id3_get_version - Get version of an ID3 tag

SYNOPSIS

       int id3_get_version (string  $filename)

DESCRIPTION

       id3_get_version(3) retrieves the version(s) of the ID3 tag(s) in the MP3 file.

	If a file contains an ID3 v1.1 tag, it always contains a 1.0 tag, as version 1.1 is just an extension of 1.0.

PARAMETERS

	      o $filename
		- The path to the MP3 file  Instead of a filename you may also pass a valid stream resource

RETURN VALUES

	Returns  the  version  number  of  the ID3 tag of the file. As a tag can contain ID3 v1.x and v2.x tags, the return value of this function
       should be bitwise compared with the predefined constants ID3_V1_0, ID3_V1_1 and ID3_V2.

EXAMPLES

       Example #1

	      id3_get_version(3) example

	      <?php
	      $version = id3_get_version( "path/to/example.mp3" );
	      if ($version & ID3_V1_0) {
		  echo "Contains a 1.x tag
";
	      }
	      if ($version & ID3_V1_1) {
		  echo "Contains a 1.1 tag
";
	      }
	      if ($version & ID3_V2) {
		  echo "Contains a 2.x tag
";
	      }
	      ?>

	      The above example will output something similar to:

	      Contains a 1.x tag
	      Contains a 1.1 tag
