下载文件时更新数据库[PHP]

现在的问题是如何为下载的文件分配一个id（从上一页获取）并更新数据库中的文件地址以将其提供给用户？

希望这对您有用

<?php
$id = $_GET['id'];      
$url = $_POST['vidurl'];
$cmd = 'youtube-dl -o /downloads/%(title)s.%(ext)s '. escapeshellarg($url);
$exec = shell_exec($cmd);
?>

希望这对你有用

<?php
$id = $_GET['id'];      
$url = $_POST['vidurl'];
$cmd = 'youtube-dl -o /downloads/%(title)s.%(ext)s '. escapeshellarg($url);
$exec = shell_exec($cmd);
?>

<?php
//first solution

$id = $_GET['id'];      
$url = $_POST['vidurl'];
$cmd = 'youtube-dl -o /downloads/'.$id.'_%(id)s.%(ext)s '. escapeshellarg($url);
$output = shell_exec($cmd);

//second solution

//print_r($output); will give you the following output

foreach($output as $key => $value) {
    if(strpos($value, 'destination') === false) {
        // download failed or some error message
    } else {
        $destination = explode(':', $value)[1]; //full path with file id and extension
        //rename your file here here
        //$rename = rename($destination, $newdesitination);
        //insert in database
    }
}
?>

output: array (
  0 => '[youtube] Setting language',
  1 => '[youtube] XCj-wJB5j4c: Downloading video webpage',
  2 => '[youtube] XCj-wJB5j4c: Downloading video info webpage',
  3 => '[youtube] XCj-wJB5j4c: Extracting video information',
  4 => '[download] Destination: /downloads/YourID_XCj-wJB5j4c.flv',
