Bagaimana saya bisa mengakses array dari file lain di php?

Jika Anda memiliki daftar item (daftar nama mobil, misalnya), menyimpan mobil dalam satu variabel dapat terlihat seperti ini

$mobil1 = "Volvo";
$mobil2 = "BMW";
$mobil3 = "Toyota";

Namun, bagaimana jika Anda ingin menelusuri mobil dan menemukan mobil tertentu?

Solusinya adalah membuat array

Sebuah array dapat menampung banyak nilai di bawah satu nama, dan Anda dapat mengakses nilai dengan mengacu pada nomor indeks

Terima kasih yang luar biasa untuk itu. . )

Jadi sekarang saya punya sesuatu yang baru. LOL Maaf, sekali lagi terima kasih atas bantuan Anda

Data yang perlu saya posting adalah ini

array("y" => 6, "label" => "Apple"),
            array("y" => 4, "label" => "Mango"),
            array("y" => 5, "label" => "Orange"),
            array("y" => 7, "label" => "Banana"),
            array("y" => 4, "label" => "Pineapple"),
            array("y" => 6, "label" => "Pears"),
            array("y" => 7, "label" => "Grapes"),
            array("y" => 5, "label" => "Lychee"),
            array("y" => 4, "label" => "Jackfruit")

Dalam format itu, yang muncul adalah ini

array:9 [▼
  0 => array:2 [▼
    "y" => 6
    "label" => "Apple"
  ]
  1 => array:2 [▼
    "y" => 4
    "label" => "Mango"
  ]
  2 => array:2 [▼
    "y" => 5
    "label" => "Orange"
  ]
  3 => array:2 [▼
    "y" => 7
    "label" => "Banana"
  ]
  4 => array:2 [▼
    "y" => 4
    "label" => "Pineapple"
  ]
  5 => array:2 [▶]
  6 => array:2 [▶]
  7 => array:2 [▶]
  8 => array:2 [▶]
]

Itu hanya mencetaknya di file/halaman template saya

Javascript yang saya gunakan adalah ini

Saya berharap data akan diposting sebagai $dataPoints

The format of this array is (assuming your form has two input type=file fields named "file1", "file2", etc):

Array
(
    [file1] => Array
        (
            [name] => MyFile.txt (comes from the browser, so treat as tainted)
            [type] => text/plain  (not sure where it gets this from - assume the browser, so treat as tainted)
            [tmp_name] => /tmp/php/php1h4j1o (could be anywhere on your system, depending on your config settings, but the user has no control, so this isn't tainted)
            [error] => UPLOAD_ERR_OK  (= 0)
            [size] => 123   (the size in bytes)
        )_

    [file2] => Array
        (
            [name] => MyFile.jpg
            [type] => image/jpeg
            [tmp_name] => /tmp/php/php6hst32
            [error] => UPLOAD_ERR_OK
            [size] => 98174
        )
)

Last I checked (a while ago now admittedly), if you use array parameters in your forms (that is, form names ending in square brackets, like several file fields called "download[file1]", "download[file2]" etc), then the array format becomes.. interesting._

Array
(
    [download] => Array
        (
            [name] => Array
                (
                    [file1] => MyFile.txt
                    [file2] => MyFile.jpg
                )

            [type] => Array
                (
                    [file1] => text/plain
                    [file2] => image/jpeg
                )_

            [tmp_name] => Array
                (
                    [file1] => /tmp/php/php1h4j1o
                    [file2] => /tmp/php/php6hst32
                )_

            [error] => Array
                (
                    [file1] => UPLOAD_ERR_OK
                    [file2] => UPLOAD_ERR_OK
                )

            [size] => Array
                (
                    [file1] => 123
                    [file2] => 98174
                )
        )
)

So you'd need to access the error param of file1 as, eg $_Files['download']['error']['file1']

As of PHP 5.6 the file(), file_get_contents(), and fopen() functions will return false if you are referencing a source URL that doesn't have a valid SSL certificate. Presumably, you will run into this a lot in your development environments this will drive you crazy.

You will need to create a stream context and provide it as an argument to the various file operations to tell it to ignore invalid SSL credentials.

$args = array("ssl"=>array("verify_peer"=>false,"verify_peer_name"=>false),"http"=>array('timeout' => 60, 'user_agent' => 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.9) Gecko/20071025 Firefox/3.0.0.1'));

$context = stream_context_create($args);
$httpfile = file($url, false, $context);
