php - 将 CSV 导入数据库，插入而不截断表

Question

我这里有这段代码，它允许我将数据从 csv 文件导入数据库，现在它所做的是在插入之前截断表，我之前尝试删除截断表但后来它不会'传递数据。我的意思是我怎样才能在这里修改这段代码？我只需要它来插入数据，而不需要清空当前表!

谢谢..

$deleterecords = "TRUNCATE TABLE imovo"; //empty the table of its current records
mysql_query($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) {
        $import="INSERT into imovo(date,time,location,rbpos_id,mobile_number) values('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]')";

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

    fclose($handle);

    print "Import done";

    //view upload form
}else {


}

“我之前尝试删除截断表，但它不会传递数据。”

可能是因为您有唯一索引并尝试插入重复记录。
