php添加excel更新数据表数据

大佬教程收集整理的这篇文章主要介绍了php添加excel更新数据表数据，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

公司有个需求，是用excel更新数据的，把错误的行列放到一个数组返回出来，正常的数据则插入，且返回数量

1.先需要引入PHPspreadsheet，这里使用COR_159_11845@poser 安装

composer require PHPoffice/PHPspreadsheet

2.还需要在头部引入，命名空间自己根据vendor目录设置

use Exception;
use PHPOffice\PHPSpreadsheet\Cell\Coordinate;
use PHPOffice\PHPSpreadsheet\Reader\XLSX;
use PHPOffice\PHPSpreadsheet\Reader\Xls;
use PHPOffice\PHPSpreadsheet\Reader\Csv;

3.下面就是相关代码了，其实逻辑很简单，把excel导入的数据和数据表的字段拼接成二维数组，然后插入就行了

  /**
   * excel开启@L_801_15@
   * author: panzhide
   * @return array
   * Date: 2020/9/4
   */
  public function logisticsImportExcel()
  {
    $file = request()->file('file');
    if (!$filE) {
      return json_success('excel文件不能为空', 'file');
    }
    //将文件保存到public/storage/uploads/目录下面
    $savename = \think\Facade\Filesystem::disk('public')->putFile('uploads', $filE);

    //获取文件路径
    $filePath = getcwd() . '/storage/' . $savename;
    if (!is_file($filePath)) {
      return json_success('没有发现结果');
    }
    //实例化reader
    $ext = pathinfo($filePath, PATHINFO_EXTENSION);
    if (!in_array($ext, ['csv', 'xls', 'xLSX'])) {
      return json_success('未知的数据格式');
    }
    if ($ext === 'csv') {
      $file = fopen($filePath, 'r');
      $filePath = tempnam(sys_get_temp_dir(), 'import_csv');
      $fp = fopen($filePath, "w");
      $n = 0;
      while ($line = fgets($filE)) {
        $line = rtrim($line, "\n\r\0");
        $encoding = mb_detect_encoding($line, ['utf-8', 'gbk', 'latin1', 'big5']);
        if ($encoding != 'utf-8') {
          $line = mb_convert_encoding($line, 'utf-8', $encoding);
        }
        if ($n == 0 || preg_match('/^".*"$/', $linE)) {
          fwrite($fp, $line . "\n");
        } else {
          fwrite($fp, '"' . str_replace(['"', ','], ['""', '","'], $linE) . "\"\n");
        }
        $n++;
      }
      fclose($filE) || fclose($fp);

      $reader = new Csv();
    } elseif ($ext === 'xls') {
      $reader = new Xls();
    } else {
      $reader = new XLSX();
    }

    //导入文件首行类型,默认是注释,如果需要使用字段名称请使用Name
    $importHeadType = isset($this->importHeadTypE) ? $this->importHeadType : 'comment';
    //默认的表名
    $table = OrderAddress::build()->getTable();

    $fieldArr = [];
    $list = Db::query('SHOW FULL columNS FROM `' . $table . '`');
    foreach ($list as $k => $v) {
      if ($importHeadType == 'comment') {
