Question

I have a PHP script that is parsing an RSS feed and entering the info in a db. I am using PHP5.

It is a .php page, and works like a charm when accessed through the web server & browser. (http://myhost.com/rssjob.php)

Now i want to set it up as a CRON job – however when i execute it through SSH/CRON job – it throws exceptions like ” Invalid argument supplied for foreach() ” in following code.

Question:
1. Why is there a delta in the results i get through accessing the PHP page throw the browser and when i try to execute it as a CRON job/SSH command line?? Is there something more i should specify for the php page to work well when accessed through SSH/commandline/cron job?

$xml = parseRSS(“http://www.myhost.com/rss/”);

//SAMPLE USAGE OF 
foreach($xml['RSS']['CHANNEL']['ITEM'] as $item) {
        //echo("<p>");
    $title = $item['TITLE'];

    $description = $item['DESCRIPTION'];

Answer 1

A quick solution (hack) is to call your script via HTTP from cron:

? * * * * curl http://PATH.TO.YOUR/script.php
