Hi,
Don't have time at the moment to test out your code (hopefully someone else
will), but you may want to have a look at the str_shuffle() function, since
all you're doing is randomizing a known string.
Something like:
$key_chars =
str_shuffle('abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'
);
$random_password = substr($key_chars, 0, 15);
...should do the trick.
Can't comment on the randomization performed by str_shuffle, though, and do
you honestly need 50 million predetermined passwords?
Regards,
Murray
