PHP two-dimensional array is sorted according to a certain field (sorting the query result set)

We often encounter sorting based on a certain key value of a two-dimensional array, and then suddenly think of a function in the onethink project, so we extract it as a reference.

2014-05-22 17::15 After reading the comments from enthusiastic phpers, I added the following:
It is recommended to use PHP’s native array_multisort() function, which will execute faster and reduce the dependence on custom functions
Official documents are difficult to explain Understand, friends who don’t understand can use

 $refer = $resultSet = array();
 foreach ($list as $i => $data)
 {
 $refer[$i] = &$data[$field];
 }
 switch ($sortby)
 {
 case 'asc': // Forward sorting
 asort($refer);
 break;
 case 'desc': // Reverse sorting
 arsort($refer);
 break;
 case 'nat': // Natural sorting
 natcasesort($refer);
 break;
 }
 foreach ($refer as $key => $val)
 {
 $resultSet[] = &$list[$key] ;
 }
 return $resultSet;
 }
 return false;
 }

/**
 * Example
 * Asking: Sort in descending order according to the id key value of the two-dimensional array (that is, the larger the id is, the higher it is)?
*/
$list = array(
 0 => array(
 'id' => 1,
 'name' => 'first'
 ),
 1 => array(
 'id' => 3,
 'name' => 'third'
 ),
 2 => array(
 'id' => 2,
 'name' => ; 'Second'
 ),
 3 => array(
 'id' => 4,
 'name' => 'Fourth'
 ),
);
//Answer
$new_list = list_sort_by ($list, 'id', 'desc');
