检索数据库中的表到phpexcel

我正在使用PHP Excel导出数据库中的数据到Excel格式。 我可以从数据库检索所有的数据到Excel。 但是，如果我想要检索表的列名称，我该怎么做。 任何人都可以帮忙

这是我的代码：

<?php header("Content-Type:application/vnd.ms-excel"); header("Content-Disposition:attachment;filename=product.xls"); header("Pragma:no-cache"); header("Expires:0"); header('Content-Type: text/html; charset=UTF-8'); header("Content-type: application/octetstream"); header('Content-Disposition: attachment; filename="export.csv"'); /** Error reporting */ error_reporting(E_ALL); ini_set('display_errors', TRUE); ini_set('display_startup_errors', TRUE); date_default_timezone_set('Europe/London'); if (PHP_SAPI == 'cli') die('This example should only be run from a Web Browser'); /** Include PHPExcel */ require_once '../Classes/PHPExcel.php'; require_once '../Classes/PHPExcel/Writer/Excel2007.php'; require_once '../Classes/PHPExcel/IOFactory.php'; $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("litako", $con); $objPHPExcel = new PHPExcel(); $res= mysql_query("SELECT * FROM vendorlist "); /** Error reporting */ error_reporting(E_ALL); date_default_timezone_set('Europe/London'); $objPHPExcel = new PHPExcel(); if(!$res){ die("Error"); } $col = 0; $row = 3; while($mrow = mysql_fetch_assoc($res)) { $col = 0; foreach($mrow as $key=>$value) { $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value); $col++; } $row++; } // Set active sheet index to the first sheet, so Excel opens this as the first sheet $objPHPExcel->setActiveSheetIndex(0); // Save Excel 2007 file $objPHPExcel->setActiveSheetIndex(0); header('Content-Type: application/vnd.ms-excel'); header('Content-Disposition: attachment;filename="report.xls"'); header('Cache-Control: max-age=0'); // If you're serving to IE 9, then the following may be needed header('Cache-Control: max-age=1'); // If you're serving to IE over SSL, then the following may be needed header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past header ('Last-Modified: '.gmdate('D, d MYH:i:s').' GMT'); // always modified header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1 header ('Pragma: public'); // HTTP/1.0 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); $objWriter->save('php://output'); exit;

您在您的while循环中已经有了名称为mysql_fetch_assoc的列名称。 $ key值是列名称。 所以这里是你的代码的更新部分：

  while($mrow = mysql_fetch_assoc($res)) { $col = 0; foreach($mrow as $key=>$value) { // TODO: Do Something With the Column Name like set the row header. Note this crude code sets it every time. You really just want to do it the first time only. $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 0, $key); $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row + 1, $value); $col++; } $row++; }
