My jaw hit the desk on this one, guys. Do not allow the webserver to
create php scripts, under any circumstances ever. It's just asking for
Abstract the data (job listings) into a text file or sqlite database
and give the webserver password protected write access to that. Or use
a .csv file and edit the records by hand using Excel or EditGrid.com.
If you need to create world-writeable directories for uploaded files
(and you _do_ need them sometimes), you should also take steps (via
Apache config or .htaccess) that php scripts residing in those
directories cannot be executed.
