HomeBackend DevelopmentPHP Tutorial使用PHP导入Excel和导出数据为Excel文件

有时需要将Excel表格的数据导入到mysql数据库中,我们使用PHP的一个开源项目PHP-ExcelReader可以轻松实现Excel的导入。

1、导入XLS

PHP-ExcelReader这是一个开源的项目,主要是来解析excel的文件,您可以到 http://sourceforge.net/projects/phpexcelreader获取最新版的源码。下载之后解压,主要用到excel文件夹里面的两个文件reader.php和oleread.inc。

导入Xls处理流程:选择xls文件->上传xls文件到服务器->通过PHP-ExcelReader解析excel->批量入库。

include_once("excel/reader.php"); //引入PHP-ExcelReader$tmp = $_FILES['file']['tmp_name'];if (empty ($tmp)) {	echo '请选择要导入的Excel文件!';	exit;}	$save_path = "xls/";$file_name = $save_path.date('Ymdhis') . ".xls"; //上传后的文件保存路径和名称if (copy($tmp, $file_name)) {	$xls = new Spreadsheet_Excel_Reader();	$xls->setOutputEncoding('utf-8');  //设置编码	$xls->read($file_name);  //解析文件	for ($i=2; $i<=$xls->sheets[0]['numRows']; $i++) {		$name = $xls->sheets[0]['cells'][$i][0];		$sex = $xls->sheets[0]['cells'][$i][1];		$age = $xls->sheets[0]['cells'][$i][2];		$data_values .= "('$name','$sex','$age'),";	}	$data_values = substr($data_values,0,-1); //去掉最后一个逗号	$query = mysql_query("insert into student (name,sex,age) values $data_values");//批量插入数据表中	if($query){		echo '导入成功!';	}else{		echo '导入失败!';	}}

PHP-ExcelReader读取上传的excel文件后,返回一个数组,里面包含了表格的所有信息,你可以循环获取需要的信息。

2、导出XLS

导出XLS流程:读取学生信息表->循环记录构建制表符分隔的字段信息->设置header信息->导出文件(下载)到本地

$result = mysql_query("select * from student");$str = "姓名\t性别\t年龄\t\n";$str = iconv('utf-8','gb2312',$str);while($row=mysql_fetch_array($result)){    $name = iconv('utf-8','gb2312',$row['name']);    $sex = iconv('utf-8','gb2312',$row['sex']);    $str .= $name."\t".$sex."\t".$row['age']."\t\n";}$filename = date('Ymd').'.xls';exportExcel($filename,$str);

exportExcel函数用于设置header信息。

function exportExcel($filename,$content){ 	header("Cache-Control: must-revalidate, post-check=0, pre-check=0");	header("Content-Type: application/vnd.ms-execl");	header("Content-Type: application/force-download");	header("Content-Type: application/download");    header("Content-Disposition: attachment; filename=".$filename);    header("Content-Transfer-Encoding: binary");    header("Pragma: no-cache");    header("Expires: 0");    echo $content;}

此外,关于导入和导出Excel,还可以使用PHPExcel,这个非常强大,大家有空可以去研究,官方网站: http://www.codeplex.com/PHPExcel 导入导出都成,可以导出office2007格式,同时兼容2003
