preg-replace Function - Word Boundry and Case Insensitive

[mmelen]

How do I add case insensitive feature to the preg_replace function. I read that it is "/i" but exactly where do I add it?

$main[] = "/\b".$row['main']."\b/"; 
$linkedarticle = preg_replace($main, $keyword, $article, 1);

$main[] = "/\b".$row['main']."\b/i";

Additionally, preg_quote may come in handy as you're dynamically building your pattern.

$main[] = "/\b".$row['main']."\b/i";

Haha perfect, thanks!
