在导入csv上跳过第一行

Question

需要添加额外的行以跳过带有csv文件头的第一行.但我不知道从哪里开始.

<?php

if(isset($_POST["submit"]))
{
$host="localhost"; // Host name.
$db_user="root"; //mysql user
$db_password=""; //mysql pass
$db='local'; // Database name.
$conn=mysql_connect($host,$db_user,$db_password) or die (mysql_error());
mysql_select_db($db) or die (mysql_error());

echo $filename=$_FILES["file"]["name"];
$ext=substr($filename,strrpos($filename,"."),(strlen($filename)-strrpos($filename,".")));

  $file = fopen($filename, "r");
    $handle = fopen("$filename", "r");
    while (($data = fgetcsv($handle, 100000, ",")) !== FALSE)
    {
    $import="INSERT into customers(fname,lname,company,address,city,state,country,postal_code,phone,email) values('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]','$data[7]','$data[8]','$data[9]')";
    mysql_query($import) or die(mysql_error());
    }
    fclose($handle);
    print "Import done";
    }
    else
    {
    print "<form enctype='multipart/form-data' method='post'>";
    print "Type file name to import:";
    print "<input type='file' name='file' id='file'>";
    print "<input type='submit' name='submit' value='submit'></form>";
    }
?>

任何帮助都是相关的.

请考虑使用SplFileObject来读的CSV文件,它支持迭代更好,例如,在与标准结合SPL LimitIterator这是小菜一碟:

$file = new SplFileObject($filename);
$file->setFlags(SplFileObject::READ_CSV);
$it = new LimitIterator($file, 1);
foreach($it as $data) {
    $mask = "INSERT INTO customers (fname, lname, company, address, city, state, country, postal_code, phone, email) values('%s','%s','%s','%s','%s','%s','%s','%s','%s','%s')";
    $sql  = vsprintf($mask, $data);
    mysql_query($sql) or die(mysql_error());
}

另外请注意:

请不要mysql_*在新代码中使用函数.它们不再维护,并且已被正式弃用.看到红色的盒子？了解准备好的语句,并使用 PDO或 MySQLi -本文将帮助您确定哪些.如果您选择PDO,这是一个很好的教程.
