Strange problem with the length of the field gotten from database [duplicate]

by

Found the problem. when I did this:

echo strlen($hash)

it printed 90, which is strange because there were definitely no spaces at the end when I printed out the success/failure message, and the field has a varchar length of 255

I added this line:

$hash = substr( $hash, 0, 60 );

And now it works fine.

Its strange that no one else seems to have run into this issue. There are similar posts about password_verify, but none of them required this type of conversion, or any conversion for that matter:

php password_verify not working

password_verify php not match

Using PHP 5.5’s password_hash and password_verify function

One thing that bothers me is this prevents the code from being forward compatible. How will I know that the hash is 60 characters long when the default changes?
