 154  
 155  
 156  
 157  Usage
 158  ===========================================================================
 159  
 160  See /demos/demo.basic.php for a very basic use of getID3() with no
 161  fancy output, just scanning one file.
 162  
 163  See structure.txt for the returned data structure.
 164  
 165  *>  For an example of a complete directory-browsing,       <*
 166  *>  file-scanning implementation of getID3(), please run   <*
 167  *>  /demos/demo.browse.php                                 <*
 168  
 169  See /demos/demo.mysql.php for a sample recursive scanning code that
 170  scans every file in a given directory, and all sub-directories, stores
 171  the results in a database and allows various analysis / maintenance
 172  operations
 173  
 174  To analyze remote files over HTTP or FTP you need to copy the file
 175  locally first before running getID3(). Your code would look something
 176  like this:
 177  
 178  // Copy remote file locally to scan with getID3()
 179  $remotefilename = 'http://www.example.com/filename.mp3';
 180  if ($fp_remote = fopen($remotefilename, 'rb')) {
 181      $localtempfilename = tempnam('/tmp', 'getID3');
 182      if ($fp_local = fopen($localtempfilename, 'wb')) {
 183          while ($buffer = fread($fp_remote, 32768)) {
 184              fwrite($fp_local, $buffer);
 185          }
 186          fclose($fp_local);
 187  
 188          $remote_headers = array_change_key_case(get_headers($remotefilename, 1), CASE_LOWER);
 189          $remote_filesize = (isset($remote_headers['content-length']) ? (is_array($remote_headers['content-length']) ? $remote_headers['content-length'][count($remote_headers['content-length']) - 1] : $remote_headers['content-length']) : null);
 190  
 191          // Initialize getID3 engine
 192          $getID3 = new getID3;
 193  
 194          $ThisFileInfo = $getID3->analyze($localtempfilename, $remote_filesize, basename($remotefilename));
 195  
 196          // Delete temporary file
 197          unlink($localtempfilename);
 198      }
 199      fclose($fp_remote);
 200  }
 201  
 202  Note: since v1.9.9-20150212 it is possible a second and third parameter
 203  to $getID3->analyze(), for original filesize and original filename
 204  respectively. This permits you to download only a portion of a large remote
 205  file but get accurate playtime estimates, assuming the format only requires
 206  the beginning of the file for correct format analysis.
 207  
 208  See /demos/demo.write.php for how to write tags.
 209  
 210  
 211  
 212  What does the returned data structure look like?
 213  ===========================================================================
 214  
 215  See structure.txt
 216  
 217  It is recommended that you look at the output of
 218  /demos/demo.browse.php scanning the file(s) you're interested in to
 219  confirm what data is actually returned for any particular filetype in
 220  general, and your files in particular, as the actual data returned
 221  may vary considerably depending on what information is available in
 222  the file itself.
 223  
 224  
 225  
 226  Notes
 227  ===========================================================================
 228  
 229  getID3() 1.x:
 230  If the format parser encounters a critical problem, it will return
 231  something in $fileinfo['error'], describing the encountered error. If
 232  a less critical error or notice is generated it will appear in
 233  $fileinfo['warning']. Both keys may contain more than one warning or
 234  error. If something is returned in ['error'] then the file was not
 235  correctly parsed and returned data may or may not be correct and/or
 236  complete. If something is returned in ['warning'] (and not ['error'])
 237  then the data that is returned is OK - usually getID3() is reporting
 238  errors in the file that have been worked around due to known bugs in
 239  other programs. Some warnings may indicate that the data that is
 240  returned is OK but that some data could not be extracted due to
 241  errors in the file.
 242  
 243  getID3() 2.x:
 244  See above except errors are thrown (so you will only get one error).
 245  
 246  
 247  
 248  Disclaimer
 249  ===========================================================================
 250  
 251  getID3() has been tested on many systems, on many types of files,
 252  under many operating systems, and is generally believe to be stable
 253  and safe. That being said, there is still the chance there is an
 254  undiscovered and/or unfixed bug that may potentially corrupt your
 255  file, especially within the writing functions. By using getID3() you
 256  agree that it's not my fault if any of your files are corrupted.
 257  In fact, I'm not liable for anything :)

 282  FAQ:
 283  Q: Can I use getID3() in my program? Do I need a commercial license?
 284  A: You're generally free to use getID3 however you see fit. The only
 285     case in which you would require a commercial license is if you're
 286     selling your closed-source program that integrates getID3. If you
 287     sell your program including a copy of getID3, that's fine as long
 288     as you include a copy of the sourcecode when you sell it.  Or you
 289     can distribute your code without getID3 and say "download it from
 290     getid3.sourceforge.net"
 291  
 292  
 293  
 294  Why is it called "getID3()" if it does so much more than just that?
 295  ===========================================================================
 296  
 297  v0.1 did in fact just do that. I don't have a copy of code that old, but I
 298  could essentially write it today with a one-line function:
 299    function getID3($filename) { return unpack('a3TAG/a30title/a30artist/a30album/a4year/a28comment/c1track/c1genreid', substr(file_get_contents($filename), -128)); }
 300

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

 409  
 410  Known Bugs/Issues in getID3() that cannot be fixed
 411  --------------------------------------------------
 412  https://www.getid3.org/phpBB3/viewtopic.php?t=25
 413  
 414  * 32-bit PHP installations only:
 415    Files larger than 2GB cannot always be parsed fully by getID3()
 416    due to limitations in the 32-bit PHP filesystem functions.
 417    NOTE: Since v1.7.8b3 there is partial support for larger-than-
 418    2GB files, most of which will parse OK, as long as no critical
 419    data is located beyond the 2GB offset.
 420    Known will-work:
 421    * all file formats on 64-bit PHP
 422    * ZIP  (format doesn't support files >2GB)
 423    * FLAC (current encoders don't support files >2GB)
 424    Known will-not-work:
 425    * ID3v1 tags (always located at end-of-file)
 426    * Lyrics3 tags (always located at end-of-file)
 427    * APE tags (always located at end-of-file)
 428    Maybe-will-work:
 429    * Quicktime (will work if needed metadata is before 2GB offset,
 430      that is if the file has been hinted/optimized for streaming)
 431    * RIFF.WAV (should work fine, but gives warnings about not being
 432      able to parse all chunks)
 433    * RIFF.AVI (playtime will probably be wrong, is only based on
 434      "movi" chunk that fits in the first 2GB, should issue error
 435      to show that playtime is incorrect. Other data should be mostly
 436      correct, assuming that data is constant throughout the file)
 437  * PHP <= v5 on Windows cannot read UTF-8 filenames
 438  
 439  
 440  Known Bugs/Issues in other programs
 441  -----------------------------------
 442  https://www.getid3.org/phpBB3/viewtopic.php?t=25
 443  
 444  * MusicBrainz Picard (at least up to v1.3.2) writes multiple
 445    ID3v2.3 genres in non-standard forward-slash separated text
 446    rather than parenthesis-numeric+refinement style per the ID3v2.3
 447    specs. Tags written in ID3v2.4 mode are written correctly.
 448    (detected and worked around by getID3())
 449  * PZ TagEditor v4.53.408 has been known to insert ID3v2.3 frames
 450    into an existing ID3v2.2 tag which, of course, breaks things
 451  * Windows Media Player (up to v11) and iTunes (up to v10+) do
 452      not correctly handle ID3v2.3 tags with UTF-16BE+BOM
 453      encoding (they assume the data is UTF-16LE+BOM and either
 454      crash (WMP) or output Asian character set (iTunes)
 455  * Winamp (up to v2.80 at least) does not support ID3v2.4 tags,
 456      only ID3v2.3
 457      see: http://forums.winamp.com/showthread.php?postid=387524
 458  * Some versions of Helium2 (www.helium2.com) do not write
 459      ID3v2.4-compliant Frame Sizes, even though the tag is marked
 460      as ID3v2.4)  (detected by getID3())
 461  * MP3ext V3.3.17 places a non-compliant padding string at the end
 462      of the ID3v2 header. This is supposedly fixed in v3.4b21 but
 463      only if you manually add a registry key. This fix is not yet
 464      confirmed.  (detected by getID3())
 465  * CDex v1.40 (fixed by v1.50b7) writes non-compliant Ogg comment
 466      strings, supposed to be in the format "NAME=value" but actually
 467      written just "value"  (detected by getID3())
 468  * Oggenc 0.9-rc3 flags the encoded file as ABR whether it's
 469      actually ABR or VBR.
 470  * iTunes (versions "v7.0.0.70" is known-guilty, probably
 471      other versions are too) writes ID3v2.3 comment tags using an
 472      ID3v2.2 frame name (3-bytes) null-padded to 4 bytes which is
 473      not valid for ID3v2.3+
 474      (detected by getID3() since 1.9.12-201603221746)
 475  * iTunes (versions "X v2.0.3", "v3.0.1" are known-guilty, probably
 476      other versions are too) writes ID3v2.3 comment tags using a
 477      frame name 'COM ' which is not valid for ID3v2.3+ (it's an
 478      ID3v2.2-style frame name)  (detected by getID3())
 479  * MP2enc does not encode mono CBR MP2 files properly (half speed
 480      sound and double playtime)
 481  * MP2enc does not encode mono VBR MP2 files properly (actually
 482      encoded as stereo)
 483  * tooLAME does not encode mono VBR MP2 files properly (actually
 484      encoded as stereo)
 485  * AACenc encodes files in VBR mode (actually ABR) even if CBR is
 486     specified
 487  * AAC/ADIF - bitrate_mode = cbr for vbr files
 488  * LAME 3.90-3.92 prepends one frame of null data (space for the
 489    LAME/VBR header, but it never gets written) when encoding in CBR
 490    mode with the DLL
 491  * Ahead Nero encodes TwinVQF with a DSIZ value (which is supposed
 492    to be the filesize in bytes) of "0" for TwinVQF v1.0 and "1" for
 493    TwinVQF v2.0  (detected by getID3())
 494  * Ahead Nero encodes TwinVQF files 1 second shorter than they
 495    should be
 496  * AAC-ADTS files are always actually encoded VBR, even if CBR mode
 497    is specified (the CBR-mode switches on the encoder enable ABR
 498    mode, not CBR as such, but it's not possible to tell the
 499    difference between such ABR files and true VBR)
 500  * STREAMINFO.audio_signature in OggFLAC is always null. "The reason
 501    it's like that is because there is no seeking support in
 502    libOggFLAC yet, so it has no way to go back and write the
 503    computed sum after encoding. Seeking support in Ogg FLAC is the
 504    #1 item for the next release." - Josh Coalson (FLAC developer)
 505    NOTE: getID3() will calculate md5_data in a method similar to
 506    other file formats, but that value cannot be compared to the
 507    md5_data value from FLAC data in a FLAC file format.
 508  * STREAMINFO.audio_signature is not calculated in FLAC v0.3.0 &
 509    v0.4.0 - getID3() will calculate md5_data in a method similar to
 510    other file formats, but that value cannot be compared to the
 511    md5_data value from FLAC v0.5.0+
 512  * RioPort (various versions including 2.0 and 3.11) tags ID3v2 with
 513    a WCOM frame that has no data portion
 514  * Earlier versions of Coolplayer adds illegal ID3 tags to Ogg Vorbis
 515    files, thus making them corrupt.
 516  * Meracl ID3 Tag Writer v1.3.4 (and older) incorrectly truncates the
 517    last byte of data from an MP3 file when appending a new ID3v1 tag.
 518    (detected by getID3())
 519  * Lossless-Audio files encoded with and without the -noseek switch
 520    do actually differ internally and therefore cannot match md5_data
 521  * iTunes has been known to append a new ID3v1 tag on the end of an
 522    existing ID3v1 tag when ID3v2 tag is also present
 523    (detected by getID3())
 524  * MediaMonkey may write a blank RGAD ID3v2 frame but put actual
 525    replay gain adjustments in a series of user-defined TXXX frames
 526    (detected and handled by getID3() since v1.9.2)
