Read the file with the file function (http://www.php.net/file). This will give you an array, with each element representing a line in the original file. Pop the last element away (http://www.php.net/array_pop) twice. The second time you do this, store the element you will gain (pop will return the element it popped). There you have it... In code: <? $content = file( 'http://waterdata.usgs.gov/ny/nwis/uv?format=rdb&period=1&site_no=01420500' ); array_pop( $content ); $current = array_pop( $content ); ?> HTH Erwin
