如何取消设置两个值为零的数组值...

$array1=Array ( [0] => SL [1] => S [2] => M [3] => L [4] => F ) 
$array2=Array ( [0] => 15 [1] => 22 [2] => 35 [3] => 0 [4] => 0 )

始终第一个数组和第二个数组键相同。我想检查第二个数组值是否为空，如果为空，那么我需要从数组

中删除值

我需要输出：

Array ( [0] => SL [1] => S [2] => M  ) 
Array ( [0] => 15 [1] => 22 [2] => 35 )

Answer 1

假设array1的索引对应于array2的索引，你只需要找到$ array2的索引，其值为0.一旦你完成了，只需从两个数组中取消设置给定索引的元素

foreach($array2 as $key=>$value){
    if($value === 0){
        unset($array2[$key]);
        unset($array1[$key]);
    }
}

Answer 2

function removeZeroValues($array) {
    foreach ($array as $key => $value) {
        if ($value === 0) {
            unset($array[$key]);
        }
    }

    return $array;
}

$array1 = array("SL", "S", "M", "L", "F");
$array2 = array(15, 22, 35, 0, 0);

$array1 = removeZeroValues($array1);
$array2 = removeZeroValues($array2);

echo "<pre>";
print_r($array1);
print_r($array2);

Answer 3

您可以使用array_filter，

$array2 = array_filter($array2);
$array1 = array_filter($array1, function($k)use($array2){return isset($array2[$k]);}, ARRAY_FILTER_USE_KEY);

如何使用php取消设置空值的数组？
