Truncate is a PHP function to create extracts of text, giving various otions for how and where it cuts the text.
Call the function with truncate($type, $string, $length, $break, $pad);.
All options have defaults and so do not have to be specified, except for $string and $length.
$type accepts two options - words or chars.
$string should be passed the string you want to shorten.
$length accepts a numeric value for the number of words of characters (whichever you have set) you want to trim to, eg, '150'.
$break accepts three options - '.', ' ', or '*'. The first two options allow you to trim the text at the first full-stop after the limit is reached, or the end of the next word respectively. The last allows the trim to occur at the next character after the limit.
$pad accepts any string you want to appear after the trimmed text, eg '...'. If you have set $break='.' (or left it at default), then a space is inserted before the $pad character.
