php 数据批量导入csv的简单例子

<?php
//定义获取时间函数
function getmicrotime(){
list($usec, $sec) = explode(" ",microtime());
return ((float)$usec + (float)$sec);
}

//数据库连接
$time_start = getmicrotime();
include("db.inc.php");//连接数据库
$db=new testcsv;

//导入csv数据
// by http://www.jquerycn.cn
$handle = fopen ("test.csv","r");
$sql="insert into scores(idcard,names,num,sex,nation,score) values('";
while ($data = fgetcsv ($handle, 1000, ",")) {
$num = count ($data);
for ($c=0; $c < $num; $c++) {
if($c==$num-1){$sql=$sql.$data[$c]."')";break;}
$sql=$sql.$data[$c]."','";
}
print "<br>";
echo $sql."<br>";
$db->query($sql);
echo "执行成功！<br>";
$sql="insert into scores(idcard,names,num,sex,nation,score) values('";
}
fclose ($handle);
$time_end = getmicrotime();
$time = $time_end - $time_start;
echo "执行时间：".$time."秒";
?>
