在 PHPSpreadsheet 导入中跳过第一行

Question

刚刚开始使用 phpspreadsheet。我正在尝试弄清楚如何在上传时跳过 Excel 文件中的标题行。

require '../vendor/autoload.php';
if (pathinfo($_FILES['upexcel']['name'], PATHINFO_EXTENSION) == 'csv') {
  $reader = new \PhpOffice\PhpSpreadsheet\Reader\Csv();
} else {
  $reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx();
}
$spreadsheet = $reader->load($_FILES['upexcel']['tmp_name']);

$worksheet = $spreadsheet->getActiveSheet();
$sql = "INSERT INTO `testCommission` (`One`, `two`, `three`, `four`, `five`, `six`, `seven`) VALUES (?, ?, ?, ?, ?, ?, ?)";
foreach ($worksheet->getRowIterator() as $row) {
  // Fetch data
  $cellIterator = $row->getCellIterator();
  $cellIterator->setIterateOnlyExistingCells(false);
  $data = [];
  foreach ($cellIterator as $cell) {
    $data[] = $cell->getValue();
  }

我可以用上面的脚本做什么来实现这个目标？

您需要检测，当它是第一行时，像这样的二进制变量会有所帮助

<?php
require '../vendor/autoload.php';
if (pathinfo($_FILES['upexcel']['name'], PATHINFO_EXTENSION) == 'csv') {
  $reader = new \PhpOffice\PhpSpreadsheet\Reader\Csv();
} else {
  $reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx();
}
$spreadsheet = $reader->load($_FILES['upexcel']['tmp_name']);

$worksheet = $spreadsheet->getActiveSheet();
$sql = "INSERT INTO `testCommission` (`One`, `two`, `three`, `four`, `five`, `six`, `seven`) VALUES (?, ?, ?, ?, ?, ?, ?)";
$isheader = 0;
foreach ($worksheet->getRowIterator() as $row) {
  // Fetch data
  if($isheader > 0) {
      $cellIterator = $row->getCellIterator();
      $cellIterator->setIterateOnlyExistingCells(false);
      $data = [];
      foreach ($cellIterator as $cell) {
          $data[] = $cell->getValue();
      }
  } else 
  { $isheader = 1; }
}
?>

使用过滤器类。 请参阅文档： https://phpspreadsheet.readthedocs.io/en/latest/topics/reading-files/#reading-only-specific-columns-and-rows-from-a-file-read-filters

不要忘记自动加载：

require_once ( 'vendor/autoload.php' );

创建过滤器：

class FirstRowFilter implements \PhpOffice\PhpSpreadsheet\Reader\IReadFilter
{
    public function readCell($column, $row, $worksheetName = '') {
        //  Return true for rows after first row
        return $row > 0;
    }
}

适用于读者：

$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader("Xlsx");

$filterRow = new FirstRowFilter();

$reader->setReadFilter($filterRow);

加载文件：

$spreadsheet = $reader->load($file);

阅读器只会加载指定行之后的行。

您可以使用迭代器的$key：

require '../vendor/autoload.php';
if (pathinfo($_FILES['upexcel']['name'], PATHINFO_EXTENSION) == 'csv') {
  $reader = new \PhpOffice\PhpSpreadsheet\Reader\Csv();
} else {
  $reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx();
}
$spreadsheet = $reader->load($_FILES['upexcel']['tmp_name']);

$worksheet = $spreadsheet->getActiveSheet();
$sql = "INSERT INTO `testCommission` (`One`, `two`, `three`, `four`, `five`, `six`, `seven`) VALUES (?, ?, ?, ?, ?, ?, ?)";
foreach ($worksheet->getRowIterator() as $key => $row) {
  if ($key > 1) {  // not the first line
    // Fetch data
    $cellIterator = $row->getCellIterator();
    $cellIterator->setIterateOnlyExistingCells(false);
    $data = [];
    foreach ($cellIterator as $cell) {
      $data[] = $cell->getValue();
    }
  }
}
