PHP Help (self execution script)

[kyosho]

Hi,

I want to write a script that checks for XML on specific sites daily without me having to manually execute, parse the XML, and post a link on my site to that site.

Do any of you know if it's possible to to have some bot in PHP that could do this say... 2 times a day at specific times without me having to manually execute the script? If so, could you please direct me to where I might find this information. If not, do you know any other web languages out there that are self executing that could do this? I've been coding with OOP applicational languages for a while, and the way I've done it before was to just leave the program running which I dont know is possible with a script language. So any ideas or suggestions would be much appreciated

thanks

write the script, then run it as a cron job.

thanks.. had to look up the term 'cron job' but makes perfect sense to me now. Thanks again
