Looking for direction on PHP functions to learn/use to read display and compare data in multiple html files.

I am very much a novice with HTML and PHP and am looking for direction for the best approach to be able to read "table" data from multiple html files and display various elements as well as make comparisons, calculations, etc.  I have created spreadsheets in both Excel and Google that perform the same functions I'd like to duplicate and/or expand on in a web environment.

I have 26 weather stations that each use htx template files embedded with 120 x 2  data tags used to populate a 120 x 2 "table" of values in a html file.  These 26 files are recreated every 10 minutes as long as the software for each station is running.  An example of 1 of these 26 files can be seen here:

With Excel, each one of these station files is imported into its own station worksheet and can then be referenced within other worksheets for display, comparisons, etc.  When the workbook is open, the data is refreshed every 10 minutes so the newest data from the 26 html files is read in.  Attached is an image showing a worksheet comparing several data elements between the 26 stations.  Where every html file contains the same data in the same order, I assume it is probably possible to read in only the rows I'm using as opposed to all data from all files as I am doing in Excel but either way works.

Initially, I'm looking for direction for the PHP functions I need to learn/use to best duplicate what I am doing with Excel, mainly just being able to access the various data in the 26 html files.

Any help and direction will be greatly appreciated.

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>';
