Cron is a simple Linux module which allow user to run command at regular interval of time.

It is commonly used to perform system maintenance or administration.

Run a PHP script on cron : If your PHP scripts do not have executable permissions, 644 or -rw-r--r-- (which is different code for tread permission and write permission ) for example, then as part of the command portion of the cron line, you must specify the php interpreter and pass it the filename of the PHP script.

With cron jobs, you can exactly plan when a certain command is to be executed. Sure you can create simple scripts for each job and run them all separately via a Unix crontab, but this self-contained script allows running unlimited jobs all from one file.

To get a crontab to call a php script You'll need some basic knowledge of unix shell commands.Users can have their own individual crontab files and often there is a systemwide crontab file (usually in /etc or a subdirectory of /etc).

Scripts to emulate crontab : Pseudocron, a simple PHP script and Fake Cron (you don't have access to Cron, then this CGI will help you by imitating Cron) Yes, you can run in a crontab in php. What you need is php compiled as a cgi (you can have both cgi and apache module).
