使用symfony2控制器的外部库

Question

I would like to use php library in symfony2 Command. http://phpmidiparser.com/quickstart

I put the library on the same folder of symfony2 but in vain.

Command/Midi/bootstrap.php
Command/myCommand.php

$ php app/console top:myCommand

syntax error, unexpected 'use' (T_USE) in error at use \Midi\Parsing\FileParser;

require_once 'Midi/bootstrap.php';

use \Midi\Parsing\FileParser;
use \Midi\Reporting\TextFormatter;
use \Midi\Reporting\Printer;

$parser = new FileParser();
$parser->load('/path/to/midi/file.mid');

$printer = new Printer(new TextFormatter(), $parser);
$printer->printAll();

I use this library only in Command ,so I don't need to register this on autoload.

Please teach me basic guideline of using external library, where should I put the library and how can I 'require'?

Answer 1

usekeyword must appear before require_once (http://php.net/manual/en/language.namespaces.importing.php)

use \Midi\Parsing\FileParser;
use \Midi\Reporting\TextFormatter;
use \Midi\Reporting\Printer;

require_once 'Midi/bootstrap.php';

$parser = new FileParser();
$parser->load('/path/to/midi/file.mid');

$printer = new Printer(new TextFormatter(), $parser);
$printer->printAll();
