preg_match() Pattern Help Needed

I am having trouble with regex and matching a string that DOESN'T contain a sub-string.

Here is an example:
From the list of jpeg files below I want to match only the files that DON'T contain the '.foo' sub-string.

blah_blahblah.foo.jpg
blahblah_blah.jpg

I have tried petterns such as:
/.[^(foo)]/
/.[^(foo)].jpg/
/.*[^(.foo)].jpg/
/[^foo].jpg/

and none of them work as I think they should.

Anyone have any suggestions?

seems like overkill to use preg_match when strpos will do

$ar = array("blah_blahblah.foo.jpg ",
            "blahblah_blah.jpg ",
            "bfoo2.jpg");

$good = array();
foreach($ar as $a) {
   if(strpos($a,"foo") === false) {
      $good[] = $a;
   }
}
print_r($good);
// returns Array ( [0] => blahblah_blah.jpg )

As LordShryku said, if you are only trying to see if one string is contained in another, one should use strpos, as it is faster. But, to show how it could be done:

if (!preg_match("/\\.foo/", $str)) {
