Hi Erwin,

Yep, this does exactly what str_replace does. 

How can I make the whole thing case insensitive:

$result= "This Is A Test, Isn't It?"
$search= "IS"

It will include the 'is' in 'This', and also the 'Is' and the 'is' in

Try the following one:

$result = "This is a test, isn't it?";
$search = "is";

$result = preg_replace( '/(' . $search . ')/i', "<span
class=\"highlight\">\$1</span>", $result );
