How to update database from other site periodically using php?
<p>Say my site lists items from other sites, for example, I listed ebay items, what I want to do is when the ebay items be sold out the corresponding item info on my site can be updated, how can we do this using php?</p>

<p>Of course we can start a scheduled process on the hosting server, however we don't have privilege to do that for we only have spaces to host php and mysql.</p>

<p>Any help is highly appreciated!</p>
