PHP Cron Job

Trying to run a cron via the crontab in a user account, doesn't seem to trigger the job.
Cron was set to run every 5 mins, and the command line to the php script used is as follows: php -f /home/demo/public_html/cron.php

This however doesn't seem to be working - although the cron saves & shows as active in the webpanel.

Any ideas?

try using a full path for your php

from command line you can get a full path
which php

Dear All.  This is how my cron job worked.

* * * * * /usr/local/bin/php /home/username/public_html/crontest.php

Hi in my case on Almalinux it was

* * * * * /usr/local/bin/php -f /targetdir/RunTasks.php >> /targetdir/logs/errors.log &2>1

as I wanted to append >> an error as well however in my case " &2>1" did not work but works perfectly without it!

does anyone know why?

thought I would post this to help others, if you want the error log also include your usual error settings at the head of the script i.e.
in my case wanted everything
error_reporting(E_ALL); // Error/Exception engine, always use E_ALL
ini_set('ignore_repeated_errors', TRUE); // always use TRUE
ini_set('display_startup_errors', true);
ini_set('display_errors', true); // Error/Exception display, use FALSE only in production environment or real server. Use TRUE in development environment
ini_set('log_errors', TRUE); // Error/Exception file logging engine.
ini_set('error_log', '/targetdir/logs/errors.log'); // Logging file path
