好吧,所以我在这个网站的某个地方找到了它,我尝试了一下,但这只是在控制台上塞满了很多错误,我没有弄错我在做什么

<?php
set_time_limit(0);
$dirPath = "masked on purpose";
$songCode = $_REQUEST['c'];
$filePath = $dirPath . "/" . $songCode . ".mp3";
$bitrate = 128;
$strContext=stream_context_create(
     array(
         'http'=>array(
         'method'=>'GET',
         'header'=>"Accept-language: en\r\n"
         )
     )
 );


 header('Content-type: audio/mpeg');
 header ("Content-Transfer-Encoding: binary");
 header ("Pragma: no-cache");
 header ("icy-br: " . $bitrate);

 $fpOrigin=fopen($filePath, 'rb', false, $strContext);
 while(!feof($fpOrigin)){
   $buffer=fread($fpOrigin, 4096);
   echo $buffer;
   flush();
 }
 fclose($fpOrigin);
 ?>

Error log

我要做的是制作一个在线广播流,该流扫描一个文件夹,并循环其中的所有.mp3文件

此处的修改: 我已将脚本更改为这样

<?php
set_time_limit(0);
$dirPath = "...";
$bitrate = 128;
$strContext=stream_context_create(
     array(
         'http'=>array(
         'method'=>'GET',
         'header'=>"Accept-language: en\r\n"
         )
     )
 );


 header('Content-type: audio/mpeg');
 header ("Content-Transfer-Encoding: binary");
 header ("Pragma: no-cache");
 header ("icy-br: " . $bitrate);
$list = scandir($dirPath);
foreach($list as $file)
{
    if($file== '.' or $file== '..')
        continue; // skip, not a file or a folder

    if(is_dir($file))
        continue; // skip, not a file

    echo $file . "<br>";
    // define the file path
    $filePath = $dirPath . '/' . $file;
    // read the file
    $fh = fopen($filePath, "r") or die("Could not open file.");
    if ($fh) {
        while (!feof($fh)) {
            $buffer = fgets($fh, 4096);
            echo $buffer;
            flush();
       }
       fclose($fh);
    }
}
?>

代码工作正常,但是问题是我希望流即使在没有人在听的情况下也能继续播放,每次有人尝试听它时,它都会重新启动。

fopen函数会将资源返回到打开的文件,如果失败则返回FALSE布尔值。看来您的文件无法打开。检查$filePath是否正确,并且$songCode是否有值。

以下是读取文件夹中所有文件的代码:

// get a list of all files/folders in a path
$list = scandir($dirPath);

foreach($list as $file)
{
    if($file== '.' or $file== '..')
        continue; // skip, not a file or a folder

    if(is_dir($file))
        continue; // skip, not a file

    // define the file path
    $filePath = $dirPath . '/' . $file;

    // read the file
    $fh = fopen($filePath, "r") or die("Could not open file.");
    if ($fh) {
        while (!feof($fh)) {
            $buffer = fgets($fh, 4096);
            // Do something with the buffer here...
       }
       fclose($fh);
    }
}
