我想要做的就是使用PHP來執行youtube-dl -x --audio-format mp3 "token"並獲得以下參數JSON：從PHP代碼中執行shell腳本
- 狀態（錯誤= 0 /成功= 1）
- 保存的文件URL （您將在控制檯結果示例中看到它：
[avconv] Destination: Jennifer Lopez - Booty ft. Iggy Azalea-nxtIRArhVD4.mp3）
這是我寫的PHP代碼。
<?php
if ($_GET["token"]) {
$url = $_GET["token"];
$template = '/home/website/public_html/%(id)s.%(ext)s';
$string = ('youtube-dl -x --audio-format mp3 ' . escapeshellarg($url) . ' ' . escapeshellarg($template));
$descriptorspec = array(
0 => array("pipe", "r"), // stdin
1 => array("pipe", "w"), // stdout
2 => array("pipe", "w"), // stderr
);
$process = proc_open($string, $descriptorspec, $pipes);
$stdout = stream_get_contents($pipes[1]);
fclose($pipes[1]);
$stderr = stream_get_contents($pipes[2]);
fclose($pipes[2]);
$ret = proc_close($process);
echo json_encode(array('status' => $ret, 'errors' => $stderr,
'url_orginal' => $url, 'output' => $stdout,
'command' => $string));
}
?>
基本上它執行
youtube-dl -x --audio-format mp3 "token"
當我在控制檯執行相同的命令（通過SSH），我得到這樣的

結果當我在PHP環境中執行相同的命令越來越關注json結果

事實上，PHP做的工作和保存文件，但輸出不相同，我無法獲得目標文件的網址。
我在做什麼錯？有什麼建議麼？
