本文实例讲述了PHP中使用PHPExcel读写excel(xls)文件的方法，非常实用。分享给大家供大家参考之用。具体方法如下：

很多PHP类库在读取中文的xls、csv文件时会有问题，网上找了下资料，发现PHPExcel类库好用，官网地址为：http://phpexcel.codeplex.com/。现将PHPExcel读写Excel的方法分别叙述如下：

1、读取xls文件内容

<?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);
    
    $cols = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    //设置www.yx10011.com标题
    for($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");
  }
  $array = array(
    array(1111,"名称","品牌","商品名","//www.yx10011.com"),
    array(1111,"名称","品牌","商品名","//www.yx10011.com"),
    array(1111,"名称","品牌","商品名","//www.yx10011.com"),
    array(1111,"名称","品牌","商品名","//www.yx10011.com"),
    array(1111,"名称","品牌","商品名","//www.yx10011.com"),
  );
  write_xls($array,array("商品id","供应商名称","品牌","商品名","URL"),"report");
  
?>

2、向xls文件写内容

<?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 ?")) {
      $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);
?>
