getID3() by James Heinrich (<info@getid3.org>) === **Available at <http://getid3.sourceforge.net> or <http://www.getid3.org>** getID3() is released under multiple licenses. You may choose from the following licenses, and use getID3 according to the terms of the license most suitable to your project. **GNU GPL:** * [v3](https://gnu.org/licenses/gpl.html) * [v2](https://gnu.org/licenses/old-licenses/gpl-2.0.html) * [v1](https://gnu.org/licenses/old-licenses/gpl-1.0.html) **GNU LGPL:** * [v3](https://gnu.org/licenses/lgpl.html) **Mozilla MPL:** * [v2](http://www.mozilla.org/MPL/2.0/) **getID3 Commercial License:** * [gCL](http://getid3.org/#gCL) (payment required) * * * Copies of each of the above licenses are included in the `licenses/` directory of the getID3 distribution. If you want to donate, there is a link on <http://www.getid3.org> for PayPal donations. Quick Start === **Q:** How can I check that getID3() works on my server/files? **A:** Unzip getID3() to a directory, then access `/demos/demo.browse.php` Support === **Q:** I have a question, or I found a bug. What do I do? **A:** The preferred method of support requests and/or bug reports is the forum at <http://support.getid3.org/> Sourceforge Notification === It's highly recommended that you sign up for notification from Sourceforge for when new versions are released. Please visit: <http://sourceforge.net/project/showfiles.php?group_id=55859> and click the little "monitor package" icon/link. If you're previously signed up for the mailing list, be aware that it has been discontinued, only the automated Sourceforge notification will be used from now on. What does getID3() do? === Reads & parses (to varying degrees): + tags: * APE (v1 and v2) * ID3v1 (& ID3v1.1) * ID3v2 (v2.4, v2.3, v2.2) * Lyrics3 (v1 & v2) + audio-lossy: * MP3/MP2/MP1 * MPC / Musepack * Ogg (Vorbis, OggFLAC, Speex, Opus) * AAC / MP4 * AC3 * DTS * RealAudio * Speex * DSS * VQF + audio-lossless: * AIFF * AU * Bonk * CD-audio (*.cda) * FLAC * LA (Lossless Audio) * LiteWave * LPAC * MIDI * Monkey's Audio * OptimFROG * RKAU * Shorten * TTA * VOC * WAV (RIFF) * WavPack + audio-video: * ASF: ASF, Windows Media Audio (WMA), Windows Media Video (WMV) * AVI (RIFF) * Flash * Matroska (MKV) * MPEG-1 / MPEG-2 * NSV (Nullsoft Streaming Video) * Quicktime (including MP4) * RealVideo + still image: * BMP * GIF * JPEG * PNG * TIFF * SWF (Flash) * PhotoCD + data: * ISO-9660 CD-ROM image (directory structure) * SZIP (limited support) * ZIP (directory structure) * TAR * CUE + Writes: * ID3v1 (& ID3v1.1) * ID3v2 (v2.3 & v2.4) * VorbisComment on OggVorbis * VorbisComment on FLAC (not OggFLAC) * APE v2 * Lyrics3 (delete only) Requirements === * PHP 4.2.0 up to 5.2.x for getID3() 1.7.x (and earlier) * PHP 5.0.5 (or higher) for getID3() 1.8.x (and up) * PHP 5.0.5 (or higher) for getID3() 2.0.x (and up) * at least 4MB memory for PHP. 8MB or more is highly recommended. 12MB is required with all modules loaded. Usage === See /demos/demo.basic.php for a very basic use of getID3() with no fancy output, just scanning one file. See structure.txt for the returned data structure. **For an example of a complete directory-browsing, file-scanning implementation of getID3(), please run /demos/demo.browse.php** See /demos/demo.mysql.php for a sample recursive scanning code that scans every file in a given directory, and all sub-directories, stores the results in a database and allows various analysis / maintenance operations To analyze remote files over HTTP or FTP you need to copy the file locally first before running getID3(). Your code would look something like this: ``` php <?php // Copy remote file locally to scan with getID3() $remotefilename = 'http://www.example.com/filename.mp3'; if ($fp_remote = fopen($remotefilename, 'rb')) { $localtempfilename = tempnam('/tmp', 'getID3'); if ($fp_local = fopen($localtempfilename, 'wb')) { while ($buffer = fread($fp_remote, 8192)) { fwrite($fp_local, $buffer); } fclose($fp_local); // Initialize getID3 engine $getID3 = new getID3; $ThisFileInfo = $getID3->analyze($filename); // Delete temporary file unlink($localtempfilename); } fclose($fp_remote); } ``` **See /demos/demo.write.php for how to write tags.** What does the returned data structure look like? === See structure.txt It is recommended that you look at the output of /demos/demo.browse.php scanning the file(s) you're interested in to confirm what data is actually returned for any particular filetype in general, and your files in particular, as the actual data returned may vary considerably depending on what information is available in the file itself. Notes === getID3() 1.x: --- If the format parser encounters a critical problem, it will return something in `$fileinfo['error']`, describing the encountered error. If a less critical error or notice is generated it will appear in `$fileinfo['warning']`. Both keys may contain more than one warning or error. If something is returned in ['error'] then the file was not correctly parsed and returned data may or may not be correct and/or complete. If something is returned in `['warning']` (and not `['error']`) then the data that is returned is OK - usually getID3() is reporting errors in the file that have been worked around due to known bugs in other programs. Some warnings may indicate that the data that is returned is OK but that some data could not be extracted due to errors in the file. getID3() 2.x: --- See above except errors are thrown (so you will only get one error). Disclaimer === getID3() has been tested on many systems, on many types of files, under many operating systems, and is generally believe to be stable and safe. That being said, there is still the chance there is an undiscovered and/or unfixed bug that may potentially corrupt your file, especially within the writing functions. By using getID3() you agree that it's not my fault if any of your files are corrupted. In fact, I'm not liable for anything :) License === GNU General Public License - see license.txt This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

FAQ: --- **Q:** Can I use getID3() in my program? Do I need a commercial license? **A:** You're generally free to use getID3 however you see fit. The only case in which you would require a commercial license is if you're selling your closed-source program that integrates getID3. If you sell your program including a copy of getID3, that's fine as long as you include a copy of the sourcecode when you sell it. Or you can distribute your code without getID3 and say "download it from getid3.sourceforge.net" Why is it called "getID3()" if it does so much more than just that? === v0.1 did in fact just do that. I don't have a copy of code that old, but I could essentially write it today with a one-line function: ```
