Question

我是一名PHP初学者，遇到以下问题，我完全陷入困境。我有一个这种格式的数组

Array (
  [date] => 0
  [author] => 1
  [categories] => 1
  [tags] => 0
  [comments] => 0
  [readmore] => 0
)

现在我需要从该数组中删除[value] => 0的所有项目并以此格式获取

Array (
  [0] => author
  [1] => categories
)

非常感谢您的任何意见。

Answer 1

使用array_filter然后array_keys：

$array = array ( 'date' => 0, 'author' => 1, 'categories' => 1, 'tags' => 0, 'comments' => 0, 'readmore' => 0 );
$array = array_filter($array);
print_r(array_keys($array));

<强>输出

Array
(
    [0] => author
    [1] => categories
)

Answer 2

那里有一个名为array_search()的函数。假设唯一可能的值是0和1，您可以只搜索整个数组以获取此值：

$array = [
  'date' => 0,
  'author' => 1,
  'categories' => 1,
  'tags' => 0,
  'comments' => 0,
  'readmore' => 0
];
$new_array = array_flip(array_search(1, $array));

因此print_r($new_array)会为您提供所需的结果。

Answer 3

您可以尝试这样的事情：

foreach($array as $item){
 if($item == "0"){
  unset($item);
 }
}

使用unset函数进行一些修改。

Answer 4

这也是做的......

$dataSource = array('data' => 0,
        'author' => 1,
        'categories' => 1,
        'tags' => 0,
        'comments' => 0,
        'readmore' => 0,
    );

$updatedDataList = array();
foreach ($dataSource as $key => $value) {
    if($value !== 0) {
        $updatedDataList[] = $key;
    }
}

print_r($updatedDataList);

Answer 5

您可以尝试以下代码

$yourArray = Array ("date" => 0,"author" => 1, "categories" => 1,"tags" => 0, "comments" => 0,"readmore" => 0 );
$removeZeroFromArray = array(0);
$desiredResult = array_diff($yourArray, $removeZeroFromArray);                          
echo"<pre>";
print_r(array_keys($desiredResult));
echo"</pre>";

您的输出就像

Array
(
    [0] => author
    [1] => categories
)

替代方式应该是

$desiredResult = array_filter($yourArray, function($a) { return ($a !== 0); });

希望它有所帮助！

@savethegold你可以像下面那样保存你的金币：D

{{ Form::model($books, ['route' => ['admin.book.edit', $books->id], 'class' => 'form-horizontal', 'role' => 'form', 'method' => 'PATCH']) }}
<!--form content-->
{{ Form::close() }}

Answer 7

<?php
$array = array ( 'date' => 0, 'author' => 1, 'categories' => 1, 'tags' => 0, 'comments' => 0, 'readmore' => 0 );
$resutl = [];
foreach($array as $k => $v)
{
  if($v != 0)
    $result[] = $k;
}
print_r($result);

删除所有值=＆gt;从数组0并反转它
