我的多维数组如下所示：
Array
(
[0] => Array
(
[0] => 2010-12-03
[1] => 0
[2] => Array
(
[0] => Array
(
[0] =>
[1] =>
[2] => 0
[3] =>
[4] =>
)
[1] => Array
(
[0] =>
[1] =>
[2] => 0
[3] =>
[4] =>
)
[2] => Array
(
[0] =>
[1] =>
[2] => 0
[3] =>
[4] =>
)
[3] => Array
(
[0] =>
[1] =>
[2] => 0

)
[4] => Array
(
[0] =>

[2] => 0
[3] =>

)
[5] => Array
(

)

)
[1] => Array

我尝试过array_filter和不同的循环迭代来删除zero/null值，例如
function removeElementWithValue($array, $key, $value) {
foreach($array as $subKey => $subArray) {
if($subArray[$key] == $value) {
unset($array[$subKey]);
}
}
}
但似乎什么都不起作用。任何帮助都将不胜感激！
您需要递归地调用您的remove函数。（为数组中的每个子值调用函数，然后该函数将自动为每个子值等调用自己，直到它无法进一步深入树）。
下面是一个快速生成（未经测试）的函数，它应该删除所有空值（包括数组，如果它们是空的）：
function removeEmptyElements($array) {
foreach ($array as $key => $value){
if (empty($value)) {
unset($array[$key]);
} else if (is_array($value)) {
$array[$key] = removeEmptyElements($value);
}
}
return $array;
}
也许这个答案有点太迟了，但现在是：
$array = array( // array with examples
array('123',' 456', array(123, null)),
array('', null, '123'),
123,
234,
0,
null,
);
$filterEmptyValues = function($val) use (&$filterEmptyValues) {
foreach($val as $key => $value) {
if (!is_array($value)) {
if (!$value) unset($val[$key]);
}
else $val[$key] = call_user_func($filterEmptyValues, $value);
}
return $val;
};
$array = $filterEmptyValues($array) ;
print_r($array);
