Cron Job refers to the execution of a specific PHP script at regular intervals, which is essential for ensuring the seamless operation of a particular system. Certain tasks, such as sending notifications, emails, and clearing the cache, require execution in the background and are initiated by the system itself. These tasks are pre-defined and need to be carried out consistently. It is vital to ensure that the PHP script runs regularly, which can be achieved either by executing it manually each time or by automating the process to specify the desired frequency of execution.
