  0  8  *  *  *  http://www.mywebsite.com/update1.php

Cron Job does not run a URL . It runs a local file / script . In your case, you should run `update1.php` as PHP CLI. Alternatively, you can use `wget` to run the URL. These two methods are different. Choose wisely. — Raptor, Apr 06 '16 at 07:19

You can use --spider option of wget for this purpose.

0  8  *  *  *  wget --spider http://www.mywebsite.com/update1.php

--spider indicates not to download anything (we just want to go through the pages, that’s all)

This line/code in your crontab:

http://www.mywebsite.com/update1.php

is not an execution of the script, it's just the url to it. You should download the php script, and put it locally on your linux server. That would make things simpler and much more reliable.

I would login to your linux server, use wget to download the script, chmod it to make sure it's executable, and mv it to wherever you want on your server:

wget http://www.mywebsite.com/update1.php -O update1.php
chmod 755 update1.php
mv update1.php /path/to/where/you/want/script

Then now that you have the script locally on your linux server, edit your crontab (crontab -e), and add the following line:

0 8 * * * /path/to/where/you/want/script/update1.php
