导入CSV，排除第一行

Question

我现在导入我的CSV很好，除了一件事情，我如何获得导入忽略第一行中的数据？员工将上传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"; 
} 

Answer 1

只是设置一个变量$i = 0那么只有插入时$i = 1以上

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"; 
}

你可以试试这个：

array_shift($data); 

Answer 3

也许你可以，如果你喜欢用这样的方式：

$i=0; 
while (($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()); 
} 

Answer 4

我已经实现了这个代码，它是测试代码。我觉得这是非常使用全

你必须遵循一些规则： -

贵国的CSV文件根据数据库表名（例如：数据库表名用户，那么CSV应该users.csv）

2.您的CSV文件的第一行应该是数据库表字段名（例如：ID，姓名等）后，开始您的数据录入

3.you可以下载数据源类来源： - http://code.google.com/p/php-csv-parser/，因为我有以下要求代码：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."; 
    } 
}

您可以简单地使用MySQL的LOAD DATA INFILE命令，这将是considerably faster比解析CSV到PHP，构建INSERT声明对每条记录，提交其作为一个字符串到MySQL，并具有MySQL的解析说字符串SQL（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'] 
)); 
} 

Answer 6

没有变量需要。这比这更简单。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。尝试推出：

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

在获取CSV数据的while（）循环之前。这抓住了标题，但是没有将它们插入到数据库中。一旦while循环开始，第一行已经被返回，因此不在mysql插入中。最重要的是它似乎需要标题，所以这也解决了这个问题。

到底

所以，

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"; 
} 

Answer 7

声明一个变量之前while循环

$row=1; 

然后在while循环把这个条件

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