Nginx和嘈杂的PHP错误日志

Whenever a PHP error occurs or the error_log() function is used in PHP on an Nginx/PHP-FPM server, the log entry is always in the format:

<TIMESTAMP> 506#0: *66699 FastCGI sent in stderr: "PHP message: <MESSAGE FROM PHP SCRIPT>" while reading response header from upstream, client: xx.xx.xx.xx, server: <SERVER>, request: "<HTTP CALL>", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "<HOST>", referrer: "<REFERRAL>"

Is there any way to make this cleaner so that there isn't so much excessive text like the way Apache logs errors? For example:

<TIMESTAMP>, <IP> <PHP MESSAGE>, <REFERRAL>
