Array_multisort () sorts two-dimensional arrays http://www.ucantech.net/website promotion
Array $ roughData, which we plan to sort by accurancy.
Array
(
[0] => Array
(
[Username] => 10yl
[Accuracy] = & gt; 0.00
)
[1] => Array
(
[Username] => 11yl
[Accuracy] = & gt; 1.00
)
[2] => Array
(
[Username] => 12yl
[Accuracy] = & gt; 0.00
)
[3] => Array
(
[Username] => 13yl
[Accuracy] = & gt; 1.00
)
)
Method:
(1) extract an array of accuracy columns
Foreach ($ roughData as $ key => $ row ){
$ Usernames [$ key] = $ row ['username'];
$ Accuracy [$ key] = $ row ['accuracy '];
}
(2) sorting
Array_multisort ($ accuracy, SORT_ASC, $ roughData );
When print_r ($ roughData); then we will get a two-dimensional array (fblww-1230) sorted in ascending order by accuracy)
