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;
}
/*

public static function SummerInsertDateToExecl($sheet,$Head,$Data,$n=3,$RuleData=array())
{

$row = $n;
foreach($Data as $key=>$valueArr)
{
$m = 0;

{

if(isset($SimpleHead[$k]['col']))

得到的效果也基本符合需求：
希望本文所述对大家PHP程序设计有所帮助。
