1、先下载 https://github.com/PHPOffice/PHPExcel
2、将SDK解压之后的Class文件拷贝到自己的项目。
一、数据导入
/**
* 数据导入
* @param string $file excel文件
* @param string $sheet
* @return string 返回解析数据
* @throws PHPExcel_Exception
* @throws PHPExcel_Reader_Exception
*/
function importExecl($file='', $sheet=0){
$file = iconv("utf-8", "gb2312", $file); //转码
if(empty($file) OR !file_exists($file)) {
die('file not exists!');
}
include(dirname(__FILE__) . '/includes/Classes/PHPExcel.php'); //引入PHP EXCEL类
$objRead = new PHPExcel_Reader_Excel2007(); //建立reader对象
if(!$objRead->canRead($file)){
$objRead = new PHPExcel_Reader_Excel5();
if(!$objRead->canRead($file)){
die('No Excel!');
}
}
$cellName = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'AA', 'AB', 'AC', 'AD', 'AE', 'AF', 'AG', 'AH', 'AI', 'AJ', 'AK', 'AL', 'AM', 'AN', 'AO', 'AP', 'AQ', 'AR', 'AS', 'AT', 'AU', 'AV', 'AW', 'AX', 'AY', 'AZ');
$obj = $objRead->load($file); //建立excel对象
$currSheet = $obj->getSheet($sheet); //获取指定的sheet表
$columnH = $currSheet->getHighestColumn(); //取得最大的列号
$columnCnt = array_search($columnH, $cellName);
$rowCnt = $currSheet->getHighestRow(); //获取总行数
$data = array();
for($_row=1; $_row<=$rowCnt; $_row++){ //读取内容
for($_column=0; $_column<=$columnCnt; $_column++){
$cellId = $cellName[$_column].$_row;
$cellValue = $currSheet->getCell($cellId)->getValue();
//$cellValue = $currSheet->getCell($cellId)->getCalculatedValue(); #获取公式计算的值
if($cellValue instanceof PHPExcel_RichText){ //富文本转换字符串
$cellValue = $cellValue->__toString();
}
$data[$_row][$cellName[$_column]] = $cellValue;
}
}
array_shift($data);
return $data;
}
↑↑↑↑↑↑这是我用的方法
以下是另外两种方法
1、
1. function excelToArray(){
2. require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel/IOFactory.php';
4. //加载excel文件
5. $filename = dirname(__FILE__).'/result.xlsx';
6. $objPHPExcelReader = PHPExcel_IOFactory::load($filename);
8. $sheet = $objPHPExcelReader->getSheet(0); // 读取第一个工作表(编号从 0 开始)
9. $highestRow = $sheet->getHighestRow(); // 取得总行数
10. $highestColumn = $sheet->getHighestColumn(); // 取得总列数
12. $arr = array('A','B','C','D','E','F','G','H','I','J','K','L','M', 'N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
13. // 一次读取一列
14. $res_arr = array();
15. for ($row = 2; $row <= $highestRow; $row++) {
16. $row_arr = array();
17. for ($column = 0; $arr[$column] != 'F'; $column++) {
18. $val = $sheet->getCellByColumnAndRow($column, $row)->getValue();
19. $row_arr[] = $val;
20. }
22. $res_arr[] = $row_arr;
23. }
25. return $res_arr;
26. }
2、
1. function excelToArray(){
2. require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel/IOFactory.php';
4. //加载excel文件
5. $filename = dirname(__FILE__).'/result.xlsx';
6. $objPHPExcelReader = PHPExcel_IOFactory::load($filename);
8. $reader = $objPHPExcelReader->getWorksheetIterator();
9. //循环读取sheet
10. foreach($reader as $sheet) {
11. //读取表内容
12. $content = $sheet->getRowIterator();
13. //逐行处理
14. $res_arr = array();
15. foreach($content as $key => $items) {
17. $rows = $items->getRowIndex(); //行
18. $columns = $items->getCellIterator(); //列
19. $row_arr = array();
20. //确定从哪一行开始读取
21. if($rows < 2){
22. continue;
23. }
24. //逐列读取
25. foreach($columns as $head => $cell) {
26. //获取cell中数据
27. $data = $cell->getValue();
28. $row_arr[] = $data;
29. }
30. $res_arr[] = $row_arr;
31. }
33. }
35. return $res_arr;
36. }
二、Excel文件导出
1. /**
2. * 创建(导出)Excel数据表格
3. * @param array $list 要导出的数组格式的数据
4. * @param string $filename 导出的Excel表格数据表的文件名
5. * @param array $indexKey $list数组中与Excel表格表头$header中每个项目对应的字段的名字(key值)
6. * @param array $startRow 第一条数据在Excel表格中起始行
7. * @param [bool] $excel2007 是否生成Excel2007(.xlsx)以上兼容的数据表
8. * 比如: $indexKey与$list数组对应关系如下:
9. * $indexKey = array('id','username','sex','age');
10. * $list = array(array('id'=>1,'username'=>'YQJ','sex'=>'男','age'=>24));
11. */
12. function exportExcel($list,$filename,$indexKey,$startRow=1,$excel2007=false){
13. //文件引入
14. require_once APP_ROOT.'/Api/excel/PHPExcel.php';
15. require_once APP_ROOT.'/Api/excel/PHPExcel/Writer/Excel2007.php';
17. if(empty($filename)) $filename = time();
18. if( !is_array($indexKey)) return false;
20. $header_arr = array('A','B','C','D','E','F','G','H','I','J','K','L','M', 'N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
21. //初始化PHPExcel()
22. $objPHPExcel = new PHPExcel();
24. //设置保存版本格式
25. if($excel2007){
26. $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
27. $filename = $filename.'.xlsx';
28. }else{
29. $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
30. $filename = $filename.'.xls';
31. }
33. //接下来就是写数据到表格里面去
34. $objActSheet = $objPHPExcel->getActiveSheet();
35. //$startRow = 1;
36. foreach ($list as $row) {
37. foreach ($indexKey as $key => $value){
38. //这里是设置单元格的内容
39. $objActSheet->setCellValue($header_arr[$key].$startRow,$row[$value]);
40. }
41. $startRow++;
42. }
44. // 下载这个表格，在浏览器输出
45. header("Pragma: public");
46. header("Expires: 0");
47. header("Cache-Control:must-revalidate, post-check=0, pre-check=0");
48. header("Content-Type:application/force-download");
49. header("Content-Type:application/vnd.ms-execl");
50. header("Content-Type:application/octet-stream");
51. header("Content-Type:application/download");;
52. header('Content-Disposition:attachment;filename='.$filename.'');
53. header("Content-Transfer-Encoding:binary");
54. $objWriter->save('php://output');
55. }
导出文件，还可以设置模板
1. function exportExcel($list,$filename,$indexKey=array()){
2. require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel/IOFactory.php';
3. require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel.php';
4. require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel/Writer/Excel2007.php';
6. $header_arr = array('A','B','C','D','E','F','G','H','I','J','K','L','M', 'N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
8. //$objPHPExcel = new PHPExcel(); //初始化PHPExcel(),不使用模板
9. $template = dirname(__FILE__).'/template.xls'; //使用模板
10. $objPHPExcel = PHPExcel_IOFactory::load($template); //加载excel文件,设置模板
12. $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel); //设置保存版本格式
14. //接下来就是写数据到表格里面去
15. $objActSheet = $objPHPExcel->getActiveSheet();
16. $objActSheet->setCellValue('A2', "活动名称：江南极客");
17. $objActSheet->setCellValue('C2', "导出时间：".date('Y-m-d H:i:s'));
18. $i = 4;
19. foreach ($list as $row) {
20. foreach ($indexKey as $key => $value){
21. //这里是设置单元格的内容
22. $objActSheet->setCellValue($header_arr[$key].$i,$row[$value]);
23. }
24. $i++;
25. }
27. // 1.保存至本地Excel表格
28. //$objWriter->save($filename.'.xls');
30. // 2.接下来当然是下载这个表格了，在浏览器输出就好了
31. header("Pragma: public");
32. header("Expires: 0");
33. header("Cache-Control:must-revalidate, post-check=0, pre-check=0");
34. header("Content-Type:application/force-download");
35. header("Content-Type:application/vnd.ms-execl");
36. header("Content-Type:application/octet-stream");
37. header("Content-Type:application/download");;
38. header('Content-Disposition:attachment;filename="'.$filename.'.xls"');
39. header("Content-Transfer-Encoding:binary");
40. $objWriter->save('php://output');
41. }
先弄一个excel模板
然后使用该模板导出数据
