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！\';
}
}
