Regex help with search function

We are trying to make a search function but got a bit stuck when it came too Regex. What we got is.


$concat = preg_replace("/($word)/i","<strong class=\"searchWordFound\">$1</strong>",$concat);

We need to convert these to a Regex that does not search for $word [i]inside[/] HTML tags or their attributes.

The reason for this is that if I do a search for ex “a e” when the function does the second round of the above preg_replace it will add a new <strong> tag around the e inside searchWordFound. Same with “a o”, “e a” etc.

Is that doable at all?

Your best bet is probably the DOM functions but it can be complicated. You can do something similar in a JavaScript that runs after the page is loaded.

try this maybe:
$concat = preg_replace("/>([^<]*)($word)([^<]*<)/i","$1<strong class=\"searchWordFound\">$2</strong>$3",$concat);
Needs to be beween a > and a <, like eg. between <html> and </html> or <body> and </body> - if not, just add a > and a <, and then get rid of 'em again.
