One note though... I would remove 1's, I's, O's and 0's, with some screen's, and fonts, these can look very similar, especially when generating a random password to give to a user. If the password is being used internally, or for a technically advanced individual, or even for some other function (such as a custom password salt) you can always increase the potential password combination's by adding them back in via the $use_custom variable, in which case special char's would be recommended for use anyways, and as well, it can be a bit of work, but non-english char's. Keep up the good work!! Thanks again! big.nerd Excellent Function, thank you!, Also, thanks to ’somebody’ for the optimization.

I mean you open with <?php then you paste the function, then the echo and finally you close php with ?> Good luck! Well… you have to include your function between php tags.
