基于PHPexecl类生成复杂的报表表头示例

本文实例讲述了基于phpexecl类生成复杂的报表表头。分享给大家供大家参考，具体如下：

以前一直有需求，能把execl里面的数据导入数据库，并且把数据库里面的数据导出到execl中。

require_once dirname(__file__) . '/../classes/phpexcel/iofactory.php';
class phpexeclcore extends phpexcel_iofactory{
 public static function summercreateexecl($head,$data)
 {
 self::summercreateexeclhead($head,$data,"excel2007");
 }
 public static function summerreadexecl($dir)
 {
 if(!file_exists($dir))
 {
 echo "execl not exist";
 }
 else
 {
 $phpexeclobj = self::load($dir);
 $sheetcount = $phpexeclobj->getsheetcount(); //得到execl中包含的sheet工作簿的数量
 for($i=0;$i<$sheetcount;$i++)
 {
 $activesheet = $phpexeclobj->getsheet($i);
 $highestrow = $activesheet->gethighestrow(); // 取得总列数
 $allcolumn = $activesheet->gethighestcolumn();
 //通过嵌套循环来读取sheet工作簿里面的内容
 for($col='a';$col<$allcolumn;$col++)
 {
 for($row=1;$row<$highestrow;$row++)
 {
 $data[$col][$row] = $activesheet->getcell($col.$row)->getvalue();
 }
 }
 }
 }
 return $data;
 }
 /*

 * $data array 表示要插入进execl数据
 * $ruledata array 表示数据格式的规则数组
 * $i int 表示从第几行起的插入数据
 * **/
 public static function summerinsertdatetoexecl($sheet,$head,$data,$n=3,$ruledata=array())
 {
 $simplehead = self::gethead($head);
 $row = $n;
 foreach($data as $key=>$valuearr)
 {
 $m = 0;
 foreach($valuearr as $k=>$v)
 {
 $startcol = phpexcel_cell::stringfromcolumnindex($m).$row;
 $sheet->getcell($startcol)->setvalue($v);
 $sheet->getstyle($startcol)->getalignment()->applyfromarray(
 array(
 'horizontal'=> phpexcel_style_alignment::horizontal_center,
 'vertical' => phpexcel_style_alignment::vertical_center,
 'rotation' => 0,
 'wrap' => true,
 )
 );
 if(isset($simplehead[$k]['col']))
 {
 $m = $m + $simplehead[$k]['col']-1;
 $endcol = phpexcel_cell::stringfromcolumnindex($m).$row;
 $sheet->mergecells($startcol.":".$endcol);
 }
 $m++;

 }

 }

 }

得到的效果也基本符合需求：
