如何结合两个csv /tab分隔成一个csv与php

假设列名在文件的第一行，这应该可以工作:

$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;
  }
}

会得到一个像

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

然后您可以使用usort对数组进行排序，通过自定义回调的Event键。请参阅docs页面，了解该函数的大量示例，或者试试这个:

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

我相信下面的代码行应该可以为您工作。

<?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;
?>

EDITED以解释列的顺序不同，并避免在排序数据中出现列标头。这仍然依赖于列标题相同(包括相同的大小写)。也固定SORTDESC(应该是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);
