Handy PHP script to add the .mp3 extension to your MP3s

[Fahrvergnuugen]

If you're like me...in the old days you took the extension off of all of your mp3s so that you had more available characters to name the file something intelligent [thanks to the limit of 32 character file names in os9].

So I had a few thousand mp3s laying around that didn't have the mp3 extension and a few more thousand that did have the extension.

So I wrote this script to add .mp3 to all of the files in a given folder that do not already have an extension. It works recursively, so it doesn't matter how your music dir is setup.


Its setup to do a "test" run first, check everything over and make sure its not going to fubar your music collection! BACK EVERYTHING UP FIRST, I dont want to hear it if something goes terribly wrong and you loose all 568,689 of your MP3s.

<?
// Give the absolute path to your music folder
$mp3_path = '/path/to/your/music/folder/';

// This is to stop the script from being executed until you look in here and set it up right
die("i\'m broken, edit this script");

echo "START<br>\n";
$mp3s = GetDirectoryArray(array(), $mp3_path, 0);
echo "\n<br>END";

function GetDirectoryArray($listing, $directory, $count){
      $dummy = $count;

      if($handle = opendir($directory)){
            while($file = readdir($handle)){
            	  //ignore the . and .. dirs
                  if ($file=='.' || $file=='..'){
                        continue;
                  }elseif($h = @opendir($directory.$file."/")){
                        closedir($h);
                        $count = -1;
                        $listing["$file"] = array();
                        GetDirectoryArray(&$listing["$file"],$directory.$file."/", $count + 1);
                  }else{
                        $listing[$dummy] = $file;
                        $dummy = $dummy + 1;

                        if(!preg_match("/.mp3$/",$file) && !preg_match("/(.DS_Store|.FBCIndex|.FBCLockFolder|.FBCSemaphoreFile)/",$file)){
                            $path = $directory.$file;
                            
                            // Comment the next line out when you are ready to actually rename your files
                            echo '<b>rename </b>'.$path.' <b>to</b> '.$path.".mp3<br>\n"; 
                        	
                        	// Uncomment the following IF statement when you're ready to actually rename
                        	//if(!rename($path,$path.".mp3")){
                        	//	echo '<font color="#FF0000">error: '.$path."</font><br>\n";
                        	//}
                        	
                        	$counter++;
                        }
                  }
            }
      }

      closedir($handle);
      return ($listing);
