跳过CSV文件的第一行

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要跳过的所有标题,因为我已经将自己的标题放在via HTML中。如何让代码跳过CSV的第一行? (strpos命令用于切断所有行中的第一个字段。)

<?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);
}
?>

不是使用if条件来检查它是否是第一行,更好的解决方案是在while循环开始的行之前添加额外的代码行,如下所示:

....
.....
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) {
.......
.......

就这么简单......

正如您要跟踪行号一样,您可以使用continue跳过第一行的其余循环。

例如,在while循环的开头添加它(在$num = count($data)上方):

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仍在增加,否则你将获得无限循环!

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变量设为true并将其设置为false将跳过CSV文件的第一行。这很简单,易于实现。

while

上方$row++;循环的正文中添加此内容
if ($row == 1) {
    continue;
}

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

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';
}
