php - 使用 PHP 将 TXT 文件中的行插入 SQL 数据库

Question

我有一个包含来自设备的数据的文件，我需要将此数据插入到数据库中。文本文件如下所示:

10/01/15-20:37:30 = 40.2,25.4,42.3,54.3,70.0,66.6
10/01/15-20:38:26 = 67.3,18.4,30.6,39.3,70.0,66.6
10/01/15-20:39:21 = 74.5,16.8,28.2,36.0,70.0,66.6
10/01/15-20:40:16 = 76.8,16.6,27.6,35.2,70.0,66.6
10/01/15-20:41:12 = 78.1,16.4,27.3,34.9,70.0,66.6

我的代码目前如下所示:

<?php
    $servername = "localhost";
    $username = "root";
    $password = "pass";
    $dbname = "dbase";


    // Create connection
    $conn = new mysqli($servername, $username, $password, $dbname);
    // Check connection
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    } 
?>

<?PHP

    $file_handle = fopen("datalog.txt", "r");

    while (!feof($file_handle) ) {

    $line_of_text = fgets($file_handle);
    $parts = explode('  ', $line_of_text);

    print $parts[0] . $parts[1]. "<BR>";

}

$datainsert = "INSERT INTO reading (val1, val2, val3, val4, val5, val6, val7, val8, val9, val10) VALUES ($parts[0])"; 

if (mysqli_query($conn, $datainsert)) {
    echo "New record created successfully";
} else {
    echo "Error: " . $datainsert . "<br>" . mysqli_error($conn);
}


?>

<?php
$conn->close();
?>

我得到的错误是这样的:

Error:

INSERT INTO reading (Box_ID, Time_Stamp, Temperature, Humidity, CO_Level, VOC_Reading_UOM, VOC_Reading_V1, VOC_Reading_V2, VOC_Reading_V3, VOC_Reading_V4) VALUES () Column count doesn't match value count at row 1

我的数据库和站点连接没有错误，并且此页面是唯一有问题的页面。出了什么问题？

您似乎因包含两个空格的字符串而爆炸。然而，在您的文本文件中，您的“字段”由一个空格分隔。您应该更改对 explode() 的调用以使用单个空格(或者看看 preg_split())。
