Question

我有一个像这样的数组

    Array
(
    [sch_name] => example
    [sch_degree] => example
    [sch_field] => example
    [sch_grade] => example
    [sch_from_year] => 2008
    [sch_to_year] => 2008
    [sch_desc] => example
)

＆安培;更像上面的数组，现在当我向它添加另一个数组时，它看起来如下所示

  Array
(
    [0] => Array
        (
            [sch_name] => example
            [sch_degree] => example
            [sch_field] => example
            [sch_grade] => example
            [sch_from_year] => 2008
            [sch_to_year] => 2008
            [sch_desc] => example
        )

    [1] => Array
        (
            [sch_name] => example
            [sch_degree] => example
            [sch_field] => example
            [sch_grade] => example
            [sch_from_year] => 2008
            [sch_to_year] => 2008
            [sch_desc] => example
        )

)

现在问题是第三个数组被附加到[1]数组，如下所示

Array
(
    [0] => Array
        (
            [sch_name] => example
            [sch_degree] => example
            [sch_field] => example
            [sch_grade] => example
            [sch_from_year] => 2008
            [sch_to_year] => 2008
            [sch_desc] => example
        )

    [1] => Array
        (
            [0] => Array
                (
                    [sch_name] => example
                    [sch_degree] => example
                    [sch_field] => example
                    [sch_grade] => example
                    [sch_from_year] => 2008
                    [sch_to_year] => 2008
                    [sch_desc] => example
                )

            [1] => Array
                (
                    [sch_name] => example
                    [sch_degree] => example
                    [sch_field] => example
                    [sch_grade] => example
                    [sch_from_year] => 2008
                    [sch_to_year] => 2008
                    [sch_desc] => example
                )

        )

)

我想将新数组附加为[2]＆amp;如果添加更多数组，那么它应该像这样[3]

这是我怎么做的

$post = array();
$post['sch_name'] = test_input($sch_name);
$post['sch_degree'] = test_input($sch_degree);
$post['sch_field'] = test_input($sch_field);
$post['sch_grade'] = test_input($sch_grade);
$post['sch_from_year'] = test_input($sch_from_year);
$post['sch_to_year'] = test_input($sch_to_year);
$post['sch_desc'] = test_input($sch_desc);

$newArray = array($post, $array_from_db);

$ array_from_db是从数据库中提取的，如我在问题开头所示

Answer 1

如果要将值附加到数组，只需使用$array[] = $newArray;，这会将新项目添加为最后一项;

$post = array();
$post['sch_name'] = test_input($sch_name);
$post['sch_degree'] = test_input($sch_degree);
$post['sch_field'] = test_input($sch_field);
$post['sch_grade'] = test_input($sch_grade);
$post['sch_from_year'] = test_input($sch_from_year);
$post['sch_to_year'] = test_input($sch_to_year);
$post['sch_desc'] = test_input($sch_desc);

$array_from_db[] = $post;

Answer 2

您只需要一个容器数组来包含db中的所有数组。但

$newArray = array($post, $array_from_db);

这将创建一个新数组，而不是使用容器。

代码：

// declare a container
$container = array();
$post = array();
$post['sch_name'] = test_input($sch_name);
$post['sch_degree'] = test_input($sch_degree);
$post['sch_field'] = test_input($sch_field);
$post['sch_grade'] = test_input($sch_grade);
$post['sch_from_year'] = test_input($sch_from_year);
$post['sch_to_year'] = test_input($sch_to_year);
$post['sch_desc'] = test_input($sch_desc);


// push $post and $array_from_db to the $container
array_push($container,$post,$array_from_db);

顺便说一句，如果你只是想在数组中添加一个新元素，你可以简单地使用它：

$container[] = $myElement;

它保存调用函数（array_push）。

根据我们的讨论，我们处于这个位置，你完全受益了。 discussion-between-frayne-konok-and-sagar-singh，假设您有来自数据库的数组，如下所示：

Online Check，必须检查。

$array_from_db = array(
        array(
            "sch_name" => "example",
            "sch_degree" => "example",
            "sch_field" => "example",
            "sch_grade" => "example",
            "sch_from_year" => "2008",
            "sch_to_year" => "2008",
            "sch_desc" => "example"
        ),
        array(
            "sch_name" => "example",
            "sch_degree" => "example",
            "sch_field" => "example",
            "sch_grade" => "example",
            "sch_from_year" => "2008",
            "sch_to_year" => "2008",
            "sch_desc" => "example"
        )
    );

新帖子：

$post = array();
$post['sch_name'] = "example";
$post['sch_degree'] = "example";
$post['sch_field'] = "example";
$post['sch_grade'] = "example";
$post['sch_from_year'] = "2008";
$post['sch_to_year'] = "2008";
$post['sch_desc'] = "example";

array_push($array_from_db, $post);

print_r($array_from_db);
