Technique #1
<?php
function trunc($phrase, $max_words) {
$phrase_array = explode(' ',$phrase);
if(count($phrase_array) > $max_words && $max_words > 0)
$phrase = implode(' ',array_slice($phrase_array, 0, $max_words)).'...';
return $phrase;
}
?>
Technique #2
function limit_words($words, $limit, $append = ' …') {
// Add 1 to the specified limit becuase arrays start at 0
$limit = $limit+1;
// Store each individual word as an array element
// Up to the limit
$words = explode(' ', $words, $limit);
// Shorten the array by 1 because that final element will be the sum of all the words after the limit
array_pop($words);
// Implode the array for output, and append an ellipse
$words = implode(' ', $words) . $append;
// Return the result
return $words;
}
