导入CSV,排除第一行

Question

我现在正在导入我的csv,除了一件事,如何让导入忽略第一行中的数据？员工将上载第一行中具有列名称的相同格式.

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 tictoc(employee,taskname,tasktime,sessiontime,sessionstart,sessionend,sessionnotes) values('" . $userinfo['first_name'] . " " . $userinfo['last_name'] . "','$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]')";

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

    fclose($handle);

    print "Import done";
}

只需设置一个变量$i = 0 然后只插入一个$i = 1或多个

if (isset($_POST['submit'])) {
    $i=0; //so we can skip first row

    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) {
        if($i>0) {
            $import="INSERT into tictoc(employee,taskname,tasktime,sessiontime,sessionstart,sessionend,sessionnotes) values('".$userinfo['first_name']." ".$userinfo['last_name']."','$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]')";

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

    fclose($handle);

    print "Import done";
}

您可以简单地使用MySQL的LOAD DATA INFILE命令,这比将CSV解析为PHP 要快得多,INSERT为每条记录构建一个语句,将其作为字符串提交给MySQL并让MySQL解析SQL的字符串(存在SQL注入的风险):

LOAD DATA INFILE ? INTO TABLE tictoc
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
IGNORE 1 LINES
(tasktime, sessiontime, sessionstart, sessionend, sessionnotes)
SET employee = ?, taskname = ?

使用PDO:

$dbh = new PDO('mysql:dbname='.$dbname, $username, $password);

if (is_uploaded_file($_FILES['filename']['tmp_name'])) {
  $qry = $dbh->prepare('
    LOAD DATA INFILE :filepath INTO TABLE tictoc
    FIELDS TERMINATED BY \',\' OPTIONALLY ENCLOSED BY \'"\'
    IGNORE 1 LINES
    (tasktime, sessiontime, sessionstart, sessionend, sessionnotes)
    SET employee = :employee, taskname = :taskname
  ');

  $qry->execute(array(
    ':filepath' => $_FILES['filename']['tmp_name'],
    ':employee' => $userinfo['first_name'],
    ':taskname' => $userinfo['last_name']
  ));
}
