本文实例讲述了CI框架(CodeIgniter)实现的导入、导出数据操作。分享给大家供大家参考,具体如下:
在libraies中引用PHPExcel这个类(phpexcel.php)
public function excel_put(){ //先做一个文件上传,保存文件 $path=$_FILES['file']; $filePath = "uploads/".$path["name"]; move_uploaded_file($path["tmp_name"],$filePath); //$data=array('B'=>'name','C'=>'pwd','D'=>'money1','E'=>'salt'); $data=array('B'=>'name','C'=>'pid'); $tablename='city2';//表名字 $this->excel_fileput($filePath,$data,$tablename); }
private function excel_fileput($filePath,$data,$tablename){ $this->load->library("phpexcel");//ci框架中引入excel类 $PHPExcel = new PHPExcel(); $PHPReader = new PHPExcel_Reader_Excel2007(); if(!$PHPReader->canRead($filePath)){ $PHPReader = new PHPExcel_Reader_Excel5(); if(!$PHPReader->canRead($filePath)){ echo 'no Excel'; return ; } } // 加载excel文件 $PHPExcel = $PHPReader->load($filePath); // 读取excel文件中的第一个工作表 $currentSheet = $PHPExcel->getSheet(0); // 取得最大的列号 $allColumn = $currentSheet->getHighestColumn(); // 取得一共有多少行 $allRow = $currentSheet->getHighestRow(); // 从第二行开始输出,因为excel表中第一行为列名 for($currentRow = 2;$currentRow <= $allRow;$currentRow++){ /**从第A列开始输出*/ //echo $allColumn; for($currentColumn= 'A';$currentColumn<= $allColumn; $currentColumn++){ $val = $currentSheet->getCellByColumnAndRow(ord($currentColumn) - 65,$currentRow)->getValue(); //print_r($val); //die; if($currentColumn == 'A') { //echo $val."\t"; }else if($currentColumn <= $allColumn){ $data1[$currentColumn]=$val; } } foreach($data as $key=>$val){ $data2[$val]=$data1[$key]; } $this->db->insert($tablename,$data2); //print_r($data2); //echo "</br>"; } //echo "\n"; echo "导入成功"; }
导出数据:
public function excel_out(){ header("Content-type:text/html"); header("Content-Disposition:attachment;filename=123.xls"); $array=$this->db->get("city")->result_array(); $str="id\t"."name\t"."pid\n"; foreach($array as $val){ $str.=$val['id']."\t".$val['name']."\t".$val['pid']."\n"; } echo $str; }
希望本文所述对大家基于CodeIgniter框架的PHP程序设计有所帮助。
