Highlighting Keywords In a Return…

Anon

Hello,

I want to highlight certain words form a db return. The value is stored into a var, so I would need to parse through the string to change keyword(s) in that string. For example, if some does a search on cat, I want to return a description.

Description: The cat went for a walk in the park…

Is there a way to slap in html tags?

Thanks for any suggestions…

str_replace()?

if you want to highlight cat:
$keyword="cat";
$str="The cat went for a walk in the park…";
$str=eregi_replace($keyword, "$keyword", $str);

One thing is that you don't want partial words highlighted. If "cat" is a keyword, you probably don't want highlighting like "grasscather"!.

$highlightedstring = preg_replace("/\b$var\b/i","$var", $rawstring);
The 'i' assumes the searches are case-insensitive. If they're not, drop it. The \b represents a "word break" and makes sure that "grasscather" doesn't happen.
