利用php导出mysql数据库为excel表格的方法很多,最简单的就直接使用php fputcsv函数了,还有就是直接输入csv格式也是可以了,要生成excel标准格式我们需使用第三方插件了.
方法一,利用fputcsv,代码如下:
// 输出Excel文件头,可把user.csv换成你要的文件名 header('Content-Type: application/vnd.ms-excel'); header('Content-Disposition: attachment;filename="user.csv"'); header('Cache-Control: max-age=0'); // 从数据库中获取数据,为了节省内存,不要把数据一次性读到内存,从句柄中一行一行读即可 $sql = 'select * from tbl where ……'; $stmt = $db->query($sql); // 打开PHP文件句柄,php://output 表示直接输出到浏览器 $fp = fopen('php://output', 'a'); // 输出Excel列名信息 $head = array('姓名', '性别', '年龄', 'Email', '电话', '……'); foreach ($head as $i => $v) { // CSV的Excel支持GBK编码,一定要转换,否则乱码 $head[$i] = iconv('utf-8', 'gbk', $v); } // 将数据通过fputcsv写到文件句柄 fputcsv($fp, $head); // 计数器 $cnt = 0; // 每隔$limit行,刷新一下输出buffer,不要太大,也不要太小 $limit = 100000; // 逐行取出数据,不浪费内存 while ($row = $stmt->fetch(Zend_Db::FETCH_NUM)) { //开源代码phprm.com $cnt ++; if ($limit == $cnt) { //刷新一下输出buffer,防止由于数据过多造成问题 ob_flush(); flush(); $cnt = 0; } foreach ($row as $i => $v) { $row[$i] = iconv('utf-8', 'gbk', $v); } fputcsv($fp, $row); }
方法二,直接在浏览器用header输出csv格式的数据,代码如下:
<?php /*连接数据库*/ $DB_Server = "localhost"; $DB_Username = "root"; $DB_Password = "123456"; $DB_DBName = "mydb"; //目标数据库名 $DB_TBLName = "mytable"; //目标表名 $Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect."); mysql_query("Set Names 'utf8'"); $savename = date("YmjHis"); //导出excel文件名 $file_type = "vnd.ms-excel"; $file_ending = "xls"; header("Content-Type: application/$file_type;charset=utf8"); header("Content-Disposition: attachment; filename=" . $savename . ".$file_ending"); //header("Pragma: no-cache"); /*写入备注信息*/ $now_date = date("Y-m-j H:i:s"); $title = "数据库名:$DB_DBName,数据表:$DB_TBLName,备份日期:$now_date"; echo ("$title\n"); /*查询数据库*/ $sql = "Select * from $DB_TBLName"; $ALT_Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database"); $result = @mysql_query($sql, $Connect) or die(mysql_error()); /*写入表字段名*/ for ($i = 0; $i < mysql_num_fields($result); $i++) { echo mysql_field_name($result, $i) . ","; } echo "\n"; /*写入表数据*/ $sep = ",t"; while ($row = mysql_fetch_row($result)) { $data = ""; for ($i = 0; $i < mysql_num_fields($result); $i++) { if (!isset($row[$i])) $data.= "NULL" . $sep; //处理NULL字段 elseif ($row[$i] != "") $data.= "$row[$i]" . $sep; else $data.= "" . $sep; //处理空字段 } echo $data . "\n"; }
例3, 第二个差不多了, 代码如下:
//搜索 $start_time = strtotime($start_date); $end_time = strtotime($end_date); $sql = "select a.*,b.order_amount,b.money_paid from " . $ecs->table('invoice') . " as a " . " left join " . $ecs->table('order_info') . " as b on a.order_id=b.order_s\n" . " where a.add_time >=" . $start_time . " and a.add_time <=" . $end_time . " "; $temp_list = $db->getAll($sql); if ($temp_list) { //有数据 $Html = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><body>' . chr(13) . chr(10); $Html.= '<table width="700" border="1" align="center" cellpadding="2" cellspacing="1"> <tr align="center"> <td align="center" nowrap="nowrap">时间:</td> <td align="center" nowrap="nowrap" colspan="9">' . $start_date . '~' . $end_date . '</td> </tr> <tr align="center"> <td align="center" nowrap="nowrap">编号</td> <td align="center" nowrap="nowrap">发票类型</td> <td align="center" nowrap="nowrap">发票抬头</td> <td align="center" nowrap="nowrap">发票内容</td> <td align="center" nowrap="nowrap">订单号</td> <td align="center" nowrap="nowrap">金额</td> <td align="center" nowrap="nowrap">添加日期</td> <td align="center" nowrap="nowrap">收件人</td> <td align="center" nowrap="nowrap">联系方式</td> <td align="center" nowrap="nowrap">地址</td> </tr>'; //取得符合条件的数组 for ($i = 0; $i < count($temp_list); $i++) { $temp_i = $i + 1; if ($temp_list[$i][order_amount] == 0) { $temp_money = $temp_list[$i][money_paid]; } else { $temp_money = $temp_list[$i][order_amount]; } $temp_time = date('Y-m-d', $temp_list[$i]['add_time']); $Html.= '<tr align="center"> <td align="center" nowrap="nowrap">' . $temp_i . '</td> <td align="center" nowrap="nowrap">' . $temp_list[$i][type_name] . '</td> <td align="center" nowrap="nowrap">' . $temp_list[$i][top] . '</td> <td align="center" nowrap="nowrap">' . $temp_list[$i][content] . '</td> <td align="center" nowrap="nowrap" style="vnd.ms-excel.numberformat:@">' . $temp_list[$i][order_id] . '</td> <td align="center" nowrap="nowrap">' . $temp_money . '</td> <td align="center" nowrap="nowrap">' . $temp_time . '</td> <td align="center" nowrap="nowrap">' . $temp_list[$i][user_name] . '</td> <td align="center" nowrap="nowrap">' . $temp_list[$i][mobile] . ' ' . $temp_list[$i][tel] . ' </td> <td align="center" nowrap="nowrap">' . $temp_list[$i][address] . '</td> </tr>'; } $Html.= '</table>'; $Html.= '</body></html>'; $mime_type = 'application/vnd.ms-excel'; header('Content-Type: ' . $mime_type); header('Content-Disposition: attachment; filename="invoice.xls"'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); echo $Html;
有时excel会自动把数字转换格式, 于是有些手机号码, 身份证之类的就乱了, 因此可以在导出时, 先定义好如下代码: '.$temp_list[$i][order_id].'
