PHP multi-dimensional array sort array detailed

This article explains the PHP multidimensional array sorting array.

Array of PHP arrays sorted by field

/** * Sort array by filed and type, Common utility method. * @param array $data * @par Am String $sort _filed* @param string $sort _type sort_asc or Sort_desc */public function Sortbyonefield ($data, $filed, $typ e) {if (count ($data) <= 0) {return $data;} foreach ($data as $key = = $value) {$temp [$key] = $value [$filed];} arr Ay_multisort ($temp, $type, $data); return $data; The array of PHP arrays is sorted by two dimensions, sorted by first field, sorted by second field * Sort array by filed and type, common utility method. * @param array $array * @param string $filed 1 * @param string $type 1 sort_asc or Sort_desc * @param string $filed 2 * @para M string $type 2 Sort_asc or SORT_DESC */Public Function sortbytwofiled ($data, $filed 1, $type 1, $filed 2, $type 2) {if (cou NT ($DATA) <= 0) {return $data;} foreach ($data as $key = = $value) {$temp _array1[$key] = $value [$filed 1]; $temp _ar ray2[$key] = $value [$filed 2]; } array_multisort ($temp _array1, $type 1, $temp _array2, $type 2, $data); return $users; }

Sortmultiarray () supports up to 3-dimensional array ordering, of course, the custom method overload implements the sort of multidimensional numbers, where multidimensional is said to be multiple fields of data.

How to use:

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])/** * SORT multi array by F Iled and type. * @param data $array * @param condition $array */Public Function Sortmultiarray (& $data, $condition) {if (count ($data ) <= 0 | | Empty ($condition)) {return $data;} $dimension = count ($condition); $fileds = Array_keys ($condition); $types = Array_values ($condition); Switch ($dimension) {Case 1: $data = $this->sort1dimension ($data, $fileds [0], $types [0]); Case 2: $data = $this ->sort2dimension ($data, $fileds [0], $types [0], $fileds [1], $types [1]); Break Default: $data = $this->sort3dimension ($data, $fileds [0], $types [0], $fileds [1], $types [1], $fileds [2], $types [2]); Break } return $data; The Public Function sort1dimension (& $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;  } Public Function Sort2dimension (& $data, $filed 1, $type 1, $filed 2, $type 2) {if (count ($data) <= 0) {return $data; } foreach ($data as $key = + $value) {$sort _filed1[$key] = $value [$filed 1]; $sort _filed2[$key] = $value [$filed 2];} AR Ray_multisort ($sort _filed1, $type 1, $sort _filed2, $type 2, $data); return $data; } Public Function Sort3dimension (& $data, $filed 1, $type 1, $filed 2, $type 2, $filed 3, $type 3) {if (count ($data) <= 0 {return $data;} foreach ($data as $key = + $value) {$sort _filed1[$key] = $value [$filed 1]; $sort _filed2[$key] = $val ue[$filed 2]; $sort _filed3[$key] = $value [$filed 3]; } array_multisort ($sort _filed1, $type 1, $sort _filed2, $type 2, $sort _filed3, $type 3, $data); return $data; }
