pseudo-cron 1.3

With cron jobs, you can exactly plan when a certain command is to be executed. But most homepage owners can't create cron jobs on their web server – providers demand some extra money for that.
The only thing that's certain to happen quite regularly on a web page are page requests. This is where pseudo-cron comes into play: With every page request it checks if any cron jobs should have been run since the previous request. If there are, they are run and logged.
Pseudo-cron uses a syntax very much like the Unix cron's one. The syntax pseudo-cron uses is different from the one described on that page in the following points:
· you may not use abbreviations (Mon, Tue, ...) for day of week
· there is no user column
· the executed command has to be an include()able file (which may contain further PHP code)
All job definitions are made in a text file on the server with a user-definable name (usually crontab.txt).
Features: 
· runs any PHP script
· periodical or time-controlled script execution
· logs all executed jobs
· can be run from an IMG tag in an HTML page
· follows Unix cron syntax for crontabs
· sends an email with the results
Usage: 
· Modify the variables in the config section below to match your server.
· Write a PHP script that does the job you want to be run regularly. Be sure that any paths in it are relative to the script that include()s pseudo-cron.
· Set up your crontab file with your script
· Include pseudo-cron.inc.php in a high traffic page
· Wait for the next scheduled run
