eliminate all null values in array?

[Anon]

is there a function that eliminates all the null values in an array. for example, say I have the following:

Array ( [1] => [2] => [3] => 7 [4] => [5] => [6] => 9 [7] => [8] => [9] => 7 [10] => 4 )

I want to reduce it to:

Array ( [3] => 7 [6] => 9 [9] => 7 [10] => 4 )

I've read the manual and can't seem to find it, but I'm sure it is there. It isn't array_unique, because that would eliminate [9] => 7 from the second array above.

any help?

let $array equal the array to eliminate the nulls

reset($array);
while(list($k,$v)=each($array)){
if(!$v){unset($array[$k]);}
}

hope this helps,
