How to extract the direct Sibnet video url PHP - php

Question

I'm searching for a solution to this problem for a long time and I didn't get any solutions.
I managed to extract the mp4 URL, ​​but the problem is that this link redirects to another URL that can be seen in response header: Location, I don't know how I can get this URL.
Response Header(img)
<?php
function tidy_html($input_string) {
$config = array('output-html' => true,'indent' => true,'wrap'=> 800);
// Detect if Tidy is in configured
if( function_exists('tidy_get_release') ) {
$tidy = new tidy;
$tidy->parseString($input_string, $config, 'raw');
$tidy->cleanRepair();
$cleaned_html = tidy_get_output($tidy);
}
else {
# Tidy not configured for this Server
$cleaned_html = $input_string;
}
return $cleaned_html;
}
function getFromPage($webAddress,$path){
$source = file_get_contents($webAddress); //download the page
$clean_source = tidy_html($source);
$doc = new DOMDocument;
// suppress errors
libxml_use_internal_errors(true);
// load the html source from a string
$doc->loadHTML($clean_source);
$xpath = new DOMXPath($doc);
$data="";
$nodelist = $xpath->query($path);
$node_counts = $nodelist->length; // count how many nodes returned
if ($node_counts) { // it will be true if the count is more than 0
foreach ($nodelist as $element) {
$data= $data.$element->nodeValue . "\n";
}
}
return $data;
}
$vidID = 4145616; //videoid : https://video.sibnet.ru/shell.php?videoid=4145616
$link1 = getFromPage("https://video.sibnet.ru/shell.php?videoid=".$vidID,"/html/body/script[21]/text()"); // Use XPath
$json = urldecode($link1);
$link2 = strstr($json, "player.src");
$url = substr($link2, 0, strpos($link2, ","));
$url =str_replace('"',"",$url);
$url = substr($url , 18);
//header('Location: https://video.sibnet.ru'.$url);
echo ('https://video.sibnet.ru'.$url)
?>

<?php
$url='https://video.sibnet.ru'.$url;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$a = curl_exec($ch);
$url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL); // This is what you need, it will return you the last effective URL
$realUrl = $url; //here you go
?>
