How to erase content?

[mooger35]

What I want to do is write to a file (no problem... I figured this out) but if there is already text there I want to clear it before writing to the file (this is where I'm stuck).

when you use fopen [php.net] just use the w mode

Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

wonderful!

Works great.

now final question. I have the file (write.php) that will erase then rewrite the file in question.

I would like to set up a cron job to run this file (write.php). How do I do that with cpanel 2.5's cron job function?

Command to run:?

Thanks!

ps: I hope this is okay to ask in this forum.

I don't use cpanel, but for running php scripts from cron, I usually use something like:
/usr/bin/php /home/mcavic/write.php
