Answer 1

Edit:
As #ajtrichards says:
"You don't have permission to read the files in /var/www/music. You'll need to allow access to your web server"
Go to your /var/www/music folder and give the right permissions for your server to READ in there.
If you use Apache:

PHP has two environments.
The web environment.
The CLI environment.
Your extension works perfectly on the CLI environment because you added the PECL extension on the CLI php.ini.
You need to make sure the extension is added to the web php.ini.
To test it, make a test.php with a phpinfo call.
And access it via browser.
This will output all the php.ini configuration for the "web" PHP.
Then search for your ID3 extension in all the list of extensions.
If it does not display, then is not added to the "web environment" php.ini.
To add it, you must do the same that you did to add it to the CLI php.ini
Something like, adding this line
extension=id3.so
PS:
Dude, where's my php.ini?

Answer 2

This works via the command line PHP as the user root has permission to read from the folder /var/www/music, as Maniteja uses sudo php to run the php file.
However, when the script is running via PHP in the web browser the web server does not have the permission to read from the folder, hence the error:
PHP Warning: id3_get_tag(/var/www/music/rem.mp3): failed to open
stream: Permission denied in /var/www/index.php on line 2
To resolve the problem - grant read access to your web server user.
