PHP fopen（$文件）$文件需要转义？

我正在努力从我的媒体服务器上获取一些id3标签。我有我发现挖掘ID3标签了MP3的

<?php 
// From here: http://www.autistici.org/ermes/index.php?pag=1&post=15 
// and fixed here: http://www.barattalo.it 
// ------------------------------ 
// example: 
// print_r(tagReader ("myfile.mp3")); 
// ------------------------------ 
function tagReader($file){ 
    $id3v23 = array("TIT2","TALB","TPE1","TRCK","TDRC","TLEN","USLT"); 
    $id3v22 = array("TT2","TAL","TP1","TRK","TYE","TLE","ULT"); 
    $fsize = filesize($file); 
    $fd = fopen($file,"r"); 
    $tag = fread($fd,$fsize); 
    $tmp = ""; 
    fclose($fd); 
    if (substr($tag,0,3) == "ID3") { 
     $result['FileName'] = $file; 
     $result['TAG'] = substr($tag,0,3); 
     $result['Version'] = hexdec(bin2hex(substr($tag,3,1))).".".hexdec(bin2hex(substr($tag,4,1))); 
    } 
    if($result['Version'] == "4.0" || $result['Version'] == "3.0"){ 
     for ($i=0;$i<count($id3v23);$i++){ 
      if (strpos($tag,$id3v23[$i].chr(0))!= FALSE){ 
       $pos = strpos($tag, $id3v23[$i].chr(0)); 
       $len = hexdec(bin2hex(substr($tag,($pos+5),3))); 
       $data = substr($tag, $pos, 9+$len); 
       for ($a=0;$a<strlen($data);$a++){ 
        $char = substr($data,$a,1); 
        if($char >= " " && $char <= "~") $tmp.=$char; 
       } 
       if(substr($tmp,0,4) == "TIT2") $result['Title'] = substr($tmp,4); 
       if(substr($tmp,0,4) == "TALB") $result['Album'] = substr($tmp,4); 
       if(substr($tmp,0,4) == "TPE1") $result['Author'] = substr($tmp,4); 
       if(substr($tmp,0,4) == "TRCK") $result['Track'] = substr($tmp,4); 

       if(substr($tmp,0,4) == "TDRC") $result['Year'] = substr($tmp,4); 
       if(substr($tmp,0,4) == "TLEN") $result['Lenght'] = substr($tmp,4); 
       if(substr($tmp,0,4) == "USLT") $result['Lyric'] = substr($tmp,7); 
       $tmp = ""; 
      } 
     } 
    } 
    if($result['Version'] == "2.0"){ 
     for ($i=0;$i<count($id3v22);$i++){ 
      if (strpos($tag,$id3v22[$i].chr(0))!= FALSE){ 
       $pos = strpos($tag, $id3v22[$i].chr(0)); 
       $len = hexdec(bin2hex(substr($tag,($pos+3),3))); 
       $data = substr($tag, $pos, 6+$len); 
       for ($a=0;$a<strlen($data);$a++){ 
        $char = substr($data,$a,1); 
        if($char >= " " && $char <= "~") $tmp.=$char; 
       } 
       if(substr($tmp,0,3) == "TT2") $result['Title'] = substr($tmp,3); 
       if(substr($tmp,0,3) == "TAL") $result['Album'] = substr($tmp,3); 
       if(substr($tmp,0,3) == "TP1") $result['Author'] = substr($tmp,3); 
       if(substr($tmp,0,3) == "TRK") $result['Track'] = substr($tmp,3); 
       if(substr($tmp,0,3) == "TYE") $result['Year'] = substr($tmp,3); 
       if(substr($tmp,0,3) == "TLE") $result['Lenght'] = substr($tmp,3); 
       if(substr($tmp,0,3) == "ULT") $result['Lyric'] = substr($tmp,6); 
       $tmp = ""; 
      } 
     } 
    } 
    return $result; 
}

和subsequest呼叫

print_r(tagReader("/mnt/data/downloads/music/Arctic Monkeys/Who The F Are Arctic Monkeys_ - EP/05 Who The F Are Arctic Monkeys_.mp3"));

的我复制该文件到一个简单的路径（甚至有空格）的方法，该方法可以正常工作。它似乎并没有处理长文件名。我试图用\逃脱空间，但那不起作用。

你得到的错误是什么？你确定这个文件是可读的吗？ –

请启用错误报告并显示：'error_reporting（-1）; ini_set（'display_errors'，1）;'然后再次处理你遇到错误的情况。我假设你会收到一条错误消息，然后你可以添加到你的问题。 – hakre

您的Web服务器的用户ID是否具有从/ mnt/data读取的权限？ –

其实我发布的评论了上面，我最终打开错误报告。有错误，我得到了Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 13484377 bytes) in /opt/share/www/hi.php on line 16所以我加了ini_set("memory_limit","20M");它修复了它

整齐的小脚本！我自己为一个流行的媒体分享网站做了一些媒体处理MP3的MP3，我们一直依靠命令行工具读取ID3标签。我从来没有得到一个脚本来阅读PHP中的标签。

无论如何，不需要转移路径。 PHP没有这样正确地将它传递给底层操作系统。

我重新创建了/mnt/data/...路径，并将我自己的MP3文件放在那里，文件名与您输入的完全相同。我还在脚本的顶部添加了error_reporting(E_ALL);来打开错误报告。该脚本没有错误，并在我的MP3文件中正确显示了ID3标签。

它在我看来，该文件不是你认为它的路径，或者你的/mnt/data挂载点有问题。你检查过这些东西吗？您可以检查是否PHP能够看到和使用以下脚本读取文件：

<?php 
    $path = "/mnt/data/downloads/music/Arctic Monkeys/Who The F Are Arctic Monkeys_ - EP/05 Who The F Are Arctic Monkeys_.mp3"; 
    if (!is_file($path)) { 
     throw new Exception("No such file"); 
    } else if (!is_readable($path)) { 
     throw new Exception("Path exists, but is not readable"); 
    } 
?>
