I am trying to write a little search script to search a mysql db.
I would like to highlight the search words for the displayed results, like
sourceforge etc...
After a little help, I have got it to hightlight when searching for one
word. The problem is if I do a search for more than one word it repeats the
hightlighting.
here's the code I got so far
$bg = explode("%",$string);
while($db->next_record())
{
$title = $db->f("title");
$des = $db->f("description");
for($z=0; $z < count($bg); $z++)
{
if(next($bg) == false)
{
reset($bg);
}
$bgstring = current($bg);
$title = preg_replace("/($bgstring+)/ie", "'<span
class=highlight>\\1</span>'", $title);
$des = preg_replace ("/($bgstring+)/ie", "'<span
class=highlight>\\1</span>'", $des);
}
echo $title.NL;
echo $des.NL.NL;
}
The problem is is I search for class or span it screws up the code as it
replaces the span or class in the original tag.
How could I stop this?
I know this another rex ex thing and I'm gonna get the oreilly book when I'm
next in the city but untill then it's driving me bonkers.
TIA
