What
does the returned data structure look
like?
================================================
Hint: If you take a
look at the nicely-formatted output of
/demos/demo.browse.php you can
generally see where the data you want
is returned.
Note that what is
described below is only a rough guide to what data
is actually returned by
getID3(), since the actual data returned
depends entirely on what data is
in your file, what type of file it
is, what kind of data is in the tags,
etc. In addition, some formats
(Quicktime for example) use a freeform
recursive structure that is
impossible to document completely.
In the vast
majority of cases, all the data you'll need is located
in the root of the
array or the special arrays described below in
Section 1 (['audio'],
['video'], ['tags_html'], ['replay_gain']).
It is suggested that for most
applications you should use tag data
from the root ['tags_html'] array, as
this is the only location
where data is stored in a consistant format:
HTML-compatible
character entities (ie Ӓ) for characters outside
the 0x20-0x7F
range (printable ISO-8859-1 characters). This data can be
used as-is
for output in HTML, and can be converted to whatever character
set
you wish to use if the output is not HTML.
If you want to merge all
available tags (for example, ID3v2 + ID3v1)
into one array, you can
call
getid3_lib::CopyTagsToComments($ThisFileInfo)
and you'll then have
['comments'] and ['comments_html'] which are
identical to ['tags'] and
['tags_html'] except the array is one
dimension shorter (no tag type array
keys). For example, artist is:
['tags_html']['id3v1']['artist'][0] or
['comments_html']['artist'][0]
Some commonly-used information is found in
these locations:
File type: ['fileformat'] // ex
'mp3'
Song length: ['playtime_string'] // ex '3:45'
(minutes:seconds)
['playtime_seconds'] // ex
225.13 (seconds)
Overall bitrate: ['bitrate'] // ex
113485.71 (bits-per-second - divide by 1000 for kbps)
Audio frequency:
['audio']['sample_rate'] // ex 44100 (Hertz)
Artist name:
['comments_html']['artist'][0] // ex 'Elvis' (if CopyTagsToComments() is
used - see above)
//
more than one artist may be present, you may want to use implode:
// implode(' & ',
['comments_html']['artist'])
