PHP
function hideStar($str) { //用户名、邮箱、手机账号中间字符串以*隐藏
if (strpos($str,'@')) {
$email_array = explode("@",$str);
$prevfix = (strlen($email_array[0]) < 4) ? "" : substr($str,3); //邮箱前缀
$count = 0;
$str = preg_replace('/([\d\w+_-]{0,100})@/','***@',$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); // substr_replace($name,'****',3,4);
} else {
$rs = substr($str,3) . "***" . substr($str,-1);
}
}
return $rs;
}
?>
