Sorting an associative array - php

Question

I have an array $array
$array =>
(
['name'] => (
"Ronaldo","Ribery","Bale","Messi"
),
['rank'] => (
2,4,1,3
)
)
Now How can i sort the array DESC using rank field along with the name
Expected output ->
$array =>
(
['name'] => (
"Ribery","Messi","Ronaldo","Bale"
),
['rank'] => (
4,3,2,1
)
)

Answer 1

A valid use for oft-misunderstood array_multisort()
<?php
$array = [
'name' => ["Ronaldo","Ribery","Bale","Messi"],
'rank' => [2,4,1,3]
];
array_multisort(
$array['rank'], SORT_DESC, SORT_NUMERIC,
$array['name'], SORT_ASC, SORT_STRING
);
var_dump($array);
array(2) {
'name' =>
array(4) {
[0] =>
string(6) "Ribery"
[1] =>
string(5) "Messi"
[2] =>
string(7) "Ronaldo"
[3] =>
string(4) "Bale"
}
'rank' =>
array(4) {
[0] =>
int(4)
[1] =>
int(3)
[2] =>
int(2)
[3] =>
int(1)
}
}

Answer 2

Check out this php article also if you want your two arrays to have a relation than you could better write it like this:
array(
array(
name => 'Messi',
rank => 4,
),
etc..
);

Answer 3

Why not change your data structure to be able to work with objects?
class Player {
public $name; // would be better as private and add getters
public $rank;
public function __construct($name, $rank) {
$this->name = $name;
$this->rank = $rank;
}
}
Then fill your array (I'm not familiar with soccer):
$players = [ // or array(...) if you are using older PHP
new Player('Foo', 3),
new Player('Bar', 1),
new Player('FooBar', 2)
];
Then you can use the regular sort:
// or a function name, if using older PHP
usort($players, function (Player $a, Player $b) {
if ($a->rank == $b->rank) {
return 0;
}
return ($a->rank < $b->rank) ? -1 : 1;
});
