Convert an irregular name=value pair string into a formatted array.

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.

One of best and unknown built in string function included in .NET is String.Split(). It has come in quite handy for my in the last 2 years that I thought I'd share. Pretty basic example here...and for my first post, I thought I'd throw in a little File IO (for free of course)! This was written in .NET 2.0 and it will take little to no modification to make it work in 1.0/1.1.
