Question

我有两个文件，一个是制表符分隔的，一个是逗号分隔的csv，它们都上传了，我需要将它们组合成一个有序的csv ...这里是我的代码到目前为止

$txt = glob('files/*.txt*');
$csv = glob('files/*.csv*');
$test = array();
if (($handle = fopen($csv[0], "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $num = count($data);
        $row++;
        for ($c=0; $c < $num; $c++) {
            $test[$c][] = $data[$c];
        }
    }
    fclose($handle);
}

if (($handle = fopen($txt[0], "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, "\t")) !== FALSE) {
        $num = count($data);
        $row++;
        for ($c=0; $c < $num; $c++) {
          $test[$c][] = $data[$c];
        }
    }
    fclose($handle);
}

测试数组有两个完整的数组但是我遇到了一些问题首先$ test数组是这样的

[0] => Array
       (
           [0] => Edit
           [1] => y
           [2] => y
           [3] => y
           [4] => y
           [5] => y
           [6] => y
           [7] => y
           [8] => y
           [9] => y
[1] => Array
    (
        [0] => Event
        [1] => Carolina Panthers PSL
        [2] => Florida
        [3] => Carolina Panthers PSL
        [4] => Apple
        [5] => Carolina Panthers PSL
        [6] => Carolina Panthers PSL
        [7] => Carolina Panthers PSL
        [8] => Carolina Panthers PSL
        [9] => Carolina Panthers PSL
        [10] => Carolina Panthers PSL
[2] => Array
     (
         [0] => Venue
         [1] => Bank of America Stadium 
         [2] => Washington Mutual 
         [3] => Bank of America Stadium 
         [4] => Apple Inc
         [5] => Bank of America Stadium 
         [6] => Bank of America Stadium 
         [7] => Bank of America Stadium 
         [8] => Bank of America Stadium 
         [9] => Bank of America Stadium 
         [10] => Bank of America Stadium 
         [11] => Bank of America Stadium 
         [12] => Bank of America Stadium

我如何使用所有内容创建一个新的csv，但我需要按事件名称进行排序，这个测试数组的格式似乎没有了......任何想法我做错了...

Answer 1

假设列名在文件的第一行，这应该有效：

$txt = glob('files/*.txt*');
$csv = glob('files/*.csv*');
$test = array();
$headers = array();
if (($handle = fopen($csv[0], "r")) !== FALSE) {
  while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $num = count($data);
    if (empty($headers)) {
      for ($c=0; $c < $num; $c++) {
        $headers[$c] = $data[$c];
      }
    }
    else {
      $line = array();
      for ($c = 0; $c < $num; $c++) {
        $line[$headers[$c]] = $data[$c];
      }
      $test[] = $line;
    }
  }
}

if (($handle = fopen($csv[0], "r")) !== FALSE) {
  while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $num = count($data);
    $line = array();
    for ($c = 0; $c < $num; $c++) {
      $line[$headers[$c]] = $data[$c];
    }
    $test[] = $line;
  }
}

那应该给你一个像

这样的数组

[0] => Array
(
       [Edit] => y
       [Event] => Carolina Panthers PSL
       [Venue] => Bank of America Stadium,
       ...
[1] => Array
(

       [Edit] => y
       [Event] => Florida
       [Venue] => Washington Mutual ,
...

然后，您可以在阵列上使用usort，使用自定义回调按Event键对其进行排序。有关示例的负载，请参阅该函数的文档页面，或者尝试：

function my_sort($a, $b) {
  return strcmp($a['Event'], $b['Event']);
}
usort($test, 'my_sort');

以下代码中的某些内容应该对您有用。我相信。

<?php
// Opens files
$file1 = glob("files/*.txt");
$file1 = $file1[0];
$f1 = file("files/$file1");
$file2 = glob("files/*.csv");
$file2 = $file2[0];
$f2 = file("files/$file2");

// Creates counter and storage arrays for each column
$c = 0;
$col1 = array();
$col2 = array();
$col3 = array();

// goes through each of the first files lines
foreach ($f1 as $row => $data)
{
    // changes tabs for commas
    $data .= str_replace("\t",",",$data);
    // splits the string into the 3 columns in different arrays
    list($col1[$c],$col2[$c],$col3[$c]) = explode(",",$data);
    $c++;
}

foreach ($f2 as $row2 => $data2)
{
    if ($row2 != 0)
    {
        // splits the string into the 3 columns in different arrays
        list($col1[$c],$col2[$c],$col3[$c]) = explode(",",$data2);
        $c++;
    }
}
// Sort by column 2, the event
asort($col2);

// First column is headers
$realOutput = $col1[0].",".$col2[0].",".$col3[0]."\n";

// Add them in sorted order by column 2
foreach ($col2 as $key => $val)
{
    if ($key != 0)
        $realOutput .= $col1[$key].",".$col2[$key].",".$col3[$key]."\n";
}

echo $realOutput;

?>

已编辑以考虑不在同一订单中的列，并避免在已排序的数据中出现列标题。这仍然依赖于列标题相同（包括相同的情况）。同样已修复SORTDESC（应为SORT_DESC）

$txt = glob('files/*.txt*');
$csv = glob('files/*.csv*');
$rows = $events = array();

// Get data into rows, not columns
if (($handle = fopen($csv[0], "r")) !== FALSE) {
    // Get column headers
    $headers = fgetcsv($handle, 1000, ",");
    // Get rest of rows
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $row = array();
        foreach ($data as $k => $v) $row[$headers[$k]] = $v;
        $rows[] = $row;
    }
    fclose($handle);
}

if (($handle = fopen($txt[0], "r")) !== FALSE) {
    // Get column headers
    $headers = fgetcsv($handle, 1000, "\t");
    while (($data = fgetcsv($handle, 1000, "\t")) !== FALSE) {
        $row = array();
        foreach ($data as $k => $v) $row[$headers[$k]] = $v;
        $rows[] = $row;
    }
    fclose($handle);
}

// Prepare the sort column for array_multisort()
foreach ($rows as $key => $row) {
  $events[$key] = $row['Event'];
}

// Sort it
array_multisort($events, SORT_DESC, $rows);

// Open the output file
$outFile = fopen('outfile.csv','w');

// Put the column headers back
fputcsv($outFile, array('Edit','Event','Venue'), ',');

// Write the data
foreach ($rows as $row) {
  fputcsv($outFile, $row, ',');
}

// Close the file
fclose($outFile);
