php - simple_html_dom: 403 Access denied


I implemented this function in order to parse HTML pages using two different "methods". As you can see both are using the very handy class calledsimple_html_dom. The difference is the first method is also using curl to load the HTML while the second is not using curl

Both methods are working fine on a lot of pages but I'm struggling with this specific call:searchThroughDOM('', 'simple_html_dom');

In both cases, I end up with a 403 access denied response. Did I do something wrong? Or is there another method in order to avoid this type of denial?

function searchThroughDOM ($url, $method)
    echo '$url = '.$url.'<br>'.'$method = '.$method.'<br><br>';
    $time_start = microtime(true);

    switch ($method) {
        case 'curl':
            $curl = curl_init();
            curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($curl, CURLOPT_HEADER, false);
            curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
            curl_setopt($curl, CURLOPT_URL, $url);
            curl_setopt($curl, CURLOPT_REFERER, $url);
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36');
            $str = curl_exec($curl);

            // Create a DOM object
            $html = new simple_html_dom();
            // Load HTML from a string

        case 'simple_html_dom':
            $html = new simple_html_dom();

    $collection = $html->find('h1');

    foreach($collection as $x => $x_value) {
        echo 'x = '.$x.' => value = '.$x_value.'<br>';


    $time_end = microtime(true);
    echo 'Elapsed Time (DOM) = '.($time_end - $time_start).'<br><br>';



From my point of view , there is nothing wrong with "simple_html_dom" you may remove the simple html dom "part" of the code , leave only for the CURL which I assume is the source of the problem. There are lots of reasons cause the curl Not working on page first of all I can see you add

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); you should also try to add CURLOPT_SSL_VERIFYHOST , false

Secondly , check your curl version, see if it is too old third option, if none of above working , you may want to enable cookie , it may possible the cookie disabled cause the website detect it is machine, not real person send the request . lastly , if all above attempt failed , try other library or even file_get_content , Curl is not your only option, of cause it is the most powerful one.

People are also looking for solutions to the problem: When I run PHP function to append parameter to array, it only shows the most recent parameter passed as the only element within the array
