Symfony2 PHP Parse error when invoking app/console cache:clear

Question

Whenever I am trying to clear the cache on Symfony2 I am constantly getting the following error:

PHP Parse error:  parse error in /Users/Adam/Sites/MyApp/src/MyApp/MainBundle/Services/TransactionManager.php on line 177
PHP Stack trace:
PHP   1. {main}() /Users/Adam/Sites/MyApp/app/console:0

PHP  11. Composer\Autoload\ClassLoader->loadClass() /Users/Adam/Sites/MyApp/vendor/jms/aop-bundle/JMS/AopBundle/DependencyInjection/Compiler/PointcutMatchingPass.php:0

Here's what line 177 looks like:

/**
 * {@inheritDoc} 
 */
public function findAwaitingPaymentTransactionsByUserId( $dateRange = [] )
 {
   // ...
 }

Any idea why this is? This just happened after I upgrade my Lion OS X, before it works just fine with the code above.

What version of PHP are you running? Greater than or equal to 5.3? — user1105787

@DavidEugenePeterson I am running PHP 5.3.26 (cli) (built: Jul 7 2013 19:05:08) — adit

Set $dateRange = [] to $dateRange = NULL then clear cache manually in the app/cache directory. Can you execute the app/console router:debug command afterwards without error? — user1105787

@DavidEugenePeterson actually I am running PHP Version 5.4.13. And yes after changing to $dateRange = NULL the error goes to the next line that has the [] issue. I can't use [] in 5.4? — adit

I'm confused there's only one line in the code you provide that uses the short array syntax []. Which line, exactly, is line 177? You have 7 lines of code there. — Sherif

The method's default argument $dateRange = [] uses the short array syntax that was introduced in PHP 5.4.

Your PHP command line interface uses PHP 5.3 that can't understand this syntax.

Therefore the method declaration results in a PHP Parse error.

Change the method to ...

// array() instead of []
public function findAwaitingPaymentTransactionsByUserId( $dateRange = array() )
{
    // ...
}

... to resolve the issue.
