Example #1 Reading an OGG/Vorbis file
<?php
dl ( "oggvorbis.so" );
$fp = fopen ( 'ogg://myaudio.ogg' , 'r' );
$metadata = stream_get_meta_data ( $fp );
$songdata = $metadata [ 'wrapper_data' ][ 0 ];
echo "OGG/Vorbis file encoded by: { $songdata [ 'vendor' ]} \n." ;
echo " { $songdata [ 'channels' ]} channels of { $songdata [ 'rate' ]} Hz sampling encoded at { $songdata [ 'bitrate_nominal' ]} bps.\n" ;
foreach( $songdata [ 'comments' ] as $comment ) {
echo " $comment \n" ;
}
while ( $audio_data = fread ( $fp , 8192 )) {
}
fclose ( $fp );
?>
Example #2 Encode an audio file to OGG/Vorbis
<?php
dl ( 'oggvorbis.so' );
$context = stream_context_create (array( 'ogg' =>array(
'pcm_mode' => OGGVORBIS_PCM_S8 ,
'rate' => 44100 ,
'bitrate' => 0.5 ,
'channels' => 1 ,
'serialno' => 12345 )));
$ogg = fopen ( 'ogg://mysong.ogg' , 'a' , false , $context );
$pcm = fopen ( 'mysample.pcm' , 'r' );
stream_copy_to_stream ( $pcm , $ogg );
fclose ( $pcm );
fclose ( $ogg );
?>
