Two-dimensional array sorting, and superscript rearrangement

Two-dimensional array sorting, and subscript rearrangement
Title, I sort of a field, row, found subscript also follow, hope Subscript re-arrange, from 0~ start Platoon, ask how to do?

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

PHP Code

$fruits = Array ("d" = "lemon", "a" and "Orange", "b" = "banana", "c" = "apple"), Ksort ($fruits);p rint "
"; Var_dump ($fruits);
------Solution--------------------

   
   

    
    PHP Code
    
    
$ar = Array (Array ("Ten", One, one, 1, "a"), and an array (2, "2", 3, 1)); Array_multisort ($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--
Take a look at the last parameter of the last piece of code


Example #4 Sorting the results of a database


In this example, each cell in the data array represents a row in a table. This is a data 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


The data is all stored in an array named data. This is usually done by looping the results from the database, such as MYSQL_FETCH_ASSOC ().



      $data [] = Array (' volume ' = +, ' edition ' = 2);
$data [] = Array (' volume ' = +, ' edition ' = 1);
$data [] = Array (' volume ' = =, ' edition ' = 6);
$data [] = Array (' volume ' = = 98, ' edition ' = 2);
$data [] = Array (' volume ' = +, ' edition ' = 6);
$data [] = Array (' volume ' = +, ' edition ' = 7);
?>


In this example, the volume is sorted in descending order, and the edition in ascending order.


Now that you have an array with rows, but Array_multisort () requires an array of columns, so use the following code to get the columns and sort them.



      Get a list of columns
foreach ($data as $key = = $row) {
$volume [$key] = $row [' volume '];
$edition [$key] = $row [' Edition '];
}

Sort data in descending order according to volume, in ascending order of edition
The $data as the last parameter, sorted by the Universal key
Array_multisort ($volume, Sort_desc, $edition, SORT_ASC, $data);
?>


The data set is now sorted and the results are as follows:


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



------Solution--------------------
Set $T is the result of a sort, subscript is not ascending
Then $t = Array_values ($t);
It can be converted to subscript ascending.
