Overview
  • Cron Jobs are scheduled tasks such as logging, backup, and checking whether a Web page works properly. In Ubuntu, you can simply edit an existing text file, inserting a line of 5 segments of text: "M H D M weekday command". You can use that "command" to run PHP script to update database, for example. In Windows, if you are running XAMPP package, you would use Window's own Task Scheduler to run that same PHP script.

  • What Is Crontab? A crontab is a simple text file that holds a list of commands that are to be run at specified times. These commands, and their related run times, are controlled by the cron daemon and are executed in the system's background. More information can be found by viewing the crontab's man page. We will run through a simple crontab example later. How Does It Work? The system maintains a crontab for each user on the system. In order to edit or create a crontab, you mus

  • Use CURL, WGET, or PHP command-line interpreter.

    A common method for running PHP scripts from a cron job is to use a command-line program such as curl or wget. For example, the cron job runs a command similar to the following command:

    curl http://example.com/script.php

    In this command, curl retrieves the web page, which then runs the PHP script.

    However, there is a better way to run PHP scripts on your web site from cron jobs. You can run the script directly by using the PHP command-line interpreter. This method is just as effective, and usually faster. The following command shows how to run a script using the PHP command-line interpreter:

    /usr/local/bin/php -q /home/username/public_html/script.php

    In this example, the PHP command-line interpreter runs the script.php file. The -q option enables quiet mode, which prevents HTTP headers from being displayed.
