实例一：
<?php

//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”;

[‘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){

}
示例二：
//从数据库中导出
$conn = mysqli_connect(‘localhost’,’root’,’123456′,’st0614′);//连接数据库

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’;

$fp = fopen($filename,’r’);

if($i==1)
{
continue;//过滤表头
}else{

}
}
fclose($fp);
}
