试试这个:

$array = array_values($array);

使用元素()

使用array_splice而不是unset:

$array = array(1,2,3,4,5);
foreach($array as $i => $info)
{
  if($info == 1 || $info == 2)
  {
    array_splice($array, $i, 1);
  }
}

print_r($array);

这里是工作样本。

或者，您可以创建自己的函数，通过引用传递数组。

function array_unset($unsets, &$array) {
  foreach ($array as $key => $value) {
    foreach ($unsets as $unset) {
      if ($value == $unset) {
        unset($array[$key]);
        break;
      }
    }
  }
  $array = array_values($array);
}

所以你要做的就是…

$unsets = array(1,2);
array_unset($unsets, $array);

．.． 现在你的$数组没有你在$unsets中放置的值，键被重置

只是一个加法。

我知道这很老了，但我想补充一个我自己没有想到的解决方案。在寻找不同的解决方案时发现了这个问题，然后就想:“好吧，既然我在这里。”

First of all, Neal's answer is good and great to use after you run your loop, however, I'd prefer do all work at once. Of course, in my specific case I had to do more work than this simple example here, but the method still applies. I saw where a couple others suggested foreach loops, however, this still leaves you with after work due to the nature of the beast. Normally I suggest simpler things like foreach, however, in this case, it's best to remember good old fashioned for loop logic. Simply use i! To maintain appropriate index, just subtract from i after each removal of an Array item.

下面是一个简单的例子:

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

for ($i = 0; $i < count($array); $i++) {
    if($array[$i] == 1 || $array[$i] == 2) {
        array_splice($array, $i, 1);
        $i--;
    }
}

将输出:

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

这可以有许多简单的实现。例如，我的具体情况需要根据多维值保存数组中的最新项。我来告诉你我的意思:

$files = array(
    array(
        'name' => 'example.zip',
        'size' => '100000000',
        'type' => 'application/x-zip-compressed',
        'url' => '28188b90db990f5c5f75eb960a643b96/example.zip',
        'deleteUrl' => 'server/php/?file=example.zip',
        'deleteType' => 'DELETE'
    ),
    array(
        'name' => 'example.zip',
        'size' => '10726556',
        'type' => 'application/x-zip-compressed',
        'url' => '28188b90db990f5c5f75eb960a643b96/example.zip',
        'deleteUrl' => 'server/php/?file=example.zip',
        'deleteType' => 'DELETE'
    ),
    array(
        'name' => 'example.zip',
        'size' => '110726556',
        'type' => 'application/x-zip-compressed',
        'deleteUrl' => 'server/php/?file=example.zip',
        'deleteType' => 'DELETE'
    ),
    array(
        'name' => 'example2.zip',
        'size' => '12356556',
        'type' => 'application/x-zip-compressed',
        'url' => '28188b90db990f5c5f75eb960a643b96/example2.zip',
        'deleteUrl' => 'server/php/?file=example2.zip',
        'deleteType' => 'DELETE'
    )
);

for ($i = 0; $i < count($files); $i++) {
    if ($i > 0) {
        if (is_array($files[$i-1])) {
            if (!key_exists('name', array_diff($files[$i], $files[$i-1]))) {
                if (!key_exists('url', $files[$i]) && key_exists('url', $files[$i-1])) $files[$i]['url'] = $files[$i-1]['url'];
                $i--;
                array_splice($files, $i, 1);
            }
        }
    }
}

将输出:

array(1) {
    [0]=> array(6) {
            ["name"]=> string(11) "example.zip"
            ["size"]=> string(9) "110726556"
            ["type"]=> string(28) "application/x-zip-compressed"
            ["deleteUrl"]=> string(28) "server/php/?file=example.zip"
            ["deleteType"]=> string(6) "DELETE"
            ["url"]=> string(44) "28188b90db990f5c5f75eb960a643b96/example.zip"
        }
    [1]=> array(6) {
            ["name"]=> string(11) "example2.zip"
            ["size"]=> string(9) "12356556"
            ["type"]=> string(28) "application/x-zip-compressed"
            ["deleteUrl"]=> string(28) "server/php/?file=example2.zip"
            ["deleteType"]=> string(6) "DELETE"
            ["url"]=> string(45) "28188b90db990f5c5f75eb960a643b96/example2.zip"
        }
}

如您所见，我在拼接前操作$ I，因为我试图删除前一项，而不是当前项。

还有一个有趣的方法:

$array = array('a', 'b', 'c', 'd'); 
unset($array[2]); 

$array = array_merge($array); 

现在$array键被重置。

晚回答但是，在php5.3之后可以这样;

$array = array(1, 2, 3, 4, 5);
$array = array_values(array_filter($array, function($v) {
    return !($v == 1 || $v == 2);
}));
print_r($array);

在我的情况下，我需要保留数组值的唯一键，所以我只是使用了第二个数组:

$arr1 = array("alpha"=>"bravo","charlie"=>"delta","echo"=>"foxtrot");
unset($arr1);

$arr2 = array();
foreach($arr1 as $key=>$value) $arr2[$key] = $value;
$arr1 = $arr2
unset($arr2);

我使用$arr = array_merge($arr);改变数组的基数。简单明了。

百分百为我工作!在数组中取消设置元素后，您可以使用此方法重新索引数组

$result=array_combine(range(1, count($your_array)), array_values($your_array));
