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:
|
||
|
|
||
|
// 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 :)

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:
|
||
|
function getID3($filename) { return unpack('a3TAG/a30title/a30artist/a30album/a4year/a28comment/c1track/c1genreid', substr(file_get_contents($filename), -128)); }

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

Known Bugs/Issues in getID3() that cannot be fixed
|

|
--------------------------------------------------
|
||
|
http://www.getid3.org/phpBB3/viewtopic.php?t=25
|
||
|
|
||
|
* 32-bit PHP installations only:
|
||
|
Files larger than 2GB cannot always be parsed fully by getID3()
|
||
|
due to limitations in the 32-bit PHP filesystem functions.
|
||
|
NOTE: Since v1.7.8b3 there is partial support for larger-than-
|
||
|
2GB files, most of which will parse OK, as long as no critical
|
||
|
data is located beyond the 2GB offset.
|
||
|
Known will-work:
|
||
|
* all file formats on 64-bit PHP
|
||
|
* ZIP (format doesn't support files >2GB)
|
||
|
* FLAC (current encoders don't support files >2GB)

Known will-not-work:
|
||
|
* ID3v1 tags (always located at end-of-file)
|
||
|
* Lyrics3 tags (always located at end-of-file)
|
||
|
* APE tags (always located at end-of-file)
|
||
|
Maybe-will-work:
|
||
|
* Quicktime (will work if needed metadata is before 2GB offset,
|
||
|
that is if the file has been hinted/optimized for streaming)
|
||
|
* RIFF.WAV (should work fine, but gives warnings about not being
|
||
|
able to parse all chunks)
|
||
|
* RIFF.AVI (playtime will probably be wrong, is only based on
|
||
|
"movi" chunk that fits in the first 2GB, should issue error
|
||
|
to show that playtime is incorrect. Other data should be mostly
|
||
|
correct, assuming that data is constant throughout the file)
|
||
|
* PHP <= v5 on Windows cannot read UTF-8 filenames

-----------------------------------
|
||
|
http://www.getid3.org/phpBB3/viewtopic.php?t=25
|
||
|
|
||
|
* Windows Media Player (up to v11) and iTunes (up to v10+) do
|
||
|
not correctly handle ID3v2.3 tags with UTF-16BE+BOM
|
||
|
encoding (they assume the data is UTF-16LE+BOM and either
|
||
|
crash (WMP) or output Asian character set (iTunes)
|
||
|
* Winamp (up to v2.80 at least) does not support ID3v2.4 tags,
|
||
|
only ID3v2.3
|
||
|
see: http://forums.winamp.com/showthread.php?postid=387524
|
||
|
* Some versions of Helium2 (www.helium2.com) do not write
|
||
|
ID3v2.4-compliant Frame Sizes, even though the tag is marked
|
||
|
as ID3v2.4) (detected by getID3())
|
||
|
* MP3ext V3.3.17 places a non-compliant padding string at the end
|
||
|
of the ID3v2 header. This is supposedly fixed in v3.4b21 but
|
||
|
only if you manually add a registry key. This fix is not yet
|
||
|
confirmed. (detected by getID3())
|
||
|
* CDex v1.40 (fixed by v1.50b7) writes non-compliant Ogg comment
|
||
|
strings, supposed to be in the format "NAME=value" but actually
|
||
|
written just "value" (detected by getID3())
|
||
|
* Oggenc 0.9-rc3 flags the encoded file as ABR whether it's
|
||
|
actually ABR or VBR.
|
||
|
* iTunes (versions "X v2.0.3", "v3.0.1" are known-guilty, probably
|
||
|
other versions are too) writes ID3v2.3 comment tags using a
|
||
|
frame name 'COM ' which is not valid for ID3v2.3+ (it's an
|
||
|
ID3v2.2-style frame name) (detected by getID3())
|
||
|
* MP2enc does not encode mono CBR MP2 files properly (half speed
|
||
|
sound and double playtime)
|
||
|
* MP2enc does not encode mono VBR MP2 files properly (actually
|
||
|
encoded as stereo)
|
||
|
* tooLAME does not encode mono VBR MP2 files properly (actually
|
||
|
encoded as stereo)
|
||
|
* AACenc encodes files in VBR mode (actually ABR) even if CBR is
|
||
|
specified
|
||
|
* AAC/ADIF - bitrate_mode = cbr for vbr files
|
||
|
* LAME 3.90-3.92 prepends one frame of null data (space for the
|
||
|
LAME/VBR header, but it never gets written) when encoding in CBR
|
||
|
mode with the DLL
|
||
|
* Ahead Nero encodes TwinVQF with a DSIZ value (which is supposed
|
||
|
to be the filesize in bytes) of "0" for TwinVQF v1.0 and "1" for
|
||
|
TwinVQF v2.0 (detected by getID3())
|
||
|
* Ahead Nero encodes TwinVQF files 1 second shorter than they
|
||
|
should be
|
||
|
* AAC-ADTS files are always actually encoded VBR, even if CBR mode
|
||
|
is specified (the CBR-mode switches on the encoder enable ABR
|
||
|
mode, not CBR as such, but it's not possible to tell the
|
||
|
difference between such ABR files and true VBR)
|
||
|
* STREAMINFO.audio_signature in OggFLAC is always null. "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. Seeking support in Ogg FLAC is the
|
||
|
#1 item for the next release." - Josh Coalson (FLAC developer)
|
||
|
NOTE: getID3() will calculate md5_data in a method similar to
|
||
|
other file formats, but that value cannot be compared to the
|
||
|
md5_data value from FLAC data in a FLAC file format.
|
||
|
* STREAMINFO.audio_signature is not calculated in FLAC v0.3.0 &
|
||
|
v0.4.0 - getID3() will calculate md5_data in a method similar to
|
||
|
other file formats, but that value cannot be compared to the
|
||
|
md5_data value from FLAC v0.5.0+
|
||
|
* RioPort (various versions including 2.0 and 3.11) tags ID3v2 with
|
||
|
a WCOM frame that has no data portion
|
||
|
* Earlier versions of Coolplayer adds illegal ID3 tags to Ogg Vorbis
|
||
|
files, thus making them corrupt.
|
||
|
* Meracl ID3 Tag Writer v1.3.4 (and older) incorrectly truncates the
|
||
|
last byte of data from an MP3 file when appending a new ID3v1 tag.
|
||
|
(detected by getID3())
|
||
|
* Lossless-Audio files encoded with and without the -noseek switch
|
||
|
do actually differ internally and therefore cannot match md5_data
|
||
|
* iTunes has been known to append a new ID3v1 tag on the end of an
|
||
|
existing ID3v1 tag when ID3v2 tag is also present
|
||
|
(detected by getID3())
|
||
|
* MediaMonkey may write a blank RGAD ID3v2 frame but put actual
|
||
|
replay gain adjustments in a series of user-defined TXXX frames
|
||
|
(detected and handled by getID3() since v1.9.2)
