PHP实现.csv文件的上传与下载－Mysql

上传：

<?php

$mysql_hostname = "你的数据库IP地址";

$mysql_user = "你的数据库登陆名";

$mysql_password = "登陆密码";

$mysql_database = "你的数据库中所使用的database";
$prefix = "";

//如果没有链接上，会报错“Opps some thing went wrong”
$db = @mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Opps some thing went wrong");
mysql_select_db($mysql_database, $db) or die("Opps some thing wrong!!");
mysql_query("set character set 'utf8'");
mysql_query("set names 'utf8'");

//fopen的地址是绝对路径，如果你使用的是linux，直接用PWD就可以把路径显示出来

$file = fopen("/Applications/mamp/htdocs/address.csv", "r+") or exit("Unable to open file!");
if (!feof($file)) {
while ($data = fgetcsv($file)) {

 

//data[0]位这个.csv文件的第一列

$da = $data[0];
var_dump($da);

$sql = "INSERT INTO 你的表名 (字段名) 
VALUES('" . $da . "')";

mysql_query($sql);

}
}
fclose($file);
echo "数据导入成功";
?>
