Question

我在php中有数组：

Array
    (
        [id] => 1
        [comp_id] => 1
        [transaction_purpose] => 0
        [source_of_funds] => 1
        [beneficiary_relationship] => 0
        [cus_occupation] => 0
        [cus_id_image_2] => 0
        [cus_id_image_3] => 0
        [ben_id_type] => 0
        [ben_id_number] => 1
    )

如果valie为1，我想只得到数组键=＆gt;值对。

结果数组应为：

Array
    (
        [id] => 1
        [comp_id] => 1
        [source_of_funds] => 1
        [ben_id_number] => 1
    )

我尝试过：

$returnArray = array();
    foreach($mainArray as $r){
        if($r>0){
            array_push($returnArray, $mainArray);
        }
    }

但是，它给了我4次主阵列。有没有办法实现这个目标？感谢..

Answer 1

只需使用array_filter()：

~~$newarray = array_filter($array, function($var) { return ($var === 1); });~~

$newarray = array_filter($array);

Demo

$array = array(
    'id' => 1,
    'comp_id' => 1,
    'transaction_purpose' => 0,
    'source_of_funds' => 1,
    'beneficiary_relationship' => 0,
    'cus_occupation' => 0,
    'cus_id_image_2' => 0,
    'cus_id_image_3' => 0,
    'ben_id_type' => 0,
    'ben_id_number' => 1
);

$newarray = array_filter($array);

print_r($newarray);

Array
(
    [id] => 1
    [comp_id] => 1
    [source_of_funds] => 1
    [ben_id_number] => 1
)

试试这个：

$returnArray = array_filter($result);

您可以查看PHP的array_filter功能以获取更多信息。

那么，你还有什么期望呢？

        array_push($returnArray, $mainArray);

如果您找到一个值> 0的元素，则将整个原始数组推送到新数组，而不仅仅是您刚测试的键/值。

你可能想要：

$newarr = array();
foreach($mainArray as $key => $value) {
   if ($value > 0) {
        $newarr[$key] = $value;
   }
}

从数组php获取set元素
