Which is faster: in_array() or a bunch of expressions in PHP?

if-statement

Is it faster to do the following:

 if ($var != 'test1' && $var != 'test2' && $var != 'test3' && $var != 'test4') { ... }

Or:

 if (!in_array($var, array('test1', 'test2', 'test3', 'test4') { ... }

Is there a number of values at which point it's faster to do one or the other?

(In this case, the array used in the second option doesn't alreay exist.)
