Are you sure you're looking at the right log file? Sometimes PHP logs errors to the Apache error log (e.g. /var/log/apache/error.log or /var/log/httpd/error_log etc.) and sometimes it logs errors to the system log (e.g. /var/log/messages, /var/log/syslog, etc.). The above entries look like the access log, and they don't indicate any trouble.
