Data retrieval

Need transportable module to retrieve select daily streamflow data for selection of Montana rivers and display data in websites I create. See [login to view URL] "streamflow" sidebar for example. Using following URL format, I can choose streamflow data from select rivers on specific dates: [login to view URL] &site_no=06043500 *Specific site on individual river (Need to be able to input select various river codes) &cb_00060=on *Specific code for streamflow &begin_date=2009-01-16 *Begin date &end_date=2009-01-16 *End date (always the same as begin date for daily data) &format=rdb NOTE: above URL sent as single line without notes. I'm assuming [login to view URL] uses the USGS waterdata system for data. Desired 'module' would allow me to enter various river/site codes, always using streamflow code, then retrieve data for variety of rivers on a daily basis and display results in webpage. Local programmer has set up a method using a cron job on host server that collects above data via cURL exec within PHP script which then fwrites data to CSS-styled UL/LI layout 'included' in php webpage. Works OK, but there may be a more compact way.
