Return data between two strings

[Anon]

Hi how do I get PHP to return data between two strings. Like this example

$a = "<Blah some other stuff>THE DOG RUNS</BLAH>";

I want to retrieve THE DOG RUNS

THE DOG RUNS can be anything like a wildcard

Hello,

I found this to work:

    if(eregi(""<Blah some other stuff>(.*)</BLAH>", $input_str, $out_str))
    {
            print htmlspecialchars($out[1]) . "<br>\n";
    } 

Hope this works.
