我正在尝试导入 CSV 文件。由于我们使用的程序，第一行基本上是我想跳过的所有标题，因为我已经通过 HTML 放入了自己的标题。如何让代码跳过 CSV 的第一行？（strpos 命令是把所有行的第一个字段截掉。）

<?php
$row = 1;
if (($handle = fopen("ptt.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $num = count($data);
           $row++;
    for ($c=0; $c < $num; $c++) {
    if(strpos($data[$c], 'Finished') !== false) {
    $c++;
echo "<TR> <TD nowrap>" . $data[$c] . "</ TD>"; }
    Else{
        echo "<TD nowrap>" .  $data[$c] . "</ TD>";
        }
    }
}
fclose($handle);
}
?>

Rather than using if condition for checking whether it is the first row, a better solution is to just add an extra line of code before the line from where the while loop starts as shown below :

....
.....
fgetcsv($handle);//Adding this line will skip the reading of th first line from the csv file and the reading process will begin from the second line onwards
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
.......
.......

It is just as simple......

由于您无论如何都在跟踪行号，因此您可以使用continue跳过第一行的其余循环。

例如，在你的 while 循环开始处添加这个（就在上面$num = count($data)）：

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

还有其他方法可以做到这一点，但只要确保当你继续时，$row它仍在递增，否则你会得到一个无限循环！

把它放在你的while循环中：

if ($row == 1) continue;

请使用以下代码行

$flag = true;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
if($flag) { $flag = false; continue; }
//your code for insert
}

将 flag 变量设置为 true 并将其设置为 false 将跳过 CSV 文件的第一行。这很简单，也很容易实现。

while在上面的循环体中添加$row++;：

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

$count = 0;
while (($fields = fgetcsv($handle, 0, ",")) !== FALSE) {
    $count++;
    if ($count == 1) { continue; }

这对我有用：

$count = 0;

while(! feof($file))

      {

          $entry = fgetcsv($file, 0, ';');

          if ($count > 0) {
          //skip first line, header


          }

      $count++;
}

使用此代码 

// mysql hostname
$hostname = 'localhost';
// mysql username
$username = 'root';
// mysql password
$password = '';

if (isset($_FILES['file']))
{   

// get the csv file and open it up
$file = $_FILES['file']['tmp_name'];
//$handle is a valid file pointer to a file successfully opened by fopen(), popen(), or fsockopen(). 
$handle = fopen($file, "r"); 
    try { 
    // Database Connection using PDO
    $dbh = new PDO("mysql:host=$hostname;dbname=clasdb", $username, $password);
    // prepare for insertion
    $STM = $dbh->prepare('INSERT INTO statstrackertemp (ServerName, HiMemUti, AvgMemUti, HiCpuUti, AvgCpuUti, HiIOPerSec, AvgIOPerSec, HiDiskUsage, AvgDsikUsage) VALUES (?, ?, ?, ?, ?,?, ?, ?, ? )');



        if ($handle !== FALSE) 
        {
            // fgets() Gets a line from file pointer and read the first line from $handle and ignore it.   
            fgets($handle);
            // created loop here
            while (($data = fgetcsv($handle, 1000, ',')) !== FALSE)
            {
            $STM->execute($data);
            }       

            fclose($handle);

        }

    } 
    catch(PDOException $e)
    {
    die($e->getMessage());
    }

echo 'Data imported'; 

}
else 
{
echo 'Could not import Data';
}
