Format Search Results

[bandhole]

I am trying to display search results in a short, user-friendly way.

Is there an way to strip out the words before and after a particular word?

Using these variables:

$txt = "This is a string with a cool word in it";
$key = "cool";
$limit = 2;

I just want $shortTxt to be like this:

$shortTxt = "with a cool word in";

Does a function exist that can do this?

$txt = 'This is a string with a cool word in it';
$key = 'cool';
$limit = 2;

$words = str_word_count($txt, 1);
$position = array_search($key, $words);
$words[$position] = '<font color="red"><b> ' . $key . ' </b></font>';

if ($position <= $limit) {$offset = 0;}
else {$offset = $position - $limit;}

$slice = array_slice($words, $offset, ($limit * 2) + 1);
$shortTxt = implode(' ', $slice);

if ($position > $limit) {$shortTxt = '...' . $shortTxt;}
if ($position < count($words) - ($limit + 1)) {$shortTxt .= '...';}

echo $shortTxt;

That worked brilliantly! Thank you so much.
