155:
156: Usage
157: ===========================================================================
158:
159: See /demos/demo.basic.php for a very basic use of getID3() with no
160: fancy output, just scanning one file.
161:
162: See structure.txt for the returned data structure.
163:
164: *> For an example of a complete directory-browsing, <*
165: *> file-scanning implementation of getID3(), please run <*
166: *> /demos/demo.browse.php <*
167:
168: See /demos/demo.mysql.php for a sample recursive scanning code that
169: scans every file in a given directory, and all sub-directories, stores
170: the results in a database and allows various analysis / maintenance
171: operations
172:
173: To analyze remote files over HTTP or FTP you need to copy the file
174: locally first before running getID3(). Your code would look something
175: like this:
176:
177: // Copy remote file locally to scan with getID3()
178: $remotefilename = 'http://www.example.com/filename.mp3';
179: if ($fp_remote = fopen($remotefilename, 'rb')) {
180: $localtempfilename = tempnam('/tmp', 'getID3');
181: if ($fp_local = fopen($localtempfilename, 'wb')) {
182: while ($buffer = fread($fp_remote, 8192)) {
183: fwrite($fp_local, $buffer);
184: }
185: fclose($fp_local);
186:
187: // Initialize getID3 engine
188: $getID3 = new getID3;
189:
190: $ThisFileInfo = $getID3->analyze($filename);
191:
192: // Delete temporary file
193: unlink($localtempfilename);
194: }
195: fclose($fp_remote);
196: }
197:
198:
199: See /demos/demo.write.php for how to write tags.
200:
201:
202:
203: What does the returned data structure look like?
204: ===========================================================================
205:
206: See structure.txt
207:
208: It is recommended that you look at the output of
209: /demos/demo.browse.php scanning the file(s) you're interested in to
210: confirm what data is actually returned for any particular filetype in
211: general, and your files in particular, as the actual data returned
212: may vary considerably depending on what information is available in
213: the file itself.
214:
215:
216:
217: Notes
218: ===========================================================================
219:
220: getID3() 1.x:
221: If the format parser encounters a critical problem, it will return
222: something in $fileinfo['error'], describing the encountered error. If
223: a less critical error or notice is generated it will appear in
224: $fileinfo['warning']. Both keys may contain more than one warning or
225: error. If something is returned in ['error'] then the file was not
226: correctly parsed and returned data may or may not be correct and/or
227: complete. If something is returned in ['warning'] (and not ['error'])
228: then the data that is returned is OK - usually getID3() is reporting
229: errors in the file that have been worked around due to known bugs in
230: other programs. Some warnings may indicate that the data that is
231: returned is OK but that some data could not be extracted due to
232: errors in the file.
233:
234: getID3() 2.x:
235: See above except errors are thrown (so you will only get one error).
236:
237:
238:
239: Disclaimer
240: ===========================================================================
241:
242: getID3() has been tested on many systems, on many types of files,
243: under many operating systems, and is generally believe to be stable
244: and safe. That being said, there is still the chance there is an
245: undiscovered and/or unfixed bug that may potentially corrupt your
246: file, especially within the writing functions. By using getID3() you
247: agree that it's not my fault if any of your files are corrupted.
248: In fact, I'm not liable for anything :)

273: FAQ:
274: Q: Can I use getID3() in my program? Do I need a commercial license?
275: A: You're generally free to use getID3 however you see fit. The only
276: case in which you would require a commercial license is if you're
277: selling your closed-source program that integrates getID3. If you
278: sell your program including a copy of getID3, that's fine as long
279: as you include a copy of the sourcecode when you sell it. Or you
280: can distribute your code without getID3 and say "download it from
281: getid3.sourceforge.net"
282:
283:
284:
285: Why is it called "getID3()" if it does so much more than just that?
286: ===========================================================================
287:
288: v0.1 did in fact just do that. I don't have a copy of code that old, but I
289: could essentially write it today with a one-line function:
290: function getID3($filename) { return unpack('a3TAG/a30title/a30artist/a30album/a4year/a28comment/c1track/c1genreid', substr(file_get_contents($filename), -128)); }

375: Known Bugs/Issues in getID3() that may be fixed eventually
376: ===========================================================================
377: http://www.getid3.org/phpBB3/viewtopic.php?t=25
378:
379: * Cannot determine bitrate for MPEG video with VBR video data
380: (need documentation)
381: * Interlace/progressive cannot be determined for MPEG video
382: (need documentation)
383: * MIDI playtime is sometimes inaccurate
384: * AAC-RAW mode files cannot be identified
385: * WavPack-RAW mode files cannot be identified
386: * mp4 files report lots of "Unknown QuickTime atom type"
387: (need documentation)
388: * Encrypted ASF/WMA/WMV files warn about "unhandled GUID
389: ASF_Content_Encryption_Object"
390: * Bitrate split between audio and video cannot be calculated for
391: NSV, only the total bitrate. (need documentation)
392: * All Ogg formats (Vorbis, OggFLAC, Speex) are affected by the
393: problem of large VorbisComments spanning multiple Ogg pages, but
394: but only OggVorbis files can be processed with vorbiscomment.
395: * The version of "head" supplied with Mac OS 10.2.8 (maybe other
396: versions too) does only understands a single option (-n) and
397: therefore fails. getID3 ignores this and returns wrong md5_data.

401: Known Bugs/Issues in getID3() that cannot be fixed
402: --------------------------------------------------
403: http://www.getid3.org/phpBB3/viewtopic.php?t=25
404:
405: * 32-bit PHP installations only:
406: Files larger than 2GB cannot always be parsed fully by getID3()
407: due to limitations in the 32-bit PHP filesystem functions.
408: NOTE: Since v1.7.8b3 there is partial support for larger-than-
409: 2GB files, most of which will parse OK, as long as no critical
410: data is located beyond the 2GB offset.
411: Known will-work:
412: * all file formats on 64-bit PHP
413: * ZIP (format doesn't support files >2GB)
414: * FLAC (current encoders don't support files >2GB)
415: Known will-not-work:
416: * ID3v1 tags (always located at end-of-file)
417: * Lyrics3 tags (always located at end-of-file)
418: * APE tags (always located at end-of-file)
419: Maybe-will-work:
420: * Quicktime (will work if needed metadata is before 2GB offset,
421: that is if the file has been hinted/optimized for streaming)
422: * RIFF.WAV (should work fine, but gives warnings about not being
423: able to parse all chunks)
424: * RIFF.AVI (playtime will probably be wrong, is only based on
425: "movi" chunk that fits in the first 2GB, should issue error
426: to show that playtime is incorrect. Other data should be mostly
427: correct, assuming that data is constant throughout the file)
428: * PHP <= v5 on Windows cannot read UTF-8 filenames
429:
430:
431: Known Bugs/Issues in other programs
432: -----------------------------------
433: http://www.getid3.org/phpBB3/viewtopic.php?t=25
434:
435: * Windows Media Player (up to v11) and iTunes (up to v10+) do
436: not correctly handle ID3v2.3 tags with UTF-16BE+BOM
437: encoding (they assume the data is UTF-16LE+BOM and either
438: crash (WMP) or output Asian character set (iTunes)
439: * Winamp (up to v2.80 at least) does not support ID3v2.4 tags,
440: only ID3v2.3
441: see: http://forums.winamp.com/showthread.php?postid=387524
442: * Some versions of Helium2 (www.helium2.com) do not write
443: ID3v2.4-compliant Frame Sizes, even though the tag is marked
444: as ID3v2.4) (detected by getID3())
445: * MP3ext V3.3.17 places a non-compliant padding string at the end
446: of the ID3v2 header. This is supposedly fixed in v3.4b21 but
447: only if you manually add a registry key. This fix is not yet
448: confirmed. (detected by getID3())
449: * CDex v1.40 (fixed by v1.50b7) writes non-compliant Ogg comment
450: strings, supposed to be in the format "NAME=value" but actually
451: written just "value" (detected by getID3())
452: * Oggenc 0.9-rc3 flags the encoded file as ABR whether it's
453: actually ABR or VBR.
454: * iTunes (versions "X v2.0.3", "v3.0.1" are known-guilty, probably
455: other versions are too) writes ID3v2.3 comment tags using a
456: frame name 'COM ' which is not valid for ID3v2.3+ (it's an
457: ID3v2.2-style frame name) (detected by getID3())
458: * MP2enc does not encode mono CBR MP2 files properly (half speed
459: sound and double playtime)
460: * MP2enc does not encode mono VBR MP2 files properly (actually
461: encoded as stereo)
462: * tooLAME does not encode mono VBR MP2 files properly (actually
463: encoded as stereo)
464: * AACenc encodes files in VBR mode (actually ABR) even if CBR is
465: specified
466: * AAC/ADIF - bitrate_mode = cbr for vbr files
467: * LAME 3.90-3.92 prepends one frame of null data (space for the
468: LAME/VBR header, but it never gets written) when encoding in CBR
469: mode with the DLL
470: * Ahead Nero encodes TwinVQF with a DSIZ value (which is supposed
471: to be the filesize in bytes) of "0" for TwinVQF v1.0 and "1" for
472: TwinVQF v2.0 (detected by getID3())
473: * Ahead Nero encodes TwinVQF files 1 second shorter than they
474: should be
475: * AAC-ADTS files are always actually encoded VBR, even if CBR mode
476: is specified (the CBR-mode switches on the encoder enable ABR
477: mode, not CBR as such, but it's not possible to tell the
478: difference between such ABR files and true VBR)
479: * STREAMINFO.audio_signature in OggFLAC is always null. "The reason
480: it's like that is because there is no seeking support in
481: libOggFLAC yet, so it has no way to go back and write the
482: computed sum after encoding. Seeking support in Ogg FLAC is the
483: #1 item for the next release." - Josh Coalson (FLAC developer)
484: NOTE: getID3() will calculate md5_data in a method similar to
485: other file formats, but that value cannot be compared to the
486: md5_data value from FLAC data in a FLAC file format.
487: * STREAMINFO.audio_signature is not calculated in FLAC v0.3.0 &
488: v0.4.0 - getID3() will calculate md5_data in a method similar to
489: other file formats, but that value cannot be compared to the
490: md5_data value from FLAC v0.5.0+
491: * RioPort (various versions including 2.0 and 3.11) tags ID3v2 with
492: a WCOM frame that has no data portion
493: * Earlier versions of Coolplayer adds illegal ID3 tags to Ogg Vorbis
494: files, thus making them corrupt.
495: * Meracl ID3 Tag Writer v1.3.4 (and older) incorrectly truncates the
496: last byte of data from an MP3 file when appending a new ID3v1 tag.
497: (detected by getID3())
498: * Lossless-Audio files encoded with and without the -noseek switch
499: do actually differ internally and therefore cannot match md5_data
500: * iTunes has been known to append a new ID3v1 tag on the end of an
501: existing ID3v1 tag when ID3v2 tag is also present
502: (detected by getID3())
503: * MediaMonkey may write a blank RGAD ID3v2 frame but put actual
504: replay gain adjustments in a series of user-defined TXXX frames
505: (detected and handled by getID3() since v1.9.2)
