核心函数
//用户名、邮箱、手机账号中间字符串以*隐藏
function hideStar($str) {
if (strpos($str, '@')) {
$emAIl_array = explode("@", $str);
$prevfix = (strlen($email_array[0]) < 4) ? "" : substr($str, 0, 3); //邮箱前缀
$count = 0;
$str = preg_replace('/([dw+_-]{0,100})@/', '***@', $str, -1, $count);
$rs = $prevfix . $str;
} else {
$pattern = '/(1[3458]{1}[0-9])[0-9]{4}([0-9]{4})/i';
if (preg_match($pattern, $str)) {
$rs = preg_replace($pattern, '$1****$2', $str);
} else {
$rs = substr($str, 0, 3) . "***" . substr($str, -1);
}
}
return $rs;
}
使用方法：
hideStar($变量);
