php crypt with same salt returns same crypted string, why?

$crypted_withq = crypt('12345678q','salt');
$crypted_withoutq = crypt('12345678', 'salt');

echo $crypted_withq;
echo '<br/>';
echo $crypted_withoutq;

It returns same output.

How can i store different crypted password in database with php?

The answer is right in the documentation:

 

 

 

It also only uses the first eight characters of str, so longer strings that start with the same eight characters will generate the same result (when the same salt is used).

 

You should be using the password_hash function.
