[英]php how can i hide a part of the email adress?
i currently have this: 我目前有这个:
$value = preg_replace('@hotmail.com', '***********', $value);
$value = preg_replace('yahoo.com', '***********', $value);
$value = preg_replace('outlook.com', '***********', $value);
$value = preg_replace('mailinator.com', '***********', $value);
$value = preg_replace('live.com', '***********', $value);
$value = preg_replace('live.nl', '***********', $value);
but how can i show e email adress like this: juliankuit* * ** * *** ? 但是我如何显示这样的电子邮件地址:juliankuit * * ** * *** ? email is: juliankuitert@hotmail.com
电子邮件是:juliankuitert@hotmail.com
and without having to replace all the email providers like hotmail.com with * 's 而且不必用*替换所有的电子邮件提供商,例如hotmail.com
thanks in advance! 提前致谢!
echo preg_replace('/(?<=.).(?=.*@)/u','*','TestEmail@Google.com');
将返回
T********@Google.com
I'm using this function 我正在使用此功能
function maskEmail($email, $minLength = 3, $maxLength = 10, $mask = "***") {
$atPos = strrpos($email, "@");
$name = substr($email, 0, $atPos);
$len = strlen($name);
$domain = substr($email, $atPos);
if (($len / 2) < $maxLength) $maxLength = ($len / 2);
$shortenedEmail = (($len > $minLength) ? substr($name, 0, $maxLength) : "");
return "{$shortenedEmail}{$mask}{$domain}";
}
This an example 这个例子
echo maskEmail('abcdfghi@example.com'); // abcd***@example.com
My PhP is too rusty to put code example, but here's the logic I would use : 我的PhP太生锈了,无法放置代码示例,但这是我将使用的逻辑:
@
symbol index in string 2) @
符号索引) *
to the string you obtained in step 2 *
Note that during step 2, if X <= 0, then the whole string should be replace by *
characters 请注意,在步骤2中,如果X <= 0,则整个字符串应替换为
*
字符
Sometimes its good to show the last character too. 有时也很适合显示最后一个字符 。
I will suggest you keep things simple. 我建议您保持简单。 Maybe something like this is simple enough https://github.com/fedmich/PHP_Codes/blob/master/mask_email.php

Masks an email to show first 3 characters and then the last character before the @ sign 屏蔽电子邮件以显示前3个字符,然后显示@符号前的最后一个字符
ABCDEFZ@gmail.com becomes A*****Z@gmail.com ABCDEFZ@gmail.com成为A*****Z@gmail.com
function mask_email( $email ) {

$char_shown = 3;
$mail_parts = explode("@", $email);
$username = $mail_parts[0];
$len = strlen( $username );
if( $len <= $char_shown ){
return implode("@", $mail_parts );
}
//Logic: show asterisk in middle, but also show the last character before @
$mail_parts[0] = substr( $username, 0 , $char_shown )
. str_repeat("*", $len - $char_shown - 1 )
. substr( $username, $len - $char_shown + 2 , 1 )
;
return implode("@", $mail_parts );
}
