这个wordpress PHP代码有什么问题？(来自教程)

Question

我知道这通常是不赞成的,但是我从教程中得到了这个,所以我对它为什么不起作用感到有些惊讶.

这是受影响的代码行:

$document_root = rtrim(str_replace(array('/', '\'), '/', $_SERVER['DOCUMENT_ROOT']), '/');

apache错误日志中的错误消息:

[Sun Jul 27 01:01:47 2014] [error] [client 24.62.230.8] PHP Parse error:  syntax error, unexpected 'DOCUMENT_ROOT' (T_STRING), expecting ')' in /home/folder/wp/wp-config.php on line 8

上下文:这是我为实现这一目的而遵循的教程.查看wp-config.php - http://polycademy.com/blog/id/148/modern_wordpress_workflow_with_composer

尝试这样的事情:

$document_root = rtrim(str_replace(array('/', '\\'), '/', $_SERVER['DOCUMENT_ROOT']), '/');
