PHP序列号生成函数和字符串替换函数代码

PHP 2014-12-01 18:56:17 转载来源: 网络整理/侵权必删

两个函数,如果对你有用,我很高兴。第一个是用来生成序列号,随便改

两个函数,如果对你有用,我很高兴。第一个是用来生成序列号,随便改。第二个是用来“加密”部分字符串,稍微修改一下,就能达到我们在找回密码时经常看到的 itb********@gmail.com 这种隐藏部分字符的效果


/**
* 序列号生成器
*/
function snMaker($pre = '') {
$date = date('Ymd');
$rand = rand(1000000,9999999);
$time = mb_substr(time(), 5, 5, 'utf-8');
$serialNumber = $pre.$date.$time.$rand;
// echo strlen($serialNumber).'<br />';
return $serialNumber;
}
echo snMaker();
/**
* 将一个字符串的一部分替换成某一特定字符
* @param str or int $str 需要处理的字符串
* @param str or int $to 将替换成什么字符串
* @param int $start 保留前几个字符
* @param int $end 保留后几个字符
*/
function hideString($str = 'hello', $to = '*', $start = 1, $end = 0) {
$lenth = strlen($str) - $start - $end;
$lenth = ($lenth < 0) ? 0 : $lenth;
$to = str_repeat($to, $lenth);
$str = substr_replace($str, $to, $start, $lenth);
return $str;
}
echo hideString();
