How can I replace this code

[teguh123]

$Query404=eregi_replace("index.htm$","",$Query404);
$Query404=eregi_replace(".html","",$Query404);
$Query404=eregi_replace(".htm","",$Query404);
$Query404=eregi_replace("[\/\-]"," ",$Query404);
$Query404=eregi_replace("[_]"," ",$Query404);

PhP says that eregi will be gone. So what should I replace that with?

I want that to be case insensitive.

So should it be become

$Query404=preg_replace("index.htm$","",$Query404);

How to make that case Insensitive?

Like this:

$Query404=preg_replace('/index\.htm$/i', '', $Query404);

I see.

I suppose

$Query404=preg_replace("'index.htm$'i", '', $Query404);

would work too. Thanks.
