I for some reason am getting an error when trying to deploy my app to a live server.

I am getting this error :

Parse error: syntax error, unexpected '[' in public_html/dev/vendor/laravel/framework/src/Illuminate/Support/helpers.php on line 411

function class_uses_recursive($class)
	{
		$results = [];

		foreach (array_merge([$class => $class], class_parents($class)) as $class)
		{
			$results += trait_uses_recursive($class);
		}

		return array_unique($results);
	}

I am aware that Laravel 4 needs PHP >= 5.4 and I am currently running 5.4 on my host, as well as my dev environment (which the app runs fine) and in the code above I am aware that '[ ]' is shorthand for the older array();

This is probably something I am just overlooking but my brain seems to be not working well this morning.

Thanks in advance!
