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++;
