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 $words;
}
Instead only words, this works for sentences.
So no half sentences anymore:
<?php
function substr_sentence($string, $start=0, $limit=10, $max_char = 300)
{
/* This functions cuts a long string in sentences.
*
* substr_sentence($string, $start, $limit);
* $string = 'A example. By someone that loves PHP. Do you? We do!';
* $start = 0; // we would start at the beginning
* $limit = 10; // so, we get 10 sentences (not 10 words or characters!)
*
* It's not as substr()) in single characters.
* It's not as substr_words() in single words.
*
* No more broken lines in a story. The story/article must go on!
