PHP Crypt return *0?

I am the encrypting the password with the crypt function. I have given the Salt value something like this in the database.

randSalt - $2y$10$iusesomecrazystring22 // Database name randSalt

$salt = $row['randSalt'];

$password = crypt($password, $salt)

But when the user submits the form, it's always showing me *0 return in the password field of the database. I am using PHP version 5.6.20 Kindly help me

you should be able to debug the password snippet - possibly using a sandbox for quick response (http://sandbox.onlinephpfunctions.com/). If the password generation is okay with test values, then maybe you're seeing faulty database population. Irrespective, you can break these down and test them separately. you don't need real values to test an insert to the database, and you don't need a database to test password generation.

update: sorry i thought the asterisk was just a random character. From looking at this, i appreciate it's probably an actual response.

I think your salt string is too short. Example generate hash code at https://www.sitepoint.com/password-hashing-in-php/ seems to have 22 characters after the $. I don't really understand the crypt method but it seems to behave different if you shorten the string or add a $ at the end (seems to accept a shorter string, but doesn't apply crypt). I get back *0 when using a too-short string with no trailing $.

Finally, it works, don't know how, but works lol.

Actually, I forget to remove 0 from the user_id database and that is conflicting the other randsalt values. But now everything was setup fine.

Thanks mate for the reply.
