I have a PHP routine that does an RSS website scraping process only
once per day - I use an external file to trigger whether it does
anything or not. Here's what I use:
$inData = file_get_contents('/xml/ts/data1.txt');
$str = file_put_contents('/xml/ts/data1.txt', $pubDate);
if ($inData != $pubDate) { ...do this process ... }
The first statement retrieves a publication date that was last saved.
The second statement writes the new publication date to the file.
Then, I only do my daily process if the publication date I retrieved is
different from the one I just wrote. Technically, I probably should
only write the new date AFTER my process is complete -- just in case a
problem occurs and the process doesn't complete.
But, anyway, those two functions are a nice easy way to read and write
a flat file.
