Example #1 id3_remove_tag() example
<?php
$result = id3_remove_tag( "path/to/example.mp3", ID3_V1_0 );
if ($result === true) {
echo "Tag succesfully removed\n";
}
?>
If the file is writable and contained a 1.0 tag, this will output:
Tag succesfully removed
Note: Currently id3_remove_tag() only supports version 1.0 and 1.1. If you choose to remove a 1.0 tag and the file contains a 1.1 tag, this tag will be removed, as v1.1 is only an extension of 1.0.
