PHP Htpasswd writer for Apache. You can add or delete users or you can update their passwords.

• Supports crypt, md5 and sha1 algorithms
• Locks the htpasswd file to prevent conflicts while writing.
• Throws an error on invalid usernames.
• Tested on windows and debian (apache only)
• Whole htpasswd file is read into the memory so be careful if you have lot's of users (In fact you should consider a different kind of authentication mechanism if you have that much users)

$htpasswd = new Htpasswd('.htpasswd');
$htpasswd->addUser('ozan', '123456');
$htpasswd->updateUser('ozan', '654321');
$htpasswd->deleteUser('ozan');

Apache htpasswd can be encrypted in three ways: crypt (unix only), a modified version of md5 and sha1. You can define the encryption method when you're setting the password:

$htpasswd->addUser('ozan', '123456', Htpasswd::ENCTYPE_APR_MD5);
$htpasswd->addUser('ozan', '123456', Htpasswd::ENCTYPE_SHA1);

(Yes, you may use different algorithms per user in the same passwd file...)

Make sure that you use either ENCTYPE_APR_MD5 or ENCTYPE_SHA1 on windows servers as "crypt" is not available on windows.
