Question

这是我导入csv数据时使用的代码，但是如何从第2行开始导入数据呢？由于第一行是列名称(ID,Student Name,Subject Code,Subject Name,Unit,Grade)。

if (isset($_POST["submitgrade"])){
if ($_FILES["file"]["name"]){
    $filename = explode('.',$_FILES["file"]["name"]);
    if ($filename[1] == 'csv')
        $handle = fopen($_FILES["file"]["tmp_name"], "r");
    while ($data = fgetcsv($handle))
    {
        $item1 = mysqli_real_escape_string($con, $data[0]);
        $item2 = mysqli_real_escape_string($con, $data[1]);
        $item3 = mysqli_real_escape_string($con, $data[2]);
        $item4 = mysqli_real_escape_string($con, $data[3]);
        $item5 = mysqli_real_escape_string($con, $data[4]);
        $item6 = mysqli_real_escape_string($con, $data[5]);
        $grade = "INSERT into subj (username,name,code,title,unit,grade) values ('$item1','$item2','$item3','$item4','$item5','$item6')";
        mysqli_query($con,$grade);
    }
    fclose($handle);
    echo 'Upload Grade Success';
}}

Answer 1

在while循环开始迭代CSV文件之前，写一次语句$data = fgetcsv($handle)。然后按原样启动循环。循环将从CSV文件的第2行开始。

您只需添加计数器和变量即可轻松访问。在这种情况下，$ startAtLine将从第1行开始。

<?php
if (isset($_POST["submitgrade"])){
    if ($_FILES["file"]["name"]){

        //These two lines are added
        $startAtLine = 0;
        $counter = 0;

        $filename = explode('.',$_FILES["file"]["name"]);
        if ($filename[1] == 'csv')
            $handle = fopen($_FILES["file"]["tmp_name"], "r");
        while ($data = fgetcsv($handle))
        {
            if(++$counter<$startAtLine)
                continue;
            $item1 = mysqli_real_escape_string($con, $data[0]);
            $item2 = mysqli_real_escape_string($con, $data[1]);
            $item3 = mysqli_real_escape_string($con, $data[2]);
            $item4 = mysqli_real_escape_string($con, $data[3]);
            $item5 = mysqli_real_escape_string($con, $data[4]);
            $item6 = mysqli_real_escape_string($con, $data[5]);
            $grade = "INSERT into subj (username,name,code,title,unit,grade) values ('$item1','$item2','$item3','$item4','$item5','$item6')";
            mysqli_query($con,$grade);
        }
        fclose($handle);
        echo 'Upload Grade Success';
    }}
?>
