[英]How to hide characters of a name by X?
I want to display only first three and last three characters of a name. 我只想显示名称的前三个和后三个字符。 Other characters should be hidden by X.
其他字符应由X隐藏。
For example, 例如,
$name = "ELVIS MASTAINE KANGABAM";
I want to echo the above name like the following: 我想像上面这样呼应上面的名字:
$hidden_name = "ELVXX XXXXXXXX XXXXXBAM";
echo $hidden_name;
Please help! 请帮忙! Thank you!
谢谢!
You could use substr and concatenation eg: 您可以使用substr和串联,例如:
$hidden_name = substr($name ,0, 3). str_repeat("x", strlen($name)-6) . substr($name , -3);
echo $hidden_name;
I use preg_replace on all aZ chars from substr 3 -> -3 and replace them with X. 我在substr 3-> -3的所有aZ字符上使用preg_replace并将其替换为X。
$name = "ELVIS MASTAINE KANGABAM";
$hidden_name = substr($name, 0,3) . preg_replace("/([a-zA-Z])/", "x", substr($name,3,-3)) . substr($name, -3);
echo $hidden_name;
