[SOLVED] replacing a certain number of chars with stars

[dennismonsewicz]

I am wanting to display a password but say like the first 4 letters in the password (not necessarily the first 4, could be the last 4) I want to display as asterics...

 

anyway of doing this?

[xtopolis]

echo "****" . substr($password, -4);//show last 4 pw chars

echo substr($password, 0, 4) . "****";//show first 4 pw chars

substr

 

That is a simple way, based on what you provided. (I could be off by 1 in the 2nd ex.)

ah gotcha... cool thanks man!

[ratcateme]

for first 4:

echo "****" + @substr($password,4);

the @ will suppress any errors caused if the password is less than 4 chars long

 echo @substr($password,0,4)."****";

will start the last 4

but as many users on this forum will tell you stroing passwords in plain text (or even encrypted with reversible encryption) is EXTREMELY bad practice and output putting them (or part of them) is even WORSE

you should be using MD5 encryption with a salt for password storing

and never output passwords or even the MD5 encryptions
