Re-index numeric array keys
提问by Tower
I have an array that is built using the explode()function, but seeing how i'm using it with random/dynamic data, i see that the indexes keep changing:
我有一个使用该explode()函数构建的数组，但是看到我如何将它与随机/动态数据一起使用，我看到索引不断变化：
Array
(
[2] => Title: Warmly little before cousin sussex entire set Blessing it ladyship.
[3] => Snippet: Testing
[4] => Category: Member
[5] => Tags: little, before, entire
)
I need the array to be ordered starting at 0 always. I am testing with different data and sometimes it starts at 0, and with other tests it begins at different numbers. I researched and came across Array starting at zerobut it seems that only applied to that users specific case. The code i'm using to build the array can be seen here: https://stackoverflow.com/a/10484967/1183323
我需要数组总是从 0 开始排序。我正在用不同的数据进行测试，有时它从 0 开始，而在其他测试中，它从不同的数字开始。我研究并发现Array 从零开始，但似乎只适用于该用户的特定情况。我用来构建数组的代码可以在这里看到：https: //stackoverflow.com/a/10484967/1183323
How can i do this?
我怎样才能做到这一点？

Use array_merge()to renumber the array:
使用array_merge()对数组重新编号：
$your_old_array = array( 2 => 'whatever', 19 => 'huh', 22 => 'yep' );
$your_new_array = array_merge($your_old_array);
print_r($your_new_array);
Prints this:
打印这个：
Array (
[0] => whatever
[1] => huh
[2] => yep )
