'skip cloudflare view source page php

I have this code to fetch the source code of the sites, but there are some sites that use Cloudflare.. and it is not possible to fetch the source code

Is there a way to bypass Cloudflare?

// get url of redirect from source url & get url view source
$url = '/';
function get_remote_data($url, $post_paramtrs=false,  $curl_opts=[]){ 
    $c = curl_init(); 
    curl_setopt($c, CURLOPT_URL, $url);
    curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
    //if parameters were passed to this function, then transform into POST method.. (if you need GET request, then simply change the passed URL)
    if($post_paramtrs){ curl_setopt($c, CURLOPT_POST,TRUE);  curl_setopt($c, CURLOPT_POSTFIELDS, (is_array($post_paramtrs)? http_build_query($post_paramtrs) : $post_paramtrs) ); }

    curl_setopt($c, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($c, CURLOPT_MAXREDIRS, 10); 
    //if SAFE_MODE or OPEN_BASEDIR is set,then FollowLocation cant be used.. so...
    $follow_allowed= ( ini_get('open_basedir') || ini_get('safe_mode')) ? false:true;  if ($follow_allowed){curl_setopt($c, CURLOPT_FOLLOWLOCATION, 1);}

Cloudflare is a middleware. Your request goes through cloudflare and then to your server. You do not access to your site directly. If site disables cloudflare then you can access the site directly.
