我想将 CSV 文件中的数据插入 MySQL 表。为此，我现在使用以下代码，但是当我上传文件时，我的浏览器变得没有响应。几次之后，会弹出一个显示重启 Firefox 或退出 Firefox。我只是想知道，我在给定代码中的错误在哪里？

从 CLI 而不是浏览器运行它怎么样？

Please try this I have provide some php code for import data csv format 
<body>
<div id="container">
<div id="form">

<?php
$deleterecords = "TRUNCATE TABLE tablename"; //empty the table of its current records
mysql_query($deleterecords);

//Upload File
if (isset($_POST['submit'])) {

    if (is_uploaded_file($_FILES['filename']['tmp_name'])) {
        echo "<h1>" . "File ". $_FILES['filename']['name'] ." uploaded 
 successfully." . "</h1>";
        echo "<h2>Displaying contents:</h2>";
        readfile($_FILES['filename']['tmp_name']);
    }

    //Import uploaded file to Database
    $handle = fopen($_FILES['filename']['tmp_name'], "r");

    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $import="INSERT into importing(text,number)values('$data[0]','$data[1]')";

        mysql_query($import) or die(mysql_error());
    }

    fclose($handle);

    print "Import done";

//view upload form
} else {

    print "Upload new csv by browsing to file and clicking on Upload<br />\n";

    print "<form enctype='multipart/form-data' action='upload.php' method='post'>";

    print "File name to import:<br />\n";

    print "<input size='50' type='file' name='filename'><br />\n";

    print "<input type='submit' name='submit' value='Upload'></form>";

}

?>

</div>
</div>

您想要更多的描述请使用这个链接stackoverflow.com/questions/11448307/…

【解决方案2】：

我觉得你没有在这里建立数据库连接。正确检查你的数据库连接

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// 创建连接

$conn = new mysqli($servername, $username, $password,$dbname);

在此处删除评论// $tmp = explode(".",$image);

它工作正常>>检查此链接coyotelab.org/php/…
首先建立数据库连接>>
//上传文件 if (isset($_POST['submit'])) { if (is_uploaded_file($_FILES['filename']['tmp_name'])) { echo "
” 。 “文件 ”。 $_FILES['filename']['name'] ."上传成功。" . "
"; echo "
显示内容：
"; readfile($_FILES['filename']['tmp_name']); } //将上传的文件导入数据库 $handle = fopen($_FILES['filename']['tmp_name'], "r"); while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $import="INSERT into users(firstname,lastname) values('$data[0]','$data[ 1]')"; mysql_query($import) 或死(mysql_error()); }
fclose($handle);打印“导入完成”； //查看上传表单 }else { print "通过浏览到文件并点击上传来上传新的 csv
\n"; print "
"; print "要导入的文件名：
\n";
print "
\n"; print ""; } ?>

” 。 “文件 ”。 $_FILES['filename']['name'] ."上传成功。" . "
