You could use regex like this one to help you out: https://regex101.com/r/UBhSCM/1 — Igor Ilic, Jan 15 '19 at 07:55

To locate comments within the HTML markup I would suggest that a regex is probably not the best method but you can accomplish the stated aim easily using DOMDocument and DOMXPath. There is, within XPath 2 a comment() function that you would use in the XPath query - viz: $xp->query('//node/comment()') etc

$strhtml='
    <html>
    <head>
        <title>duff html</title>
    </head>
    <body>
    <!--
        first of too many
    -->
    <!--Array
            (
                [0] => Pagedale
                [1] => 3,304.
                [2] => 1.19
                [3] => $28,480
                [4] => 93.43%
                [5] => 22.40%
                [6] => 0.2640
                [7] => 0.3410
                [8] => 0.0000
                [9] => 0.3500
                [10] => $189,823
                [11] => 6.83%
                [12] => 8.363%
                [13] => $1,090,378
                [14] => 39.25%
                [15] => 1
                [16] => $2,434,084.00
                [17] => $2,778,093
                [18] => $2,540,416
                [19] => Sales Tax

                [25] => Parks & Recreation
                [26] => $475,127
                [27] => Police

                [36] => 12.66%
                [37] => $90,758
                [38] => $351,583
                [39] => 1420 Ferguson Ave
                [40] => Pagedale

            )
            -->
                <div>Hello world </div>

                <!-- last comment -->
                <div> Last div </div>
            </body>
           </html>';


    $dom=new DOMDocument;
    $dom->loadHTML( $strhtml );
    $xp=new DOMXPath( $dom );
    $col=$xp->query('/html/body/comment()');

    if( $col && $col->length > 0 ){
        $comments=[];
        foreach( $col as $comment ){
            $comments[]=$comment->nodeValue;
        }
        printf('<pre>%s</pre>',print_r($comments,true));
    }

Will output:

Thanks but when i try to save those html in a file and try to load it $strhtml = file_get_contents('str.html'); It show some errors. Warning: DOMDocument::loadHTML(): Tag header invalid in Entity, line: 97 in C:\xampp\htdocs\projects\regex\index.php on line 5 here's the line 5 $dom->loadHTML( $strhtml ); — Raw Scripter, Jan 15 '19 at 09:00
please explain further - do you mean when you try to save the HTML comments to file? Or the entire HTML page ( YOUR html example is invalid HTML and will cause an error with DOMDocument generally )?? — Professor Abronsius, Jan 15 '19 at 09:15
