Many PHP libraries have problems when reading Chinese xls and csv files. I searched for information online and found that the PHPExcel class library is easy to use. The official website address is: http://phpexcel.codeplex.com/. The methods of reading and writing Excel with PHPExcel are now described as follows:

1. Read xls file content

<&#63;php
  //向xls文件写入内容
  error_reporting(E_ALL);
  ini_set('display_errors', TRUE);  
  include 'Classes/PHPExcel.php';      
  include 'Classes/PHPExcel/IOFactory.php'; 
  //$data:xls文件内容正文
  //$title:xls文件内容标题
  //$filename:导出的文件名
  //$data和$title必须为utf-8码，否则会写入FALSE值
  function write_xls($data=array(), $title=array(), $filename='report'){
    $objPHPExcel = new PHPExcel();
    //设置文档属性，设置中文会产生乱码，需要转换成utf-8格式！！
    // $objPHPExcel->getProperties()->setCreator("云舒")
               // ->setLastModifiedBy("云舒")
               // ->setTitle("产品URL导出")
               // ->setSubject("产品URL导出")
               // ->setDescription("产品URL导出")
               // ->setKeywords("产品URL导出");
    $objPHPExcel->setActiveSheetIndex(0);
    
    $cols = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
    //设置www.jb51.net标题
    for($i=0,$length=count($title); $i<$length; $i++) {
      //echo $cols{$i}.'1';
      $objPHPExcel->getActiveSheet()->setCellValue($cols{$i}.'1', $title[$i]);
    }
    //设置标题样式
    $titleCount = count($title);
    $r = $cols{0}.'1';
    $c = $cols{$titleCount}.'1';
    $objPHPExcel->getActiveSheet()->getStyle("$r:$c")->applyFromArray(
      array(
        'font'  => array(
          'bold'   => true
        ),
        'alignment' => array(
          'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_RIGHT,
        ),
        'borders' => array(
          'top'   => array(
            'style' => PHPExcel_Style_Border::BORDER_THIN
          )
        ),
        'fill' => array(
          'type'    => PHPExcel_Style_Fill::FILL_GRADIENT_LINEAR,
          'rotation'  => 90,
          'startcolor' => array(
            'argb' => 'FFA0A0A0'
          ),
          'endcolor'  => array(
            'argb' => 'FFFFFFFF'
          )
        )
      )
    );
    
    $i = 0;
    foreach($data as $d) { //这里用foreach,支持关联数组和数字索引数组
      $j = 0;
      foreach($d as $v) {  //这里用foreach,支持关联数组和数字索引数组
        $objPHPExcel->getActiveSheet()->setCellValue($cols{$j}.($i+2), $v);
        $j++;
      }
　　　　　　　$i++;
    }
    // 生成2003excel格式的xls文件
    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="'.$filename.'.xls"');
    header('Cache-Control: max-age=0');

    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
    $objWriter->save('php://output');
  }
  $array = array(
    array(1111,'名称','品牌','商品名','http://www.bkjia.com'),
    array(1111,'名称','品牌','商品名','http://www.bkjia.com'),
    array(1111,'名称','品牌','商品名','http://www.bkjia.com'),
    array(1111,'名称','品牌','商品名','http://www.bkjia.com'),
    array(1111,'名称','品牌','商品名','http://www.bkjia.com'),
  );
  write_xls($array,array('商品id','供应商名称','品牌','商品名','URL'),'report');

2. Write content to xls file

<&#63;php
  //获取数据库数据(mysqli预处理学习)
  $config = array(
    'DB_TYPE'=>'mysql',
    'DB_HOST'=>'localhost',
    'DB_NAME'=>'test',
    'DB_USER'=>'root',
    'DB_PWD'=>'root',
    'DB_PORT'=>'3306',
  );
  function getProductIdByName($name) {
    global $config;
    $id = false;
    
    $mysqli = new mysqli($config['DB_HOST'], $config['DB_USER'], $config['DB_PWD'], $config['DB_NAME']);
    if(mysqli_connect_error()) {  //兼容 < php5.2.9 OO way:$mysqli->connect_error
      die("连接失败，错误码：".mysqli_connect_errno()."错误信息：".mysqli_connect_error());
    }
    //设置连接数据库的编码，不要忘了设置
    $mysqli->set_charset("gbk");
    //中文字符的编码要与数据库一致，若没设置，结果为null
    $name = iconv("utf-8", "gbk//IGNORE", $name);
    if($mysqli_stmt = $mysqli->prepare("select id from 137_product where name like &#63;")) {
      $mysqli_stmt->bind_param("s", $name);
      $mysqli_stmt->execute();
      $mysqli_stmt->bind_result($id);
      $mysqli_stmt->fetch();
      $mysqli_stmt->close();
    }
    $mysqli->close(); 
    return $id;  //得到的是gbk码（同数据库编码）
  }  
  $id = getProductIdByName('%伊奈卫浴伊奈分体座便器%');
  var_dump($id);
