PHP로 비디오 파일 업로드, 저장 및 데이터베이스 추적을 자동화하는 방법은 무엇입니까?

<code class="html"><form method="post" enctype="multipart/form-data" action="/vids/file-upload.php">
    <input type="file" accept="video/*" name="filename">
    <input type="submit" value="Upload">
</form></code>

<code class="php"><?php

// Configure upload settings
$folder = $_POST["course"];
$max_file_size = 0; // 0 means no limit
$allowed_file_types = array('avi', 'mov', 'mp4');

// Get file details
$filename = $_FILES['filename']['name'];
$tmp_name = $_FILES['filename']['tmp_name'];
$file_ext = pathinfo($filename, PATHINFO_EXTENSION);

// Validate file
if (!in_array($file_ext, $allowed_file_types)) {
    echo "Only specific file types are allowed.";
} else if ($max_file_size > 0 && $_FILES['filename']['size'] > $max_file_size * 1024) {
    echo "File exceeds the maximum allowed size.";
} else {

    // Create the upload directory if it doesn't exist
    if (!file_exists($folder)) {
        mkdir($folder, 0777, true);
    }

    // Move the file to the upload directory
    $destination = $folder . '/' . $filename;
    move_uploaded_file($tmp_name, $destination);

    // Create database entry (if desired)

    // Update additional user information (if provided)
}
?></code>

<code class="php">// Connect to the database

// Prepare SQL query

// Execute query and store the new entry ID

// Close the database connection</code>
