What is the significance of the lack of return value in the asort() function in PHP?

The lack of return value in the asort() function in PHP means that it sorts an array in place and does not return a new sorted array. To work around this, you can use the arsort() function which sorts an array in descending order and maintains key-value associations, and then assign the sorted array to a new variable.

$originalArray = array("b" => 2, "a" => 1, "c" => 3);
arsort($originalArray);
$sortedArray = $originalArray;

// Now $sortedArray contains the sorted array in descending order
