重新排列數組的鍵PHP

Question

我有此數組：

Array 
(
[15] =>  13.1 

[16] =>  Mark one answer 

[19] => You see a car on the hard shoulder of a motorway with a HELP pennant displayed. This means the driver is most likely to be 

[20] => a disabled person first aid trained 

[21] => a foreign visitor 

[22] => a rescue patrol person 

[25] => DES s15, HC r278); 

我如何得到它的鍵值從0排序？ 得到這個：我知道有一個函數，但我的頭被燒燬，排序函數不符合我的需要，因爲他們重新排列值，我需要它們被保存。

Array 
(
[0] => 13.1 

[1] => Mark one answer 

[2] => You see a car on the hard shoulder of a motorway with a HELP pennant displayed. This means the driver is most likely to be 

[3] => a disabled person first aid trained 

[4] => a foreign visitor 

[5] => a rescue patrol person 

[6] => DES s15, HC r278); 

Answer 1

我認爲你正在尋找array_values

$arr = array_values($arr);
