If you want to manage throughout the website:
unction custom_excerpt_length( $length ) {
return 28;
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );
Or in each case:
in function.php:
<?php
function string_limit_words($string, $word_limit)
{
$words = explode(' ', $string, ($word_limit + 1));
if(count($words) > $word_limit)
array_pop($words);
return implode(' ', $words);
}
?>
Where you want to display the excerpt:
p><?php
$excerpt = get_the_excerpt();
echo string_limit_words($excerpt,25);
?></p>
