PHP uses asterisks instead of user names, mobile phones and mailboxes. In many active interfaces, you will see that the Alipay numbers of some customers in Taobao's shopping interface are hidden. Let's take a look at how to use it. 


<?php 
function hideStar($str) { // The middle string of user name, email address and mobile phone account is used to * Hide  
  if (strpos($str, '@')) { 
    $email_array = explode("@", $str); 
    $prevfix = (strlen($email_array[0]) < 4) ? "" : substr($str, 0, 3); // Mailbox prefix  
    $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; 
} 
?> 
<?php 
$account = "phpfensi.com"; 
$email = "416148489@qq.com"; 
$phone = "18005152525"; 
?>
