+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 5.3.0 (or higher) for getID3() 1.9.17 (and up)
+* PHP 5.3.0 (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($fp_remote, 32768)) {
+ fwrite($fp_local, $buffer);
+ }
+ fclose($fp_local);
+
+ $remote_headers = array_change_key_case(get_headers($remotefilename, 1), CASE_LOWER);
+ $remote_filesize = (isset($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);
+
+ // Initialize getID3 engine
+ $getID3 = new getID3;
+
+ $ThisFileInfo = $getID3->analyze($localtempfilename, $remote_filesize, basename($remotefilename));
+
+ // Delete temporary file
+ unlink($localtempfilename);
+ }
+ fclose($fp_remote);
+}
+
+Note: since v1.9.9-20150212 it is possible a second and third parameter
+to $getID3->analyze(), for original filesize and original filename
+respectively. This permits you to download only a portion of a large remote
+file but get accurate playtime estimates, assuming the format only requires
+the beginning of the file for correct format analysis.
+
+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
+===========================================================================
+https://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
+--------------------------------------------------
+https://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
+
+
+Known Bugs/Issues in other programs
+-----------------------------------
+https://www.getid3.org/phpBB3/viewtopic.php?t=25
+
+* MusicBrainz Picard (at least up to v1.3.2) writes multiple
+ ID3v2.3 genres in non-standard forward-slash separated text
+ rather than parenthesis-numeric+refinement style per the ID3v2.3
+ specs. Tags written in ID3v2.4 mode are written correctly.
+ (detected and worked around by getID3())
+* PZ TagEditor v4.53.408 has been known to insert ID3v2.3 frames
+ into an existing ID3v2.2 tag which, of course, breaks things
+* 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 "v7.0.0.70" is known-guilty, probably
+ other versions are too) writes ID3v2.3 comment tags using an
+ ID3v2.2 frame name (3-bytes) null-padded to 4 bytes which is
+ not valid for ID3v2.3+
+ (detected by getID3() since 1.9.12-201603221746)
+* 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)
+
