I need a simple 'Online Article Submission' script which submits only one article at a time, to only one article directory (among many, say 500+, and this script should be able to submit to any of them selected, one at a time).

When this script is run (normally by a cron job), it should start reading from the first entry in an online database of scheduled articles for the day. (I would have created this online database already; creating this is not part of the assignment.)

The entries in the scheduler database would be the details of the article to be submitted and the article directory to which the article has to be submitted. (Again, I would have created the article database from which articles will have to be taken.)

The script will only submit that particular (one) article to that particular (one) directory, and return to read the next entry in an online database of scheduled articles, and repeat the above process till it completes the list of scheduled articles. The submission process may involve logging into the article database online, using the authentication info that would be part of the article directory info that it reads. If these login info are blank, then it means the directory permits posting articles without a login process.

Details of the article to be stored will be article title, author, body of the article, brief summary, author bio, and category.

You may like to see scripts like article dashboard, article submitters sold thru eBay, and the ones referred to in hotscripts.com, in addition to services like article submitter and article post robot if you're new to all this.
