php.log: what is the proper way to clear log file?

Question

I'm troubleshooting a php log file that has expanded way too rapidly and used up a lot of disk space.

What is the best way to clear a log file?

is it a problem to simply delete the log file? And will that log file be recreated as php tries to write to it?

Answer 1

It is entirely safe to just delete the php.log file. It will be auto-created the next time it is needed.

Answer 2

On Linux you can do :

cat /dev/null > /var/logs/php.log   

Answer 3

On Mac OS X 10.6 I deleted /var/log/apache2/error_log. Minor panic when it didn't re-appear upon refreshing my page. Just had to restart apache by going through the Sharing settings. Now she's back.
