PHP /正则表达式解析NGINX错误日志

错误条目如下所示：

2011/06/10 13:30:10 [error] 23263#0: *1 directory index of "/var/www/ssl/" is forbidden, client: 86.186.86.232, server: hotelpublisher.com, request: "GET / HTTP/1.1", host: "hotelpublisher.com"

我需要解析：

date/time
error type
error message
client
server
request
host

第一位(解析日期)很容易使用substr.虽然我的REGEX不太好,但我希望能听到更好的解决方案.我想,简单的爆炸,也不会起作用,因为错误也可能包含逗号.

最有效的方法是什么？

解决方法:

关于什么：

$str = '2011/06/10 13:30:10 [error] 23263#0: *1 directory index of "/var/www/ssl/" is forbidden, client: 86.186.86.232, server: hotelpublisher.com, request: "GET / HTTP/1.1", host: "hotelpublisher.com"';
preg_match('~^(?P<datetime>[\d+/ :]+) \[(?P<errortype>.+)\] .*?: (?P<errormessage>.+), client: (?P<client>.+), server: (?P<server>.+), request: (?P<request>.+), host: (?P<host>.+)$~', $str, $matches);
print_r($matches);

输出：
