What are some good and easy solutions for running cron from php?

Question

linux

You need a ready-made library \ class \ script to work with cron from under php.
Do you recommend anything good? On ubuntu server if that matters.

Answer 1

Here is how I implemented it:

$output = shell_exec('crontab -l');
file_put_contents('/tmp/crontab.txt', $output.$rule.PHP_EOL);
echo exec('crontab /tmp/crontab.txt');

Where $rule is the command to be executed in the cron.

Answer 2

Refine your question. from PHP with cron usually don't work, it's from cron that work with PHP.

Answer 3

Hmm, I don’t know what to offer you, but this is Linux) there is a cron process there, it usually sits as root, what do you think it is intended for? I did not set up this process myself, but I think there are enough instructions on the Internet, such as this
