Sort the two-dimensional array and rerank the upper mark

Two-dimensional array sorting, and the subscript re-arranged as the question, I sorted a field, after sorting, found that the subscript also followed, hope that the subscript again, from 0 ~ Start sorting. how can this problem be solved ?, PHPcode $ fruits = array (& quot; d & quot; = & gt; & quot; lemon & quot;, & quot; a & quot; = & sort two-dimensional arrays, and the subscript is re-arranged.
For example, after sorting a field, I found that the subscript also followed. I want to re-rank the subscript from 0 ~ Start sorting. how can this problem be solved?

------ Solution --------------------

PHP code

$ Fruits = array ("d" => "lemon", "a" => "orange", "B" => "banana ", "c" => "apple"); ksort ($ fruits); print"
"; Var_dump ($ fruits );
------ Solution --------------------

   
   

    
    
PHP code
    
    
$ Ar = array ("10", 11,100,100, "a"), array (1, 2, "2", 3, 1 )); array_multisort ($ ar [0], SORT_ASC, SORT_STRING, $ ar [1], SORT_NUMERIC, SORT_DESC); // SORT_ASC, SORT_DESC, SORT_REGULAR, SORT_NUMERIC, SORT_STRINGprint"
"; Print_r ($ ar );

I think you need this --
Check the last parameter of the last code.


Example #4 sort database results


In this example, each unit in the data array represents a row in a table. This is a collection of typical database records.


The data in the example is as follows:


Volume | edition
------- + --------
67 | 2
86 | 1
85 | 6
98 | 2
86 | 6
67 | 7


All data is stored in an array named data. This is usually the result obtained from the database through a loop, such as mysql_fetch_assoc ().



      $ Data [] = array ('Volume '=> 67, 'version' => 2 );
$ Data [] = array ('Volume '=> 86, 'version' => 1 );
$ Data [] = array ('Volume '=> 85, 'version' => 6 );
$ Data [] = array ('Volume '=> 98, 'version' => 2 );
$ Data [] = array ('Volume '=> 86, 'version' => 6 );
$ Data [] = array ('Volume '=> 67, 'version' => 7 );
?>


In this example, we will sort volume in descending order and edition in ascending order.


Now we have an array containing rows, but array_multisort () needs an array containing columns. Therefore, we use the following code to obtain and sort columns.



      // Retrieve the column list
Foreach ($ data as $ key => $ row ){
$ Volume [$ key] = $ row ['Volume '];
$ Edition [$ key] = $ row ['version'];
}

// Sort data by volume in descending order and edition in ascending order
// Use $ data as the last parameter and sort it by a common key
Array_multisort ($ volume, SORT_DESC, $ edition, SORT_ASC, $ data );
?>


The data set is sorted as follows:


Volume | edition
------- + --------
98 | 2
86 | 1
86 | 6
85 | 6
67 | 2
67 | 7



------ Solution --------------------
Set $ t to the sorting result, and the subscript is not in ascending order.
Then $ t = array_values ($ t );
It can be converted into a subscript in ascending order.
