在PHP中重新排列数组

$array = array("apple", "banana", "cherry", "date");
shuffle($array);
print_r($array);

$array = array("apple", "banana", "cherry", "date");
$random_key = array_rand($array, 1);
$random_element = $array[$random_key];
echo $random_element;

$array = array("apple", "banana", "cherry", "date");
sort($array);
print_r($array);

$array = array("apple", "banana", "cherry", "date");
rsort($array);
print_r($array);

$array = array("apple", "banana", "cherry", "date");
usort($array, function($a, $b) {
    return strlen($a) - strlen($b);
});
print_r($array);
