[RESOLVED] trim and centre text

[owaring]

i have a search script that displays results in a table.
i do not wish to use the whole of the resulting text, and would like to trim it to 200 chars or so, 100 either side of the search term.

i have come up with the following as a somewhat crude solution;

$chars = split($search_term, $search_result, 2);
$chars[0] = strrev($chars[0]);
$chars[0] = str_split($chars[0] , 100);
$intro = '.....'.strrev($chars[0][0]);
$chars[1] = str_split($chars[1] , 100);
$outro = $chars[1][0].'.....';

echo $chars[0].$search_term.$chars[1];

i'm hoping someone can provide me with a better way, as i'm not too pleased with it!!
at least i tried!

This will avoid starting/ending in the middle of a word:

// in this example, the search word is "example"
preg_match('/\b.{0,100}\bexample\b.{0,100}\b/is', $text, $matches);
echo $matches[0];

Thanks NogDog, that's much nicer!!

one last thing!!.....
how can i get this html stripping code to allow <br> to pass?

$pagecont = preg_replace('@<[\/\!]*?[^<>]*?>@si', '' , $pagecont);

Don't know if this would meet your needs, but you could use [man]strip_tags/man:

$pagecount = strip_tags($pagecount, '<br>');
