從受保護的TXT文件中提取數據並通過PHP將其轉換為表格

Question

我有一些在文本文檔中格式化並用逗號分隔的選舉數據，我正在嘗試使用 PHP 為我們的網站重新格式化。

文本文件受用戶名和密碼保護，因此我試圖弄清楚如何將數據提取到數組中進行操作。 這是鏈接（https://go.elections.hawaii.gov/media-results/files/summary.txt ），但我在此處提取了數據樣本以供參考（ http://lilly-digital.com/test /summary.txt )。

使用下面的代碼，我能夠生成此表，但我需要重新排序並排除一些數據： https://lilly-digital.com/test/parse.php關於如何執行此操作的任何建議？

<?php

$filename = 'https://lilly-digital.com/test/summary.txt';

$the_big_array = []; 

if (($h = fopen("{$filename}", "r")) !== FALSE) 
{
  while (($data = fgetcsv($h, 1000, ",")) !== FALSE) 
  {
    $the_big_array[] = $data;       
  }

  // Close the file
  fclose($h);
}

$build = '<table><tbody>';
foreach($the_big_array as $row)
{
$build .= '<tr>';
foreach($row as $item)
{
$build .= "<td>{$item}</td>";
}
$build .= '</tr>';
}
$build .= '</tbody></table>';
echo $build;

?>

總之，知道如何使用用戶名和密碼提取數據並重新格式化數據嗎？ 我對此比較陌生。

提前致謝。

Answer 1

服務器使用HTTP 基本身份驗證進行保護，因此您需要在請求中傳遞用戶名和密碼。 您可以使用stream_context_create做到這一點

$username='Roland';
$password='Orzabal';

$auth = base64_encode("$username:$password");
$header = array("Authorization: Basic $auth");
$opts = array( 'http' => array ('method'=>'GET', 'header'=>$header));
$ctx = stream_context_create($opts);
//stream context is ready

$filename = 'https://lilly-digital.com/test/summary.txt';

$the_big_array = []; 

stream 上下文是fopen中的最后一個可選參數

if (($h = fopen("{$filename}", "r", false, $context)) !== FALSE) 
{
    //stuff 
}

//other stuff

您可以嘗試以下代碼：

$https_user = "user_name";
$https_password = "password";

$opts = array('http' =>
  array(
    'method'  => 'GET',
    'header'  => "Content-Type: text/xml\r\n".
      "Authorization: Basic ".base64_encode("$https_user:$https_password")."\r\n",
    'content' => $body,
    'timeout' => 60
  )
);

$https_server = 'https://lilly-digital.com/test/summary.txt';
$context  = stream_context_create($opts);
$url = $https_server;
$result = file_get_contents($url, false, $context);

$line_array = explode(PHP_EOL, $result);

$final_result = array_map(function($val) {
    return explode(',', $val);
}, $line_array);

$final_result將代表一個多維數組。 根據需要處理此數組

驗證碼使用來自Ariful Islam的回答

$https_user = "user_name";
$https_password = "password";

$opts = array('http' =>
  array(
    'method'  => 'GET',
    'header'  => "Content-Type: text/xml\r\n".
      "Authorization: Basic ".base64_encode("$https_user:$https_password")."\r\n",
    'content' => $body,
    'timeout' => 60
  )
);

一旦通過身份驗證，您應該嘗試array_combine function 它將創建一個數組，其中的鍵包含字段名，值包含Mysql表的字段數據。 代碼將如下所示：

$fileUrl = 'https://lilly-digital.com/test/summary.txt';
$delimiter=',';
$header = NULL;
$data = array();
if (($handle = fopen($fileUrl, 'r')) !== FALSE){
  while (($row = fgetcsv($handle,0, $delimiter)) !== FALSE)
  {
   if(!$header) 
     $header = $row;
   else 
    $data[] = array_combine($header, $row);
   }
   fclose($handle);
}

output 將類似於以下

Array
(
    [0] => Array
        (
            [Contest ID] => 2
            [Contest Title] => U.S. Representative, Dist I - D
            [Contest Seq Nbr] => 2
            [Contest Type] => OF
            [Contest Party] => 
            [Absentee Mail Blank Votes] => 0
            [Absentee Walk-in Blank Votes] => 0
            [Election Blank Votes] => 0
            [Absentee Mail Over Votes] => 0
            [Absentee Walk-in Over Votes] => 0
            [Election Over Votes] => 0
            [Registered Voters] => 795248
            [Total Precincts] => 115
            [Counted Precincts] => 0
            [Candidate ID] => 9
            [Candidate Name] => CASE, Ed
            [Candidate Seq Nbr] => 1
            [Candidate Party] => 
            [Absentee Mail Votes] => 0
            [Absentee Walk-in Votes] => 0
            [Election Votes] => 0
            [Total Votes] => 0
        )

    [1] => Array ... so on

要插入數據庫，需要使用以下代碼

$fields = implode("','",$header);
$fields = "'".$fields."'";

foreach($data as $key => $value) {

$value = implode("','",$value);
$value = "'".$value."'";

 $sql = "INSERT INTO TABLENAME ($fields) VALUES ($value)";
}

注意：強烈建議使用Mysql Prepared statement 。 您可以在實現時使用上述邏輯。
