在数组操作方面需要帮助(php)

Question

我有这个$ record数组

array(4) { 
[0]=> array(2) { ["ROLE_ID"]=> string(1) "2" ["SUBFUNCTION_ID"]=> string(3) "904" } 
[1]=> array(2) { ["ROLE_ID"]=> string(1) "2" ["SUBFUNCTION_ID"]=> string(3) "903" } 
[2]=> array(2) { ["ROLE_ID"]=> string(1) "2" ["SUBFUNCTION_ID"]=> string(3) "902" } 
[3]=> array(2) { ["ROLE_ID"]=> string(1) "2" ["SUBFUNCTION_ID"]=> string(3) "901" } 
} 

我怎么能操纵它所以它会变成这样？

array("901","902","903","904");

$subfunctionIds = array();

foreach($record as $values) {
   $subFunctionIds[] = $values['SUBFUNCTION_ID'];
}

// If you want them reversed like in your example output...
$subFunctionIds = array_reverse($subFunctionIds);

var_dump($subFunctionIds);
