标签:download   sub   csv   select   取数   attach   icon   click   excel   

实例一:

<?php
$filename = ‘test‘;
//导出文件
header("Content-type: application/vnd.ms-excel; charset=utf-8");
Header("Content-Disposition: attachment; filename=".$filename.".csv");

echo "商品名称,商品编号,商品价格,商品品牌,商品颜色\n";

$arr = [
[‘貂秋1‘,‘dq00001‘,‘1000‘,‘雕牌‘,‘红色‘],
[‘貂秋2‘,‘dq00002‘,‘1000‘,‘雕牌‘,‘蓝色‘],
[‘貂秋3‘,‘dq00003‘,‘1000‘,‘雕牌‘,‘绿色‘],
[‘貂秋4‘,‘dq00004‘,‘1000‘,‘雕牌‘,‘白色‘]
];
//将数组循环遍历并输出
foreach ($arr as $item){
echo implode(‘,‘,$item)."\n";
}

 

示例二:

//从数据库中导出

$conn = mysqli_connect(‘localhost‘,‘root‘,‘123456‘,‘st0614‘);//连接数据库

$filename = ‘student‘;//文件名为student
header("Content-type: application/vnd.ms-excel; charset=utf-8");
Header("Content-Disposition: attachment; filename=".$filename.".csv");

$res = mysqli_query($conn,‘select * from student‘);
echo "ID,姓名,性别,年龄,院系,班级,头像\n";//表头
while($row = mysqli_fetch_assoc($res))//获取数据库数据
{
$arr[] = $row;
}
foreach ($arr as $item){
echo implode(‘,‘,$item)."\n";//输出
}

//SVN导入数据库

$file = ‘text.txt‘;
if (isset($_POST[‘commit‘])){
$file = $_FILES[‘csv‘];
$fileName=$file[‘tmp_name‘];

$fp = fopen($fileName,‘r‘);
$i=0;
while ($file_data = fgetcsv($fp))
{
$i++;
if($i==1)
{
continue;//过滤表头
}else{
$data[$i] = $file_data;
}

}
fclose($fp);
}

<-- ---------请分开--------- -->
//存入数据库
if (isset($data)){
foreach ($data as $item){
   $name = iconv(‘gb2312‘,‘utf-8‘,$item[1]);
   $sql = "insert into student(`name`,`sex`,`age`,`d_id`,`class_id`,`tumble`) values(‘{$name}‘,{$item[2]},{$item[3]},{$item[4]},{$item[5]},‘{$item[6]}‘)";
   $res = mysqli_query($conn,$sql);
}
 if ($res){
   echo ‘上传成功!‘;
 }else{
   echo ‘上传失败!‘;
 }
}
