The `arsort()` function in PHP is used to sort an associative array in descending order while maintaining the index association.
Syntax
arsort(array &$array, int $flags = SORT_REGULAR): boolExample
<?php
$marks = [
"John" => 85,
"Alice" => 92,
"Bob" => 78,
"David" => 88
];
arsort($marks); // Sort in descending order while maintaining keys
foreach ($marks as $name => $score) {
echo "$name: $score\n";
}
?>
Output
Alice: 92 David: 88 John: 85 Bob: 78
