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？员工将上传第一行中具有列名的相同格式。

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$i = 0然后只在$i = 1或更多

时插入 
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，它将considerably faster比将CSV解析为PHP，为每条记录构建INSERT语句，将其作为字符串提交给MySQL和有MySQL解析SQL的字符串（有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']
  ));
}

如果您愿意，也许可以使用这种方式：

$i=0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $i++;
    if($i==1) continue;

    $import="INSERT into tictoc(employee,taskname,tasktime,sessiontime,sessionstart,sessionend,sessionnotes) values('".$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());
}

无需变量。它比这简单得多。这是一个需要最少量外国代码的解决方案，并且工作得很好。试试看：

$headers = fgetcsv($handle, 1000, ",");

在你的while（）循环之前抓取CSV数据。这会抓住标题，但不会将它们插入数据库中。 while循环开始后，第一行已经返回，因此将它们从mysql插入中删除。除此之外，似乎需要标题，因此这也解决了这个问题。

所以最后，

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");

    //Grab the headers before doing insertion
    $headers = fgetcsv($handle, 1000, ",");

    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";
}

你可以试试这个：

array_shift($data);

我已经实现了这段代码，它是经过测试的代码。我认为这是非常充分的使用

您遵循一些规则： -

1.您的csv文件根据数据库表名称（例如：db表名是用户，那么csv应该是users.csv）

2.开始输入数据后，你的csv文件的第一行应该是db表字段名称（例如：Id，name等）

3.您可以从以下网址下载数据源类： - http://code.google.com/p/php-csv-parser/因为我需要在代码下方：require_once'CSV / DataSource.php'; 

<?php
ini_set('memory_limit','512M');
$dbhost = "localhost";
$dbname = "excel_import";
$dbuser = "root";
$dbpass = "";

$conn=mysql_connect ($dbhost, $dbuser, $dbpass) or die ("I cannot connect to the database because: " . mysql_error());
mysql_select_db($dbname) or die("Unable to select database because: " . mysql_error());


require_once 'CSV/DataSource.php';


$filename = "users.csv";
$ext = explode(".",$filename);
$path = "uploads/".$filename;

$dbtable = $ext[0];

import_csv($dbtable, $path);


function import_csv($dbtable, $csv_file_name_with_path)
{
    $csv = new File_CSV_DataSource;
    $csv->load($csv_file_name_with_path);

    $csvData = $csv->connect();

    $res='';
    foreach($csvData  as $key)
    {
        $myKey ='';
        $myVal='';
        foreach($key as $k=>$v)
        {
            $myKey .=$k.',';
            $myVal .="'".$v."',";
          }

        $myKey = substr($myKey, 0, -1);
        $myVal = substr($myVal, 0, -1); 
        $query="insert into ".$dbtable." ($myKey)values($myVal)";
        $res=  mysql_query($query);

    }

    if($res ==1)
    {

                echo "record successfully Import.";

    }else{

                echo "record not successfully Import.";
    }
}

在while循环

之前声明一个变量 
$row=1;

然后在while循环中放置此条件

if($row==1){
   $row++; 
   continue;
}

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");
fgetcsv($handle); //skip the reading of the first line from the csv file

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";

}
