使用表创build带有MySQL数据和PHP的格式化的Excel电子表格

我正在从MySQL数据库导出数据到Excel电子表格。 我已经find了这样做的代码，它工作得很好。 它不会格式化电子表格。 这也是我创build的第一个PHP / MySQL网站，数据不需要很漂亮。 当前的项目需要格式化的数据。

昨天，我发现一篇文章可能让我做我需要做的事情。 像一个白痴，我没有复制链接。 我今天找不到。

这是我的代码 –

<?php require_once("includes/connection.php"); require_once("includes/functions.php"); // set $closed to 0 for development $closed = 0; //create a sting to allow the user to see if s/he is looking at open or closed items if ($closed) { $filename = FILENAME."_closed"; } else { $filename = FILENAME."_open"; } // $data will hold the result $data = '<table>'; // is the row a header? $th = FALSE; // define the separator character $sep = '\t'; // array for keys $thKey = array(); // are we in the first row? $firstRow = TRUE; // create the query $query = "SELECT "; $query .= "training_requirements.Training, mechanism.mechName, location.locationName, impacted_employees.groupName, "; $query .= "training_requirements.DateReceived, training_requirements.DateStart, training_requirements.DateDue, "; $query .= "requester.lastName, requester.firstName, impact.impactName, training_requirements.TimeNeeded, "; $query .= "priority.priority, training_requirements.Notes "; $query .= "FROM "; $query .= "training_requirements, impact, impacted_employees, location, mechanism, requester, priority "; $query .= "WHERE impact.impactId = training_requirements.impactId "; $query .= "AND impacted_employees.groupId = training_requirements.impEmpId "; $query .= "AND location.locationId = training_requirements.trainLocId "; $query .= "AND mechanism.mechId = training_requirements.mechId "; $query .= "AND requester.requesterId = training_requirements.requesterId "; $query .= "AND priority.id = training_requirements.Priority "; $query .= "AND training_requirements.Closed = $closed "; $query .= "AND training_requirements.Deleted = 0"; // run the query $result = executeQuery($connection, $query); // process the query if (mysqli_num_rows($result) > 0) { while ($resource = mysqli_fetch_assoc($result)) { if (empty($thKey)) { foreach($resource as $key => $value) { $thKey[] = $key; } } $data .= '<tr>'; for ($i = 0; $i < count($resource); $i++) { if ($firstRow) { // create the header for ($j = 0; $j < count($resource); $j++) { $data .= '<th>'; $data .= $thKey[$j]; $data .= '</th>'; } $data .= '</tr><tr>'; $firstRow = FALSE; } $data .= '<td>'; if (isset($resource[$thKey[$i]])) { $data .= $resource[$thKey[$i]]; } else { $data .= '&nbsp;'; } $data .= '</td>'; } $data .= '</tr>'; } $data .= '</table>'; echo $data; } //header('Content-type: application/excel'); //header("Content-Disposition: attachment; filename={$filename}.xls"); //header("Pragma: no-cache"); //header("Expires: 0"); ?> 

代码继续让我在浏览器中显示结果。 我在Firefox中获得了一个正确的表格。 当我在底部取消注释头部语句时，我得到一个空白的Excel文件。 没有细胞，没有任何东西。

使用Excel 2007（12.0.6715.5000）SP3 MSO（12.0.6721.5000），PHP 5.4.24和MySQL 5.5.40。 使用插件和库不是一个选项。

你的代码只是来自MySQL的fech数据，并没有任何excel文件。

在这里你是一个伟大的execl文件的类

纯XML代码没有任何扩展

用法：

 $xls = new Excel_XML('UTF-8', false, 'title text'); $data = array( 1 => array ('column1 text', 'coloumn2 text'), 1 => array ('column1 text', 'coloumn2 text'), 1 => array ('column1 text', 'coloumn2 text'), ); $xls -> addArray($data); $xls -> generateXML('file Name'); // its print code to browser use requred header to download
