PHP Array Array Sort by Field
/**
* Sort array by filed and type, common utility method.
* @param array $data
* @param string $sort_filed
* @param string $sort_type SORT_ASC or SORT_DESC
*/
public function sortByOneField($data, $filed, $type)
{
if (count($data) <= 0) {
return $data;
}
foreach ($data as $key => $value) {
$temp[$key] = $value[$filed];
}
array_multisort($temp, $type, $data);
return $data;
}
The PHP array Array is sorted in two dimensions, first by the first field, then by the second field
/**
* Sort array by filed and type, common utility method.
* @param array $array
* @param string $filed1
* @param string $type1 SORT_ASC or SORT_DESC
* @param string $filed2
* @param string $type2 SORT_ASC or SORT_DESC
*/
public function sortByTwoFiled($data, $filed1, $type1, $filed2, $type2)
{
if (count($data) <= 0) {
return $data;
}
foreach ($data as $key => $value) {
$temp_array1[$key] = $value[$filed1];
$temp_array2[$key] = $value[$filed2];
}
array_multisort($temp_array1, $type1, $temp_array2, $type2, $data);
return $users;
}
sortMultiArray () at most support 3-D array sorting, of course, can be extended, custom method overload to achieve the sorting of multi-dimensional numbers, where the multi-dimensional data is said to be multiple fields.
Usage:
1. sortMultiArray ($data, ['score' = > SORT_DESC])
2. sortMultiArray ($data, ['score' = > SORT_DESC, 'count' = > SORT_ASC])
3. sortMultiArray ($data, ['score' =
>
SORT_DESC, 'count' =
>
SORT_ASC, 'name' =
>
SORT_ASC])
