本篇文章主要介绍PHP使用PHPexcel实现数据的导入与导出操作，感兴趣的朋友参考下，希望对大家有所帮助。

导入数据：

<?php
error_reporting(E_ALL); //开启错误
set_time_limit(0); //脚本不超时
date_default_timezone_set(&#39;Europe/London&#39;); //设置时间
/** Include path **/
set_include_path(get_include_path() . PATH_SEPARATOR . &#39;http://www.jb51.net/../Classes/&#39;);//设置环境变量
/** PHPExcel_IOFactory */
include &#39;PHPExcel/IOFactory.php&#39;;
//$inputFileType = &#39;Excel5&#39;; //这个是读 xls的
 $inputFileType = &#39;Excel2007&#39;;//这个是计xlsx的
//$inputFileName = &#39;./sampleData/example2.xls&#39;;
$inputFileName = &#39;./sampleData/book.xlsx&#39;;
  echo &#39;Loading file &#39;,pathinfo($inputFileName,PATHINFO_BASENAME),&#39; using IOFactory with a defined reader type of &#39;,$inputFileType,&#39;<br />&#39;;
  $objReader = PHPExcel_IOFactory::createReader($inputFileType);
  $objPHPExcel = $objReader->load($inputFileName);
  /*
  $sheet = $objPHPExcel->getSheet(0);
  $highestRow = $sheet->getHighestRow(); //取得总行数
  $highestColumn = $sheet->getHighestColumn(); //取得总列
  */ 
  $objWorksheet = $objPHPExcel->getActiveSheet();//取得总行数
  $highestRow = $objWorksheet->getHighestRow();//取得总列数
  echo &#39;highestRow=&#39;.$highestRow;
  echo "<br>";
  $highestColumn = $objWorksheet->getHighestColumn();
  $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);//总列数
  echo &#39;highestColumnIndex=&#39;.$highestColumnIndex;
  echo "<br />";
  $headtitle=array();
  for ($row = 1;$row <= $highestRow;$row++)
  {
   $strs=array();
   //注意highestColumnIndex的列数索引从0开始
   for ($col = 0;$col < $highestColumnIndex;$col++)
   {
    $strs[$col] =$objWorksheet->getCellByColumnAndRow($col, $row)->getValue();
   }
    $info = array(
     &#39;word1&#39;=>"$strs[0]",
     &#39;word2&#39;=>"$strs[1]",
     &#39;word3&#39;=>"$strs[2]",
     &#39;word4&#39;=>"$strs[3]",
    );
    //在这儿，你可以连接，你的数据库，写入数据库了
    print_r($info);
    echo &#39;<br />&#39;;
  }
?>

导出数据：

private function _export_data($data = array())
{
 error_reporting(E_ALL); //开启错误
 set_time_limit(0); //脚本不超时
 date_default_timezone_set(&#39;Europe/London&#39;); //设置时间
 /** Include path **/
 set_include_path(FCPATH.APPPATH.&#39;/libraries/Classes/&#39;);//设置环境变量
 // Create new PHPExcel object
 Include &#39;PHPExcel.php&#39;;
 $objPHPExcel = new PHPExcel();
 // Set document properties
 $objPHPExcel->getProperties()->setCreator("Maarten Balliauw")
    ->setLastModifiedBy("Maarten Balliauw")
    ->setTitle("Office 2007 XLSX Test Document")
    ->setSubject("Office 2007 XLSX Test Document")
    ->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.")
    ->setKeywords("office 2007 openxml php")
    ->setCategory("Test result file");
 // Add some data
 $letter = array(&#39;A&#39;,&#39;B&#39;,&#39;C&#39;,&#39;D&#39;,&#39;E&#39;,&#39;F&#39;,&#39;G&#39;,&#39;H&#39;,&#39;I&#39;,&#39;J&#39;,&#39;K&#39;,&#39;L&#39;,&#39;M&#39;,&#39;N&#39;,&#39;O&#39;,&#39;P&#39;,&#39;Q&#39;,&#39;R&#39;,&#39;S&#39;,&#39;T&#39;,&#39;U&#39;,&#39;V&#39;,&#39;W&#39;,&#39;X&#39;,&#39;Y&#39;,&#39;Z&#39;);    
 if($data){
  $i = 1;
  foreach ($data as $key => $value) {
  $newobj = $objPHPExcel->setActiveSheetIndex(0);
  $j = 0; 
  foreach ($value as $k => $val) {
   $index = $letter[$j]."$i";
   $objPHPExcel->setActiveSheetIndex(0)->setCellValue($index, $val);
   $j++;
  }
   $i++;
  }
 }   
 $date = date(&#39;Y-m-d&#39;,time());  
 // Rename worksheet
 $objPHPExcel->getActiveSheet()->setTitle($date);
 $objPHPExcel->setActiveSheetIndex(0);
 // Redirect output to a client&#39;s web browser (Excel2007)
 header(&#39;Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet&#39;);
 header(&#39;Content-Disposition: attachment;filename="&#39;.$date.&#39;.xlsx"&#39;);
 header(&#39;Cache-Control: max-age=0&#39;);
 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, &#39;Excel2007&#39;);
 $objWriter->save(&#39;php://output&#39;);
 exit;
}

直接上代码：

public function export_data($data = array())
{
 # code...
 include_once(APP_PATH.&#39;Tools/PHPExcel/Classes/PHPExcel/Writer/IWriter.php&#39;) ;
 include_once(APP_PATH.&#39;Tools/PHPExcel/Classes/PHPExcel/Writer/Excel5.php&#39;) ;
 include_once(APP_PATH.&#39;Tools/PHPExcel/Classes/PHPExcel.php&#39;) ;
 include_once(APP_PATH.&#39;Tools/PHPExcel/Classes/PHPExcel/IOFactory.php&#39;) ;
 $obj_phpexcel = new PHPExcel();
 $obj_phpexcel->getActiveSheet()->setCellValue(&#39;a1&#39;,&#39;Key&#39;);
 $obj_phpexcel->getActiveSheet()->setCellValue(&#39;b1&#39;,&#39;Value&#39;); 
 if($data){
  $i =2;
  foreach ($data as $key => $value) {
  # code...
  $obj_phpexcel->getActiveSheet()->setCellValue(&#39;a&#39;.$i,$value);
  $i++;
  }
 } 
 $obj_Writer = PHPExcel_IOFactory::createWriter($obj_phpexcel,&#39;Excel5&#39;);
 $filename = "outexcel.xls";
 header("Content-Type: application/force-download"); 
 header("Content-Type: application/octet-stream"); 
 header("Content-Type: application/download"); 
 header(&#39;Content-Disposition:inline;filename="&#39;.$filename.&#39;"&#39;); 
 header("Content-Transfer-Encoding: binary"); 
 header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); 
 header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
 header("Pragma: no-cache"); 
 $obj_Writer->save(&#39;php://output&#39;); 
}
