Need code for making htpasswd

[perficut]

I've gotten stuck and need a little help.

 

I a variable (LastName) that I need to convert to an htaccess crypted password to put into the htpasswd file.  The code I am getting is similar to TG3UomYd9nEOgGary:V2/EvyXHE8h.Q   sometimes even longer.  Not to mention it doesnt work.

 

When I use some of the online htpasswd creators i found on google, I am getting crypted passwords such as cwIgR6n88Pt3E  much shorter. This crypted password works fine when I put it into the htpasswd file.  The one I am getting does not.

 

As you can see, the FirstName is the LOGIN ID, the LastName is the Password

Heres what I have.

// OPEN PASSWORD DATA FILE AND STORE USE NAME & PASSWORD //

$myFile = "../private/.htpasswd";
$fh = fopen($myFile, 'a') or die("can't open file");
$prepassword = ($LastName);
$password = crypt($prepassword, base64_encode($prepassword)); 
$stringData = "$FirstName:$password";
fwrite($fh, $stringData);
fclose($fh);

// CLOSE PASSWORD DATA FILE .HTPASSWD //
