大概尝试有四种方法
一、思路:拼接成表格转化为浏览器输出
/* *处理Excel导出 *@param $datas array 设置表格数据 *@param $titlename string 设置head *@param $title string 设置表头 */ public function excelData($datas,$titlename,$title,$filename){ $str = "<html xmlns:o=\"urn:schemas-microsoft-com:office:office\"\r\nxmlns:x=\"urn:schemas-microsoft-com:office:excel\"\r\nxmlns=\"http://www.w3.org/TR/REC-html40\">\r\n<head>\r\n<meta http-equiv=Content-Type content=\"text/html; charset=utf-8\">\r\n</head>\r\n<body>"; $str .="<table border=1><head>".$titlename."</head>"; $str .= $title; foreach ($datas as $key=> $rt ) { $str .= "<tr>"; foreach ( $rt as $k => $v ) { //防止乱码 $str .= "<td>iconv("UTF-8","GB2312",{$v})</td>"; } $str .= "</tr>\n"; } $str .= "</table></body></html>"; header( "Content-Type: application/vnd.ms-excel; name=\'excel\'" ); header( "Content-type: application/octet-stream" ); header( "Content-Disposition: attachment; filename=".$filename ); header( "Cache-Control: must-revalidate, post-check=0, pre-check=0" ); header( "Pragma: no-cache" ); header( "Expires: 0" ); exit( $str ); } $dataResult = array(); //todo:导出数据(自行设置) $headTitle = "XX保险公司 优惠券赠送记录"; $title = "优惠券记录"; $headtitle= "<tr style=\'height:50px;border-style:none;><th border=\"0\" style=\'height:60px;width:270px;font-size:22px;\' colspan=\'11\' >{$headTitle}</th></tr>"; $titlename = "<tr> <th style=\'width:70px;\' >合作商户</th> <th style=\'width:70px;\' style=\'vdn.ms-excel.numberformat:@\' >会员卡号</th> <th style=\'width:70px;\'>车主姓名</th> <th style=\'width:150px;\'>手机号</th> <th style=\'width:70px;\'>车牌号</th> <th style=\'width:100px;\'>优惠券类型</th> <th style=\'width:70px;\'>优惠券名称</th> <th style=\'width:70px;\'>优惠券面值</th> <th style=\'width:70px;\'>优惠券数量</th> <th style=\'width:70px;\'>赠送时间</th> <th style=\'width:90px;\'>截至有效期</th> </tr>"; $filename = $title.".xls"; $this->excelData($dataResult,$titlename,$headtitle,$filename);
这个方法PHP在输出EXCEL表格时,经常会碰到如下问题,如有些物料编号是数字0开头的,产生EXCEL后,会发现数字0会丢失;还有类似"1-3"这种纯文本格式的导出后会自动转化为日期型格式。
我们可以通过如下方式去规定数据保存的格式:
1)文本:vnd.ms-excel.numberformat:@
2)日期:vnd-ms-excel.numberformat:yyyy/mm/dd
3)数字:vnd-ms-excel.numberformat:#,##0.00
4)货币:vnd-ms-excel.numberformat:$#,##0.00
5)百分比:vnd-ms-excel.numberformat:#0.00%
二、使用phpexcel ,引入该类就行了,但是数据量过万的时候,就很容易崩溃了
三、导出cvs文件
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)) { $cnt ++; if ($limit == $cnt) { //刷新一下输出buffer,防止由于数据过多造成阻塞问题 ob_flush(); flush(); $cnt = 0; } foreach ($row as $i => $v) { $row[$i] = iconv(\'utf-8\', \'gbk\', $v); } fputcsv($fp, $row); }
这种方法大约处理50万左右的数据
四、写入内存下载
public function exportAction() { set_time_limit(0); ini_set(\'memory_limit\', \'1024M\'); //获取数据 $data="你的数据"; //二维数组,可以分页读取,一次读多少条 $excelFilename="download/allOrderExcel.csv"; $header=array(); $header[]=iconv("UTF-8","GB2312","订单ID"); $header[]=iconv("UTF-8","GB2312","类型"); $header[]=iconv("UTF-8","GB2312","状态"); $header[]=iconv("UTF-8","GB2312","个数"); $header[]=iconv("UTF-8","GB2312","备注"); $header[]=iconv("UTF-8","GB2312","创建时间"); $header[]=iconv("UTF-8","GB2312","更新时间"); $header[]=iconv("UTF-8","GB2312","完成时间"); $header[]=iconv("UTF-8","GB2312","地址"); $header[]=iconv("UTF-8","GB2312","用户名"); $header[]=iconv("UTF-8","GB2312","真实姓名"); $header[]=iconv("UTF-8","GB2312","手机号"); $headerFile = implode(\',\', $header); file_put_contents($excelFilename,$headerFile."\n"); if(!$handle=fopen($excelFilename,\'a\')){ echo "文件打开失败"; exit; } foreach ($data as $val){ //将每个数组,拼接成字符串,写入文件 $filecontent[]=implode(\',\',$val); } foreach ($filecontent as $content){ //遍历数组,一条一条写入 fwrite($handle,$content."\n"); } fclose($handle); header("Content-type: application/octet-stream"); header(\'Content-Disposition: attachment; filename="\' . basename($excelFilename) . \'"\'); header("Content-Length: ". filesize($excelFilename)); readfile($excelFilename); exit; }
数字显示不完整?变成科学计数法了?
这个问题是因为Excel显示数字时,如果数字大于12位,它会自动转化为科学计数法;如果数字大于15位,它不仅用于科学技术费表示,还会只保留高15位,其他位都变0。
解决这个问题:
只要把数字字段后面加上显示上看不见的字符即可,字符串前面或者结尾加上制表符"\t".
php 程序可以这样判断,注意一定是"\t",不是\'\t\'.(双引号)
