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; } /* * 将数据写入到数据表中 * $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++; $type = false; if(isset($SimpleHead[$k]['type'])) { $type = $SimpleHead[$k]['type']; $AllowArray = $SimpleHead[$k]['allowarray']; } //设置单元格的数据验证 if($type) { switch ($type) { case 'list': self::setSelectionRange($sheet, $StartCol,$AllowArray); break; case 'range': self::setValueRange($sheet, $StartCol,$AllowArray); break; } } } $row ++ ; } } /* * 生成Execl单元格备注 * $sheet 当前的工作簿对象 * $Cell 需要设置属性的单元格 * $content 备注内容 * */ private static function setComment($sheet,$Cell,$content) { $sheet->getComment($Cell)->setAuthor('4399om'); $objCommentRichText = $sheet->getComment($Cell)->getText()->createTextRun('4399om:'); $objCommentRichText->getFont()->setBold(true); $sheet->getComment($Cell)->getText()->createTextRun(" "); $sheet->getComment($Cell)->getText()->createTextRun($content); $sheet->getComment($Cell)->setWidth('100pt'); $sheet->getComment($Cell)->setHeight('100pt'); $sheet->getComment($Cell)->setMarginLeft('150pt'); $sheet->getComment($Cell)->getFillColor()->setRGB('EEEEEE'); } /* * 现在单元格的有效数据范围，暂时仅限于数字 * $sheet 当前的工作簿对象 * $Cell 需要设置属性的单元格 * $ValueRange array 允许输入数组的访问 */ private static function setValueRange($sheet,$Cell,$ValueRange) { //设置单元格的的数据类型是数字，并且保留有效位数 $sheet->getStyle($Cell)->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_NUMBER_00); $ValueRange = explode(",",$ValueRange); //开始数值有效访问设定 $objValidation = $sheet->getCell($Cell)->getDataValidation(); $objValidation->setType( PHPExcel_Cell_DataValidation:: TYPE_WHOLE ); $objValidation->setErrorStyle( PHPExcel_Cell_DataValidation:: STYLE_STOP ); $objValidation->setAllowBlank(true); $objValidation->setShowInputMessage( true); //设置显示提示信息 $objValidation->setShowErrorMessage( true); //设置显示错误信息 $objValidation->setErrorTitle('输入错误'); //错误标题 $objValidation->setError('请输入数据范围在从'.$ValueRange[0].'到'.$ValueRange[1].'之间的所有值'); //错误内容 $objValidation->setPromptTitle('允许输入'); //设置提示标题 $objValidation->setPrompt('请输入数据范围在从'.$ValueRange[0].'到'.$ValueRange[1].'之间的所有值'); //提示内容 $objValidation->setFormula1($ValueRange['0']); //设置最大值 $objValidation->setFormula2($ValueRange['1']); //设置最小值 } private static function OutinputHeader($objWriter) { $fileName = str_replace('.php', '.xlsx', pathinfo(__FILE__, PATHINFO_BASENAME)); header("Content-Type: application/force-download"); header("Content-Type: application/octet-stream"); header("Content-Type: application/download"); header('Content-Disposition:inline;filename="'.$fileName.'"'); header("Content-Transfer-Encoding: binary"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") .

得到的效果也基本符合需求：
