PHP使用星號(hào)替代用戶名手機(jī)和郵箱的實(shí)現(xiàn)代碼

?php 
function hideStar($str) { //用戶名、郵箱、手機(jī)賬號(hào)中間字符串以*隱藏 
  if (strpos($str, '@')) { 
    $email_array = explode("@", $str); 
    $prevfix = (strlen($email_array[0])  4) ? "" : substr($str, 0, 3); //郵箱前綴 
    $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, 0, 3) . "***" . substr($str, -1); 
    } 
  } 
  return $rs;
