id3_set_tag — Update information stored in an ID3 tag
id3_set_tag() is used to change the information stored of an ID3 tag. If no tag has been present, it will be added to the file.
The path to the MP3 file
Instead of a filename you may also pass a valid stream resource
An associative array of tag keys and values
The following keys may be used in the associative array:
| key | possible value | available in version |
|---|---|---|
| title | string with maximum of 30 characters | v1.0, v1.1 |
| artist | string with maximum of 30 characters | v1.0, v1.1 |
| album | string with maximum of 30 characters | v1.0, v1.1 |
| year | 4 digits | v1.0, v1.1 |
| genre | integer value between 0 and 147 | v1.0, v1.1 |
| comment | string with maximum of 30 characters (28 in v1.1) | v1.0, v1.1 |
| track | integer between 0 and 255 | v1.1 |
Allows you to specify the version of the tag as MP3 files may contain both, version 1.x and version 2.x tags
如果成功则返回 TRUE，失败则返回 FALSE。
Example#1 id3_set_tag() example
<?php
$data = array(
"title" => "Re:Start",
"artist" => "Re:\Legion",
"comment" => "A nice track"
);
$result = id3_set_tag( "path/to/example.mp3", $data, ID3_V1_0 );
if ($result === true) {
echo "Tag succesfully updated\n";
}
?>
If the file is writable, this will output:
Tag succesfully updated
Note: Currently id3_remove_tag() only supports version 1.0 and 1.1.
