Question

编辑 - 我更新了LogsModel.php以提供更好的图片。

我试图将数据插入到我的表中，其值为数组项，但数据将被插入两次。有谁知道为什么？当我运行脚本时，我的数据库插入了8行，但.txt文件中只有4行。

LogsModel.php （更新）

function __construct($db) {
    try {
        $this->db = $db;
    } catch (PDOException $e) {
        exit('Database connection could not be established.');
    }
}

public function getAllLogs()
{
    $sql = "SELECT log_date, log_id, log_time FROM log_table";
    $query = $this->db->prepare($sql);
    $query->execute();

    return $query->fetchAll();
}

public function insertFileContents()
{
    $filename = 'C:/Program Files/FileMaker/FileMaker Server/Logs/Access2.txt';

    // Open the file
    $fp = @fopen($filename, 'r');

    // Add each line to an array
    if ($fp) {
        $lines = explode("\n", fread($fp, filesize($filename)));

        foreach($lines as $line){
            $l = explode(" ", $line);
            $log_dates = $l[0];
            $log_times = $l[1];

            $sql = "INSERT INTO log_table (log_date, log_time) VALUES ('$log_dates', '$log_times')";

            $query = $this->db->prepare($sql);
            $query->execute();
        }

    }

}

LogsController.php

public function index()
{
    // load a model, perform an action, pass the returned data to a variable
    $logs_model = $this->loadModel('LogsModel');
    $line_items = $logs_model->insertFileContents();
    $logs = $logs_model->getAllLogs();

    // load views.
    require 'application/views/_templates/header.php';
    require 'application/views/home/index.php';
    require 'application/views/_templates/footer.php';
}

的index.php

<div class="container">

<table class="table table-striped">
    <tr>
        <td>Date</td>
        <td>Time</td>
    </tr>
    <?php foreach ($logs as $log) { ?>
        <tr>
            <td><?php if (isset($log->log_date)) echo (string)$log->log_date; ?></td>
            <td><?php if (isset($log->log_time)) echo (string)$log->log_time; ?></td>
        </tr>
    <?php } ?>
</table>

</div>
