取消设置元素后重新设置数组键的基数 [英] Rebase array keys after unsetting elements

问题描述

我有一个数组:

$array = array(1,2,3,4,5);

如果我要转储数组的内容，它们将如下所示:

If I were to dump the contents of the array they would look like this:

array(5) {
  [0] => int(1)
  [1] => int(2)
  [2] => int(3)
  [3] => int(4)
  [4] => int(5)
}

当我循环浏览并取消设置某些键时，索引将全部抬起.

When I loop through and unset certain keys, the index gets all jacked up.

foreach($array as $i => $info)
{
  if($info == 1 || $info == 2)
  {
    unset($array[$i]);
  }
}

随后，如果我现在又进行了一次转储，它将看起来像:

Subsequently, if I did another dump now it would look like:

array(3) {
  [2] => int(3)
  [3] => int(4)
  [4] => int(5)
}

是否有适当的方法来重置数组，以便其元素再次基于零?

Is there a proper way to reset the array so it's elements are Zero based again ??

array(3) {
  [0] => int(3)
  [1] => int(4)
  [2] => int(5)
}

推荐答案

尝试一下:

$array = array_values($array);

使用 array_values()
