How to convert string to character in PHP

How to convert a password string to a specified character, for example *or something else.

I am currently working on a password change page. I would like to display the password on the page, and I want someone not to pass the password, so I want to hide the password string until the character type *with the same length. An example, for example <input type="password" />.

Sorry for my bad english ...

If you are looking for an easy way to simply create an asterisk string equal to the password length:

$modified = str_repeat( "*", strlen( "secretpass" ) );

echo $modified; // **********

HTML, (*). str_repeat:

<?php
$password = "MyPasswordThatIWantToMask";
$maskedPassword = str_repeat("*", strlen($password));
