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) + * 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 + * 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 (or higher) for getID3() 1.7.x (and earlier) +* PHP 5.3.0 (or higher) for getID3() 1.8.x (and up) +* PHP 5.0.0 (or higher) for getID3() 2.0.x (and up) +* at least 4MB memory for PHP. 8MB 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: + +// 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. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

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: + function getID3($filename) { return unpack('a3TAG/a30title/a30artist/a30album/a4year/a28comment/c1track/c1genreid', substr(file_get_contents($filename), -128)); } + + +Future Plans +=========================================================================== +http://www.getid3.org/phpBB3/viewforum.php?f=7 + +* Better support for MP4 container format +* Scan for appended ID3v2 tag at end of file per ID3v2.4 specs (Section 5.0) +* Support for JPEG-2000 (http://www.morgan-multimedia.com/jpeg2000_overview.htm) +* Support for MOD (mod/stm/s3m/it/xm/mtm/ult/669) +* Support for ACE (thanks Vince) +* Support for Ogg other than Vorbis, Speex and OggFlac (ie.

"The reason + it's like that is because there is no seeking support in + libOggFLAC yet, so it has no way to go back and write the + computed sum after encoding.
