Alternatively, assuming they all have same rigid structure, ... $fp = file('weather.html', FILE_IGNORE_NEW_LINES|FILE_SKIP_EMPTY_LINES); $data = []; foreach ($fp as $line) { switch (substr($line, 0, 4)) { case '<!--' : if ($line[4]!=' ') { $section = substr($line, 4, -8); } break; case '<td>' : list($name, $value) = getData($line); $data[$section][$name] = $value; break; default : continue 2; } } function getData($line) { $l = substr($line, 4, -5); return explode('</td><td>', $l); } // View the results echo '<pre>' . print_r($data, 1) . '</pre>'; giving ... $data = Array ( [MISCELLANEOUS] => Array ( [Name of Station] => AzureCove [City (from NOAA Setup)] => Garden City [State (from NOAA Setup)] => Utah [Elevation (from NOAA Setup)] => 5954 ft [Latitude (from NOAA Setup)] => 41° 56' 12" N [Longitude (from NOAA Setup)] => 111° 23' 20" W [Date on the PC] => 03/13/23 [Time on the PC] => 4:06a [UTC Time] => 10:06a [UTC Date] => 03/13/23 [Date on the Station] => 03/13/23 [Time on the Station] => 4:05a [Sunrise Time] => 7:41a [Sunset Time] => 7:30p [Current Weather Forecast *] => Partly cloudy with little temperature change.

You are referencing aliases before they have been defined. For example, you dont define the table alias "b" until the last line of the query but you are referencing it several time earlier subqueries in the query. Why output identical values twice? ... SELECT a.prod_name , a.prod_size , ifnull(a.qty_received, 0) qty_received , ifnull(b.qty_bot, 0) qty_bot , ifnull(a.qty_received, 0) - ifnull(b.qty_bot, 0) qty_remain FROM ( SELECT prod_id FROM tbl_distribution UNION SELECT prod_id FROM tbl_sales_bar ) t LEFT JOIN ( SELECT prod_id, prod_name, prod_size, SUM(prod_qty) qty_received FROM tbl_distribution WHERE staff_id = 2962 GROUP BY prod_id ) a on a.prod_id = t.prod_id LEFT JOIN ( SELECT prod_id, SUM(qty_bought) qty_bot FROM tbl_sales_bar WHERE staff_id = 2962 GROUP BY prod_id ) b on b.prod_id = t.prod_id; results +---------------+-----------+--------------+---------+------------+ | prod_name | prod_size | qty_received | qty_bot | qty_remain | +---------------+-----------+--------------+---------+------------+ | 33 | | 13 | 8 | 5 | | Star Wrangler | | 7 | 6 | 1 | | Star | | 19 | 7 | 12 | | Goldberg | | 10 | 0 | 10 | +---------------+-----------+--------------+---------+------------+1 point
