PHP导入导出Excel文件的方法

下面我来给大家介绍在php中操作excel两个实例,一个是利用PHP-ExcelReader导入excel并输出,另一种是直接输入excel并导出,下面看实例。


借助PHP-ExcelReader这个开源类,我们可以轻松地导入Excel文件数据,示例代码如下:

PHP-ExcelReader下载地址:http://sourceforge.net/projects/phpexcelreader/

例.导入Excel文件

 代码如下 复制代码

require_once 'Excel/reader.php';
$data = new Spreadsheet_Excel_Reader();
$data->setOutputEncoding('gbk');
$data->read('test.xls');
for ($i = 1; $i sheets[0]['numRows']; $i++) {
    for ($j = 1; $j sheets[0]['numCols']; $j++) {
        echo """.$data->sheets[0]['cells'][$i][$j]."",";
    }
    echo "n";
}
?>

例.phpexcel导到excel

1.    test.php

 代码如下 复制代码

require_once 'reader.php';

// ExcelFile($filename, $encoding);
$data = new Spreadsheet_Excel_Reader();

// Set output Encoding.
$data->setOutputEncoding('gbk');

//”data.xls”是指要导入到mysql中的excel文件
$data->read('data.xls');

@ $db = mysql_connect('localhost', 'root', '123456') or
       die("Could not connect to database.");//连接数据库
mysql_query("set names 'gbk'");//输出中文
mysql_select_db('mydb');       //选择数据库
error_reporting(E_ALL ^ E_NOTICE);

for ($i = 1; $i sheets[0]['numRows']; $i++) {
//以下注释的for循环打印excel表数据
/*
for ($j = 1; $j sheets[0]['numCols']; $j++) {
            echo """.$data->sheets[0]['cells'][$i][$j]."",";
           }
           echo "n";
//PHP开源代码


*/
//以下代码是将excel表数据【3个字段】插入到mysql中,根据你的excel表字段的多少,改写以下代码吧!
    $sql = "INSERT INTO test VALUES('".
               $data->sheets[0]['cells'][$i][1]."','".
                 $data->sheets[0]['cells'][$i][2]."','".
                 $data->sheets[0]['cells'][$i][3]."')";
    echo $sql.'
';
       $res = mysql_query($sql);
}

?>

例.导出excel文件


比如我需要一个做php导出 excel的的程序,只需要把相关的数据导出到excel表就可以了,这么简单的操作就不需要用那些类库什么的了。直接用header的方式就可以了:header("Content-type:application/vnd.ms-excel");

看看代码:

 代码如下 复制代码

header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:attachment;filename=Export_test.xls");
$tab="t"; $br="n";
$head="编号".$tab."备注".$br;
//输出内容如下: 
echo $head.$br;
echo  "test321318312".$tab; 
echo  "string1";
echo  $br;

echo  "330181199006061234".$tab;  //直接输出会被Excel识别为数字类型
echo  "number";
echo  $br;

echo  "="330181199006061234"".$tab;  //原样输出需要处理
echo  "string2";
echo  $br;
?>

在导出后会发现一个问题,如果数据是数字会出现一些意想不到的情况。比如,"012345",在excel中会变成"12345";如果输入身份证号码这样的长数字,在excel中会用科学计数法表示出来,并且最后的四位数字会出现偏差,变位0000等情况。这就需要把单元格设置为文本格式,方法是
echo  "="330181199006061234""如果程序是utf-8编码的,还需要用iconv函数去转码,不然是会乱码的,乱码的。

另word格式导入类似,,指定header就可以了:

 代码如下 复制代码

header("Content-Type:   application/msword");       
header("Content-Disposition:   attachment;   filename=doc.doc");
