How can I run a cron job with arguments and pass results to a log?
It looks like you are searching for the log file in the wrong folder.Try this
* * * * * cd /path/to/script.php ; ./script.php arg1 arg2 >> logfile.logThen look for your log file in the /path/to/script folder.It can also be a write permission problem.Also, check your script for errors.Your crontab command seems OK.
