我有一个csv文件。我正在尝试读取此文件并将数据导入mysql数据库。
例如
OrderID,ProductId,ProductDescription 100001962,15,Product1 "",32,Product2 "",31,Product3 100001546,24,Product4
我如何拥有我的数据库
100001962,15,Product1 100001962,32,Product2 100001962,31,Product3 100001546,24,Product4
new.php
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="csv" value="" />
<input type="submit" name="submit" value="Save" />
</form>
</body>
</html>
upload.php的
header('Content-Type: text/html; charset=UTF-8');
require_once 'db.php';
if($_FILES['csv']['error'] == 0){
$name = $_FILES['csv']['name'];
$ext = strtolower(end(explode('.', $_FILES['csv']['name'])));
$type = $_FILES['csv']['type'];
$tmpName = $_FILES['csv']['tmp_name'];
// check the file is a csv
if($ext === 'csv'){
if(($handle = fopen($tmpName, 'r')) !== FALSE) {
// necessary if a large csv file
set_time_limit(0);
mysqli_set_charset($connection,"utf8");
$success = 0;
$nosuccess = 0;
while(( $data = fgetcsv($handle, 1000, ',')) !== FALSE) {
// number of fields in the csv
$csv[$row]['col1'] = str_replace("'", " ", $data[0]);//orderid
$csv[$row]['col2'] = str_replace("'", " ", $data[1]);//productid
$csv[$row]['col3'] = str_replace("'", " ", $data[2]);//productdesc
if ($csv[$row]['col1']==0){
if ($csv[$row-1]['col1']!=0){
$sql = "INSERT INTO csv (orderid, orderdate, orderstatus) VALUES ('". $csv[$row-1]['col1']."','". $csv[$row-1]['col2']."','". $csv[$row-1]['col3']."')";
}
if ($csv[$row-2]['col1']!=0){
$sql = "INSERT INTO csv (orderid, orderdate, orderstatus) VALUES ('". $csv[$row-2]['col1']."','". $csv[$row-2]['col2']."','". $csv[$row-2]['col3']."')";
}
//etc
}
else
{
$sql = "INSERT INTO csv (orderid, orderdate, orderstatus) VALUES ('". $csv[$row]['col1']."','". $csv[$row]['col2']."','". $csv[$row]['col3']."')";
}
mysqli_query($connection, $sql);
}
}
}
但不起作用
