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.

This is a bare-bones DB connectivity class. It's really just meant to abstract a few basic mysql_ functions so that if you ever have to change DBs you don't have to change every database function call.
I really just threw this together on a whim with no testing what-so-ever. Also, it only abstracts the most basic MySQL functions--this is intentional; please expand it as you see fit.
