PHP Excel导入和导出

导入：

<?php
//获取excel内容
$str = file_get_contents('use.xls');
//去除字符串两边空格
$str = trim($str);
//通过回车把字符串分割成数组
$arr = explode("\n",$str);
//处理数组通过\t（制表符）
foreach($arr as $k=>$v){
if($k!=0){
$data[] = explode("\t",$v);
}
}
//连接数据库
$link = mysql_connect('127.0.0.1','root','root') or die('no');
mysql_select_db('test',$link) or die('yes');
//由于excel编码格式问题 必须设置为gbk
mysql_query('set names gbk');
//$sql = '';
foreach($data as $k=>$v){
$sql = "insert into user(username,pwd) values('$v[1]','$v[2]')";
$info = mysql_query($sql);
//print_r($info);die;
}

?>


导出：
<?php
header("content-type:text/html;charset=utf-8");
//exit;
$link=mysql_connect("127.0.0.1","root",'root');
mysql_select_db($link,'test');
mysql_query("set names utf8");
$sql="select * from user";
$res=mysql_query($sql);
while($row=mysql_fetch_assoc($res)){
$data[]=$row;
}
//var_dump($data);
$str="编号\t姓名\t密码"."\n";
foreach($data as $key=>$v){
$str.=implode("\t",$v)."\n";
}
header("content-type:application/vnd.ms-excel");
header("content-disposition:attachment;filename=use.xls");
echo $str;
