MySQL 5.x Stored Routines, PHP Session Values, a little CSS oh my! Complex to set up but easy to impliment. Geared toward security, simplicity (of use) and convenience.

This is a random password generator that produces understandable passwords based on word lists. I've only included a 3 entry world list because you should chose a list based on your password requirements and your users. If you need to generate passwords that are 14 characters in length, you will want a different list than if you're generating 8 character passwords. And depending on your users, you may want to use certain lists. The list I use is about 4000 words that are 5-7 characters long, all well-known words that have had potentially objectionable content removed. For security reasons I don't want to include this list.

A note on security: though this generates relatively strong passwords for the average user, they are particularly susceptible to brute-force attacks. This is even more an issue if somehow your word list gets compromised. I would not recommend using this function for anything where a highly secure password is needed.

A note on choosing your list: You'll also see that I've built the system to avoid generating passwords with zeros and ones in them. This is because zero and upper-case "o" can be confused as can one, lower-case "L" and upper-case "i." When choosing my word list I was also sure to strip out all words that start with the letter "o" or "i" (to prevent the optional ucfirst() from creating 0/O and I/1 confusion) and words that contain the letter "L" (to prevent l/1 confusion). I find that this greatly helps with preventing confusion, but again weakens the security of the passwords some. It's your choice.

Set a word or phrase in an input field, clear it onfocus

This function calculates how many lines will text occupy.
Example (simple):


$string = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Phasellus tincidunt posuere dolor";

$num_lines = how_many_lines(10, $string);

It accepts a third, optional, parameter $options, that allows you to change behaviour. $options should be array. Following configuration options are available:

'white_spaces' - default: array(' ', "\t") - array of chars, that should be treated as whitespace.

'new_lines' - default: array("\r\n", "\n") - array of strings, that should be treated as newlines. For example, for HTML you can set 'new_lines' => array('');

'force_line_breaks' - default: true - force wrapping, when the token is longer than width, or not. If set to false, and token cannot be fitted into $width, function will return false;

'callback' - default: null - callback function for determining character width. Must accept at least one parameter - $char

'callback_params' - default: array() - optional additional callback parameters

'char_widths' - default: null - associative array in a form $char => $width, which contains char width. If $char is not found in the array, it's width is defaulted to 0.

Strip HTML

For those times you need to do a loop in PHP, but have the outcome be in descending order (ie, start at 10 and end at 1).

This little function will split an e-mail address passed to it at the @ sign, and make sure that there is a valid e-mail server at the other end =)
