你如何在PHP中重新索引数组？

$array = array('a' => 'apple', 'b' => 'banana', 'c' => 'cherry');
$new_array = array_values($array);
print_r($new_array);

Array
(
    [0] => apple
    [1] => banana
    [2] => cherry
)

$array = array('a' => 'apple', 'b' => 'banana', 'c' => 'cherry');
$keys = range(0, count($array) - 1);
$new_array = array_combine($keys, $array);
print_r($new_array);

Array
(
    [0] => apple
    [1] => banana
    [2] => cherry
)

$array = array('a' => 'apple', 'b' => 'banana', 'c' => 'cherry');
$new_array = array();
foreach ($array as $value) {
    $new_array[] = $value;
}
print_r($new_array);

Array
(
    [0] => apple
    [1] => banana
    [2] => cherry
)
