Shift automatically applies the Laravel coding style - which uses the PSR-2 coding style as a base with some minor additions. You may customize the adopted coding style by adding your own [PHP CS Fixer][1] `.php_cs` config file to your project root. Feel free to use [Shift's Laravel ruleset][2] to help you get started.

|
|
// | Example wrapper class to extract information from audio files |
|
|
// | through getID3(). |
|
|
// | |
|
|
// | getID3() returns a lot of information. Much of this information is |
|
|
// | not needed for the end-application. It is also possible that some |
|
|
// | users want to extract specific info. Modifying getID3() files is a |
|
|
// | bad idea, as modifications needs to be done to future versions of |
|
|
// | getID3(). |
|
|
// | |
|
|
// | Modify this wrapper class instead. This example extracts certain |
|
|
// | fields only and adds a new root value - encoder_options if possible. |
|
|
// | It also checks for mp3 files with wave headers. |
|
|
// +----------------------------------------------------------------------+
|
|
// | Example code: |
|
|
// | $au = new AudioInfo(); |
|
|
// | print_r($au->Info('file.flac'); |
