Lets say I have created one php cron job file mycron.php with this content
<?php
// my cron function start here
echo "yea! my cron is running \n";
Then I create a cron job to run this file automatically, for example
For Nginx server
/RunCloud/Packages/php74rc/bin/php /home/runcloud/webapps/myapp/mycron.php
For Openlitespeed
/usr/local/lsws/lsphp74/bin/php /home/runcloud/webapps/myapp/mycron.php
In this example, /home/runcloud/webapps/myapp is my webapp rootpath, you can change it with your own.
The cron job should work properly.
But the mycron.php file is still accessible from the browser http://yourdomain/mycron.php
If you want to make it only accessible to terminal / cronjob, not by direct access in the browser, then you have to do something.
There are some possible ways to do it, for example, you can modify your code and use php_sapi_name function to detect if it is called from terminal / cronjob.
For example
<?php
// allow via cronjob or via cli
if (php_sapi_name() !== "cli") {
die("invalid request");
}
// my cron function start here
echo "yea! my cron is running \n";
Now, if you try to access this file from your browser, you will see "invalid request" message in your browser.
