}
}
// 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";
}Export data:
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";
