Question

我猜你不必查看整个代码，但无论如何我都会包含它。

<?php if (!$_POST) { ?>
<!DOCTYPE html>
<html>

<div class="header">
  <img src="images/logo.png" alt="logo" />

</div>

<body background="images/background.png" >

        <form action="" method="post" enctype="multipart/form-data">
            Choose your file: <br /> 
            <input name="csv" type="file" id="csv" /> <br /> <br /> 
            <input type="submit" name="Submit" value="Submit" /> 
        </form>
    </body>
</html>
<?php
} else {
$connect = new mysqli("localhost", "username", "password", "csvdb");
if ($_FILES['csv']['size'] > 0) {
    //get the csv file 
    $file = $_FILES['csv']['tmp_name']; 
    $handle = fopen($file, "r");
    $i = 0;
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        if ($i > 0) {
$import = "INSERT into csvtb(project_id,unit_id,phase,building,level,orientation,apartment_type,size,garden,garden_and_terrace_size,bedrooms,parking,floorplan,sold) values('$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]','$data[7]','$data[8]','$data[9]','$data[10]''$data[11]','$data[12]','$data[13],'$data[14])";
            $connect->query($import);
        }
        $i++;
    }
    fclose($handle);
    print "Import done";
}
}
?>

错误在第30行，未定义的偏移量

$import = "INSERT into csvtb(project_id,unit_id,phase,building,level,orientation,apartment_type,size,garden,garden_and_terrace_size,bedrooms,parking,floorplan,sold) values('$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]','$data[7]','$data[8]','$data[9]','$data[10]''$data[11]','$data[12]','$data[13],'$data[14])";
            $connect->query($import);

我使用许多php在线检查工具检查了我的代码，他们说代码很干净。我想我知道错误是什么，我猜是因为我没有插入索引0，因为我希望它是我的数据库的id。我不确定，如果我是，我不会问。我的PHP技能并不是那么好。

CSV中的某些行可能比提供给查询的数据少。我建议以可以记录/调试的方式处理它。

使用您的示例代码，如果未发现数据有效，我刚刚完成了一些早期退出。您可以应用相同类型的逻辑并打印出不具有总共15个数组元素的行。看来你正在跳过元素0并选择1..14。那绝对没问题;只需检查以确保所有行都为您提供15个数组元素。

<?php 
if ($_POST) 
{
    $connect = new mysqli("localhost", "username", "password", "csvdb");
    if ($_FILES['csv']['size'] > 0) 
    {
        //get the csv file 
        $file = $_FILES['csv']['tmp_name']; 
        $handle = fopen($file, "r");

        $i = 0;
        $expected_array_count = 15;

        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) 
        {
            // skip first line
            if ($i == 0) { i++; continue; }

            // print offending line and continue to the next line 
            // if array does not have the expected count
            if (count(data) !== $expected_array_count) 
            {
                echo sprintf("Line %d has %d lines; %d expected: %s",
                    $i+1,
                    count(data),
                    $expected_array_count,
                    implode("~~", $array)
                );

                i++;
                continue;
            }

            performImport($data);
            $i++;
        }
        fclose($handle);
        print "Import done";
    }
<?php
}

else 
{
    <!DOCTYPE html>

            </form>
        </body>

}


// function does the importing
function performImport($data)
{
    global $connect;

    // instead of entering data like this, there are 
    // better alternatives
    $import = "
    INSERT into csvtb
    (
        project_id,unit_id,phase,
        building,level,orientation,
        apartment_type,size,garden,

        '$data[10]','$data[11]','$data[12]',
        '$data[13]','$data[14]'
    )";

    // one alterate
    // $import = sprintf("insert into ... values (%d, %s, %d...)", $data[1], $data[2] ...)

    // another alternate (http://php.net/manual/en/mysqli-stmt.bind-param.php)
    // $import = "insert into ... values (?, ?, ...)"
    // mysqli_stmt_bind_param($import, 'sss...', $data[1], $data[2]...);

    // yet another alternate: use PDO
    $connect->query($import);
}
?>

PHP：从csv
