id3_get_version

(PECL id3 >= 0.1)

id3_get_versionGet version of an ID3 tag

说明

int id3_get_version ( string $filename )

id3_get_version() 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.

参数

filename

The path to the MP3 file

Instead of a filename you may also pass a valid stream resource

返回值

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 .

范例

Example #1 id3_get_version() example

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

以上例程的输出类似于:

Contains a 1.x tag
Contains a 1.1 tag
