Question

我得到的数组类似于以下数组。

{"form_data":["1","2","4","5","","6"],"final_data":["1","2","4","5","","6"]}

如果表单数据值为null，我想将该键的值替换为下一个键的值。如上所述，在值5之后，我有空值。它必须是这样的：

"final_data":["1","2","4","5","fill this with 6","remove this"]
"final_data":["1","2","4","5","6"] like this

我尝试array_filter()，但它没有帮助。

Answer 1

如果响应是json格式，那么......

$json = '{"form_data":["1","2","4","5","","6"],"final_data":["1","2","4","5","","6"]}';
$array = json_decode($json, TRUE);

foreach($array as $index => $a) {
  $array[$index] = array_filter($a);
}

print_r($array);

更新：

foreach($array as $index => $a) {
  $array[$index] = array_value(array_filter($a));
}

Answer 2

尝试以下代码，

foreach($myarray as $key=>$value)
{
    if(is_null($value) || $value == '')
        unset($myarray[$key]);
}

Answer 3

使用array_filter()和array_map()

尝试此array_values()

<?php
    $array = array("form_data" => array("1","2","4","5","","6"), "final_data" => array("1","2","4","5","","6"));
    function filterMe($paraArr){
        return array_values(array_filter($paraArr));
    }
    $array = array_map("filterMe",$array);
    echo "<pre>";
    print_r($array);
