我有一个像这样的数组:
[12601] => Array (
['docUpload'] => html dom.txt
)
[12602] => Array (
['docUpload'] => PYTHON AND DJANGO ARE HUGE IN FINTECH.txt
)
[12603] => Array (
['docUpload'] =>
)
如何获得它:
12601 => html dom.txt
12602 => PYTHON AND DJANGO ARE HUGE IN FINTECH.txt
你能帮我吗?

您必须使用foreach()
$final_array = array();
foreach($array as $key=>$val){
$final_array[$key]= $val['docUpload'];
}
输出:-https://3v4l.org/cP0TO和https://3v4l.org/DRjNn
如果子数组索引是动态的,则
$final_array = array();
foreach($array as $key=>$val){
$final_array[$key]= array_values($val)[0];
}
print_r($final_array);
注意:- 使用array_filter()
删除空索引(第一答案第二输出链接)

使用array_column()
获取值,然后将它们与array_combine()
和array_keys()
组合。
$values = array_column($array, 'docUpload');
$newArray = array_combine(array_keys($array), $values);

您可以通过foreach()
步骤:
1)取一个新的空白数组。我们将结果附加到此。
2)如果数组不为空,请在数组上循环foreach
3)使用键值对。密钥是必需数组中的id
。
4)值是一个以键docUpload
作为文档名称的数组。
5)用id
和value
(docUpload
)附加新元素。
6)结果数组将是一维数组。
最终密码:
$arr = [];
$arr[12401] = ['docUpload' => ''];
$arr[12601] = ['docUpload' => 'html dom.txt'];
$arr[12602] = ['docUpload' => 'PYTHON AND DJANGO ARE HUGE IN FINTECH.txt'];
$arr[12603] = ['docUpload' => ''];
$newArr = [];
if (! empty($arr)) {
foreach ($arr as $id => $docArr) {
$newArr[$id] = $docArr['docUpload'];
}
}
echo '<pre>';print_r($newArr);echo '</pre>';
输出:
Array
(
[12401] =>
[12601] => html dom.txt
[12602] => PYTHON AND DJANGO ARE HUGE IN FINTECH.txt
[12603] =>
)

您需要执行以下操作:
foreach ($arrayData as &$value) {
$value = isset($value['docUpload']) ? $value['docUpload'] : '';
}
这将导致以下数组:
[docUpload] => [
[12601] => html dom.txt
[12602] => PYTHON AND DJANGO ARE HUGE IN FINTECH.txt
];
