If construct for multiple expressions

I'm working on something like this:

if ($varA != null & $varB = null){
     $newthing = "Something else";
}

It doesn't seem to want to work. I've tried && for & but I can find a good reference for these and what they do.

EDIT: Going to try and clear up what my objective is.

I have three if statement that I want to execute whether or not some variables have value in an encoded URL. Those three statement are:

    if ($lprice != null && $hprice == null){
        $clauses[] = "MSTLISTPRC  >= " . $lprice;
    }
    if ($hprice != null && $lprice == null)(
        $clauses[] = "MSTLISTPRC  <= " . $hprice;
    } 
    if ($lprice != null && $hprice != null){
        $clauses[] = "MSTLISTPRC BETWEEN " . $lprice . " AND " . $hprice;
    }

The final if statement works, the first two don't. It's something with the PHP code itself because I'm testing it an echo to just output the query string and when I try to execute this, it fails. I don't know how to apply error handling so I haven't been using that.

if ($varA != null && $varB = null){
 $newthing = "Something else";
}

You need to use && instead of & and == instead of =.

So:

if ($varA != null && $varB == null){
     $newthing = "Something else";
}
