a:');
    echo think_encrypt($param_arr["a"]);
?>
